QCN in the classroom (CBS News in Los Angeles) CBS news in Los Angeles interviewed teachers and students in Chaffey Union Joint High School District. Watch the story here. 11 Nov 2015, 1:11:43 UTC · Comment If You're Having Trouble Connecting Since the Big Move to CalTech.... Some people are having trouble connecting -- this is probably due to the operating system (it seems to mostly be a Windows problem) caching the old qcn.stanford addresses, and not liking the forwarding to qcn.caltech (probably a "safety feature" in Windows). You can try doing a "Reset Project" in the BOINC Manager program to see if that will correct things. If not, you may have to do a more drastic "Remove Project" and then "Attach Project" to our new URL: http://qcn.caltech.edu/sensor You may want to first go to the "Your Account" page at the website to make sure you know which email address you used, and find/recover your password information as you will need this to login again. 23 Jul 2015, 12:09:05 UTC · Comment QCN Move to CalTech Is Completed 16 July 2015 The move of the QCN project from Stanford to Caltech seems to have gone smoothly. Thanks to all involved at Stanford Earth Sciences and Caltech GPS for making this transition possible. There may be kinks to iron out over the next few days; but the project seems to be back up and running. You do not have to do anything on your BOINC account - as the QCN addresses/URLs are being forwarded automatically from Stanford to Caltech. 17 Jul 2015, 3:47:22 UTC · Comment QCN Move To CalTech Starting 7/13/2015 The QCN servers will be packed up at Stanford next Monday (July 13th) and FedEx'd overnight to CalTech. It is hoped that by the end of next week the servers will be online at CalTech and the project will begin running again. We are forwarding our Internet DNS from Stanford to CalTech so that machines connected to "qcn.stanford.edu" will be routed to the new server location automatically (probably qcn.caltech.edu). More information will be sent once things are back up and running - but it's most likely the project will be down the week of July 13th. You shouldn't have to do anything - BOINC will automatically connect once it detects the servers are back up. 7 Jul 2015, 16:51:52 UTC · Comment QCN is moving to CalTech in July! The QCN project servers will be moving to CalTech and will be hosted in the Division of Geological and Planetary Sciences (GPS). The exact dates are uncertain but it will probably be by mid-July. All of us on QCN wish to thank the staff at CalTech for hosting us (and at relatively short notice). There will probably be a few days "down time" when the servers are transported. The Stanford DNS will point this URL (qcn.stanford.edu) to the new home page at CalTech (probably qcn.caltech.edu). There will be more updates as we get closer to the actual move. 22 May 2015, 22:57:30 UTC · Comment QCN/BOINC app for Android Devices Now Available QCN now runs on Android ARM-processor devices (phones, tablets, etc) via BOINC for Android, which is available on the Google Play store: https://play.google.com/store/apps/details?id=edu.berkeley.boinc It is recommended to run using the default settings - ie QCN will run on your Android device when it's charging ("at rest" so it won't trigger every few seconds) and on a wifi network. The network and CPU requirements are very small, typically 1-5% CPU, and a few kilobytes per day. Just download BOINC for Android from the Google Play store link above, and attach to "qcn.stanford.edu/sensor" Note that this app is not graphical - we are looking to make a QCNLive-style Android add-on for displaying the QCN/BOINC app/accelerometer information. 1 Feb 2014, 20:11:31 UTC · Comment QCN Explorer Website for Demonstrating QCN Sensors and Earthquakes Our colleagues at the University of Delaware have created a website qcnexplorer.org in which you can simulate earthquake events and their effect on a QCN sensor network. 22 Jan 2014, 17:41:34 UTC · Comment Reinstall BOINC if Upgraded to Mac OS X 10.9 (Maverick) You should reinstall BOINC after upgrading to "Maverick" as the upgrade will lose the necessary BOINC accounts, hence the permissions in the directory will be wrong. You can download it from http://boinc.berkeley.edu/download.php 28 Oct 2013, 18:55:46 UTC · Comment US Gov't Shutdown - No USGS Data Note that due to the recent US government shutdown - the USGS will not be providing data for the QCNLive & QCN/BOINC earthquake map, and matching of USGS detected events to QCN events. Hopefully this issue will be resolved soon. 1 Oct 2013, 21:19:52 UTC · Comment QCN Open-Source on github We are opening up the source code for QCN for those of you who want to experiment (for example) with QCNLive and the sensors. The code is under the "LGPL" license (as are dependencies such as BOINC, Qt, etc) There are project workspace for Windows (Visual Studio) and Mac (XCode) in the respective win_build and mac_build directories to get you started. The project is on github at https://github.com/carlgt1/qcn 17 Jun 2013, 21:07:36 UTC · Comment NEES/QCN Open House for Future Teachers NEES@UCSB personnel hosted an open house for future science teachers in the Givertz Graduate School of Education at UC Santa Barbara in April 2013. Sandra Seale and Francesco Civilini, NEES project specialists, gave a training session in “Make Your Own Earthquake” using the QCN sensor. The teachers downloaded the QCN software and practiced making their own quakes and printing their graphs. Find out more information about NEES and Make-Your-Own-Earthquake here. 24 Apr 2013, 21:40:23 UTC · Comment BBC (UK) TV - Looking for videos of participants - what do you think of QCN? Dear all, We are working on a piece for British television for a science programme called the Dara O’Briain Science Club that will be broadcast in the UK to several million and many more around the world. We are working with the project leader Elizabeth Cochran to make a short insert for a prime time science show explaining the QCN. Elizabeth has kindly given me permission to contact the community via this forum. We are trying to demonstrate the success of the network so far – show how this is really just at the beginning but already people from all over the world are taking part. We are looking for participants to film themselves to tell us why they got involved with the network and what it means to them. It could be you, your partner, your children – anybody taking part! It could be filmed on an iPhone, webcam or similar – the quality isn’t important. We’d hope you’d be able to upload the video to a private YouTube channel on use drop box – a free upload service: https://www.dropbox.com/home Ideally what we are looking for is: • Your first name – and why you joined the quake Cather network – (about 30 seconds) • What are your hopes for the network? - (20 seconds roughly) • Wave at camera with name on card or similar (licence to be creative here!) - (about 20 seconds). Please contact me directly on duncan.singh@bbc.co.uk if you have any questions and to submit short videos. We aim to make a montage with the footage for use in the programme – to demonstrate the scale and success of the network. Thank you for your help! Duncan 25 Mar 2013, 12:13:41 UTC · Comment QCN Featured in TEDx Talk Project collaborator Debi Kilb gave a TEDx talk on ‘Using Videogames to Cultivate Future Scientists’ which includes a videogame created around the QCN project. Check out the video of her talk here. 5 Mar 2013, 19:18:34 UTC · Comment Windows 8 Compatibility and QCN We are seeing some trouble with the JoyWarrior USB sensors (particularly the 24F14) and Windows 8. It appears to be a Microsoft issue, ie somehow they are showing the sensor correctly but the values are all "0" for x/y/z. If you are using Windows 8 or thinking of moving to it, you may want to look into an alternative sensor such as the ONavi or Phidget.com models, which run fun in Windows 8. 17 Jan 2013, 23:02:51 UTC · Comment New Versions of QCN for All Platforms (v 7.29) I've just put up new versions of QCN/BOINC and QCNLive for all platforms, due to upgrades in the BOINC libraries as well as the development tools on Mac (Xcode4) and Windows (VS2010). There is no longer support for the MotionNode accelerometer, nor for the Mac PowerPC (PPC) platform (PPC Macs will still receive work but end at version 7.17). Support has been added for all Phidgets accelerometers (1042, 1044, 1056). These new versions will be downloaded to your host computer via BOINC at the end of your current workunit (usually within one day). If you wish to get them now, press the "Reset Project" button on your BOINC Manager. This may also be a good time to make sure that your computer location is set via the "Computer Location Info" button. 13 Jan 2013, 21:41:02 UTC · Comment QCN in Mexico in the News QCN has "sister projects in Taiwan (qcn.twgrid.org) and Mexico (www.ras.unam.mx). The project in Mexico recently attracted media attention there for their new deployment of our software. If you are in Mexico, you may want to attach to the project there rather than via QCN-Stanford, so as to be part of a denser group of sensors in Mexico.

The Phidgets 1056 and ONavi USB sensors work on them (I'm looking into the JoyWarrior problem). The Dreamplug seems to run much better than the Raspberry Pi - probably due to a better/faster USB implementation (although it costs US $159 versus US $ 35 for the Rasp Pi). Here are the instructions: http://qcn.stanford.edu/sensor/forum_thread.php?id=881 17 Aug 2012, 18:24:30 UTC · Comment QCN (& BOINC) for Raspberry Pi Debian "Wheezy" Linux If you have a Raspberry Pi ($35 ARM GNU Linux computer) and a QCN-approved USB sensor, you may be interested in trying out BOINC and QCN on it. Please refer to this thread on the QCN Sensor Linux Message Board: http://qcn.stanford.edu/sensor/forum_thread.php?id=880 11 Aug 2012, 4:15:40 UTC · Comment Using the Nintendo Wii Nunchuk on QCN Here is something of interest to electronics hobbyists: QCN Participant Jonathan Thomson has hacked together a way to use the Nintendo Wii Nunchuk controller as a QCN accelerometer. His work is documented at his blog: http://jethomson.wordpress.com/2012/05/16/using-a-wii-nunchuk-as-an-earthquake-sensor/ 22 May 2012, 12:26:13 UTC · Comment Phidget Spatial 1056 USB Accelerometer Support I have added support for the Phidget 1056 USB accelerometer for Windows and Mac with QCN. You need to install their Mac kernel driver for Mac OS X, but no driver is required for Windows. I hope to have support for Linux soon. http://www.phidgets.com/products.php?product_id=1056 16 Apr 2012, 19:55:45 UTC · Comment HP Laptops Supported (With HP 3D Hard Drive Protection) Thanks to Rafał Ostanek of Poland, I have managed to have QCN connect to HP laptops. It's still an "experimental beta test" - but if you use BOINC on your HP laptop (that has the HP 3D Hard Drive protection software installed and active), your HP laptop accelerometer should be able to be monitored by QCN. The sample rate is very low, so it will look different than other sensors (more "square wave") - but it does seem to detect triggers i.e. changes in acceleration etc. You have to get the version appropriate for your operating system, i.e. 64-bit Windows you should connect with a 64-bit BOINC client etc. And of course you need the HP hard drive protection software installed and enabled. There is no 64-bit Windows QCNLive, but if you have a 32-bit Windows on your HP laptop, you can try QCNLive (i.e. "offline" test): http://qcn.stanford.edu/sensor/download/qcnlive-win.zip Report success stories or failures in this thread. 5 Apr 2012, 13:47:56 UTC · Comment ONavi USB Sensors Work Under Linux The ONavi USB sensors (both the 12-bit and 16-bit) are now fully working under Linux with both QCNLive and QCN under BOINC. No drivers are needed to install. As the ONavi sensor shows up as a "pseudo-modem" (/dev/ttyACM0) you may need to check the permissions to ensure that your account has read/write permissions to this device. For example, you may have to add your account or the BOINC account to the "dialout" group so it has permissions to use the ONavi sensor. The other QCN USB sensors (JoyWarrior and MotionNode) already have Linux support. 1 Apr 2012, 3:56:10 UTC · Comment Angela Chung Receives 2012 Stanford-USGS Fellowship Please join us in celebrating Angela Chung’s great news. She will be the 2012-2013 Stanford-USGS fellow. Angela is a 4th year PhD student in Geophysics at Stanford working on many aspects of QCN. During the 2012-2013 academic year, Angela will continue to work on all things QCN, including testing low-cost MEMS sensors with John Evans (USGS). Way to go Angela! 15 Mar 2012, 0:35:56 UTC · Comment QCN Detects Earthquake In Seconds On Tuesday at 5:33AM, QCN detected a magnitude 4 earthquake near Berkeley, California within seconds of the earthquake origin. The event was detected 5-7 seconds before the strong shear waves reached Stanford University, where the QCN servers are located. 15 Mar 2012, 0:34:11 UTC · Comment QCN Upload/Download Server work I am moving a lot of data around so the download servers may be offline for a day (this shouldn't affect uploads from BOINC clients). 15 Mar 2012, 0:26:10 UTC · Comment Earthquake in Christchurch, New Zealand Watch this video and see a M5.2 earthquake send seismic waves across Christchurch, New Zealand on October 4, 2010. The circles show the location of seismic stations that recorded the event, including 118 QCN sensors and 29 GeoNet stations. The colors denote the intensity of the ground shaking, measured here as acceleration, with grey indicating no shaking and bright red indicating the most intense shaking during the event. The maximum acceleration measured on the stations was about 1 m/s/s, or approximately 10% of the force of gravity. The trace at the bottom is a type of a seismogram that shows the energy released versus time. The first small increase in energy is when the P-wave arrives at the station and the large jump in energy occurs when the larger amplitude S-wave arrives. You can see that there is continued shaking across Christchurch for 20-30 seconds, this late seismic energy is known as coda. It is due to the reverberations of the waves in the relatively loose soil that Christchurch is built on. This earthquake was one of many aftershocks recorded by both the permanent New Zealand network, GeoNet, and temporary QCN sensors. Approximately 180 QCN sensors were installed following the M7.1 Darfield earthquake that occurred on September 3, 2010. Since the mainshock there have been hundreds of smaller, but damaging aftershocks as large as M6.3. The QCN network recorded events ranging from M2.6 – M6.3. 27 Feb 2012, 1:08:59 UTC · Comment Sensor (Re)distribution in New Zealand GeoNet in New Zealand are looking to redistribute some QCN sensors in the area, if you are interested please see the GeoNet/QCN Press Release 7 Feb 2012, 4:34:02 UTC · Comment New QCN Paper on New Zealand Earthquake A new paper on QCN's work in New Zealand is available from the Annals of Geophysics: Comparison between low-cost and traditional MEMS accelerometers: a case study from the M7.1 Darfield, New Zealand, aftershock deployment 27 Jan 2012, 13:07:17 UTC · Comment President Obama Honors QCN Inventor Elizabeth Cochran QCN is proud to announce that Prof. Cochran has received a 'Presidential Early Career Award' from President Obama.

Download and install the new driver from http://qcn.stanford.edu/sensor/download/qcnusb-mac.zip . Then click 'Reset' in BOINC Manager to get the new version. The problem is in the Mac 64-bit 'human interface' (HID ie joystick etc) library - so the Mac versions are now for 32-bit PPC and Intel. 27 Jul 2011, 21:05:12 UTC · Comment Mac OS X 'Lion' Upgrade Problems (JoyWarrior Not Found) If you are upgrading your Mac to use the new 'Lion' version of OS X - there are some issues with BOINC and QCN you may want to consider. It may be necessary to reinstall BOINC after the upgrade due to a permission problem detected. Also it appears that the JoyWarrior sensors will not be found under BOINC (although work for QCNLive). This is possibly a permissions problem that will have to be looked at. The internal Mac laptop sensor should still work under QCNLive or BOINC (after a BOINC reinstall). 25 Jul 2011, 20:38:40 UTC · Comment 'Citizen-seismologists' sought to host tiny earthquake sensors on their computers QCN is rolling out an effort to recruit San Francisco Bay Area volunteers for QCN, as noted in this Stanford press release. 7 Jul 2011, 15:26:03 UTC · Comment QCN Server Upgrades Starting Thursday June 16th The servers are being upgraded today, and you may notice that they are down when you are trying to connect.

Several QCN stations installed in and around Christchurch recorded this earthquake. Due to the shallow depth of this event and proximity to Christchurch the shaking was quite severe in the city. The QCN stations recorded accelerations up to about 1g (9.8m/s/s), equivalent to the force of gravity. The QCN stations in the region continue to monitor the ongoing aftershock sequence. 22 Feb 2011, 19:20:00 UTC · Comment JoyWarrior 24F14 Sensor Setup for QCN We have unfortunately had a problem with the JoyWarrior 24F14 sensor setup, in that some were shipped out without the required 2g settings for QCN. Also the sensors cannot be setup within the QCN software unlike the 24F8 USB sensors. So if your sensor does not seem to be working correctly, please download this small program (for Mac and Windows), and follow the steps in the README.txt file. We apologize for any inconvenience. 13 Dec 2010, 22:13:00 UTC · Comment QCN at AGU Conference If you are going to the AGU Fall Conference in San Francisco next week, please look us up at our various exhibits/posters. 9 Dec 2010, 22:13:00 UTC · Comment Server Outages November 22nd - 24th, 2010 Due to construction in a new server room at Stanford, we expect intermittent outages between November 22nd and 24th. No action is required on your part as BOINC will just reconnect when the servers are back online. 4 Nov 2010, 23:23:00 UTC · Comment Upgraded QCN Software (version 5.83) New software is on the server which should fix some bugs, false/too many triggers, and enhanced processing of the seismic data files which reduces their size. You should automatically get this new version via BOINC within a day. Also a new feature is in place whereby we can get followup information after a quake (basically a trickle to our server with more information 4-5 seconds after the original trigger). Please report any problems to the 'Message Boards' (and hopefully this won't be the scariest thing you'll see this Halloween)! 30 Oct 2010, 5:34:00 UTC · Comment CNN News Story On QCN and Our 'Rapid Aftershock Mobilization Program' CNN has released a news story about QCN and some of our rapid response efforts in Chile and New Zealand. 17 Sep 2010, 17:40:00 UTC · Comment London Citizen Cyberscience Summit - 2-3 Sept 2010 Prof. Cochran will do a presentation on the Quake-Catcher Network at the London Citizen Cyberscience Summit on September 3rd.

It's in a new stylish red case. So if you placed an order you should be getting it soon, as they are being shipped out by our student helpers Tom and Jordan. We apologize again for the delay but it was out of our control due to production and shipping delays (the recent volcano in Iceland didn't help either!). The new sensor is fairy high sensitive, 14-bit resolution, and appears to be 16 times better than the previous sensors. We are still testing it on a shake table but preliminary results are very promising. Click here for the order form (still $49). 15 Jun 2010, 15:45:00 UTC · Comment QCN on Facebook QCN now has an 'official' group on Facebook. We hope to have news items, photos, and events listed here.

Many QCN participants detected this earthquake, as shown here. 16 Mar 2010, 12:00:00 UTC · Comment Los Angeles Times article on QCN Today there is a good article on QCN in the Los Angeles Times (click here), featuring Elizabeth Cochran and some of her 'schools outreach' work and an interview with a QCN participant. 12 Mar 2010, 12:00:00 UTC · Comment QCN responds to the M8.8 earthquake in Chile On March 9, two graduate students flew to Chile to begin installing 100 QCN sensors in the region affected by the recent M8.8 earthquake. Our partners at the University of Concepcion are coordinating the installation of sensors. Volunteers from the University of Concepcion and University of Santiago will assist with installing sensors in cities throughout the region. We hope to record many of the aftershocks that are still occurring in the area to better understand the distribution of aftershocks and to study the properties of earthquakes. We will include updates on their progress and the data that are recorded in the coming weeks. If you are in Chile and would like to participate in the Quake-Catcher Network Rapid Aftershock Mobilization Project (QCN-RAMP) please fill out the form on this link. 8 Mar 2010, 12:00:00 UTC · Comment QCN participant records the M8.8 earthquake in Chile On February 27, 2010 a M8.8 earthquake struck Chile just northwest of the major city of Concepcion. A QCN partner at the University of Concepcion was testing a JoyWarrior USB sensor with the goal of introducing QCN to the region in the future. The sensor caught the M8.8 mainshock and a number of aftershocks that followed. The computer was attached to a backup power supply that kept the computer running for one hour after the earthquake knocked out power to most of the city. Unfortunately, at the time of the earthquake the sensor was not connected to the floor, but most of the earthquake record looks surprisingly good. The very high accelerations approximately 15 seconds into the record may be the sensor falling off of the box it was sitting on. Click here to view the QCN output. 27 Feb 2010, 12:00:00 UTC · Comment QCN Participant Detects Illinois M3.8 Quake A rare midwestern US earthquake was detected by a QCN participant in Illinois. The quake was of magnitude 3.8 and was 45 miles northwest of Chicago, Illinois. The quake was only one of three detected in the upper Midwest in the past 21 years.

This is a fairly rare event to capture on QCN and we thank him and others running QCN! The participant's computer was only 10km from the epicentre. 5 May 2009, 0:00:00 UTC · Comment QCN Participants Detect M4.0 earthquake in Yorba Linda, California Two Quake-Catcher Network participants felt and recorded yesterday's magnitude 4.0 earthquake in Yorba Linda, California (southern Cal, southeast of Los Angeles). You can view some of the data at this link. They are only about 4 km / 2.4 miles from the epicenter, so it was a good test of QCN and the JoyWarrior USB sensors! Happily everyone is OK with just a few plates shaken up etc.  24 Apr 2009, 0:00:00 UTC · Comment Minimum BOINC Version 6.2 for QCN (6.6+ preferred) QCN is going to require a BOINC client upgrade (within the next two weeks) to at least version 6.2. This will enable QCN to run more reliably tanks to new BOINC features such as higher-priority CPU scheduling for low-CPU tasks such as QCN. Download the latest version here. We recommend BOINC version 6.6 or higher, as available on the download link, to ensure that your QCN software and sensor will work at a higher priority level, and cut down on the 'resets' especially when running other BOINC projects alongside QCN. 22 Apr 2009, 0:00:00 UTC · Comment Hawaii Quake Detected; QCN Is Now 'Non-Alpha' A few QCN participants caught the recent M5.1 quake in Hawaii. Also as of today I am removing the 'alpha test' status of the Quake-Catcher Network, although the URL will remain the same so you do not have to reconnect/reattach. The credit stats should now be tracked by boincstats.com  21 Apr 2009, 0:00:00 UTC · Comment QCN Participant Machines Detect Today's San Jose M4.2 Quake At least four QCN participant's machines detected today's San Jose earthquke.

It will hopefully lead to less 'false positive' triggers/trickles as well as help us 'fine tune' our algorithm. 7 Nov 2008, 0:00:00 UTC · Comment New version 4.22, All Platforms New version 4.22 is up for all platforms. This has improved error handling. If you are using the JoyWarrior 24F8 external USB accelerometer, you will want to upgrade the QCN USB driver software for Intel Mac or for PowerPC Macs. 4 Nov 2008, 0:00:00 UTC · Comment New Version 4.00, With BOINC Credits and Graphics Upgrades In honor of my hometown team the Philadelphia Phillies winning the World Series, I put up a new version (4.00) that will track how much time you've run QCN, and grant BOINC 'cobblestone' credits accordingly. This new version also has some improved graphics in the screensaver (in my biased opinion :-). The 'bouncing cube' now shows a plot of your accelerometer on each cube face, the earth view has a nice multitexture of the earth at day and night (if your graphics card supports it), and in screensaver mode it will cycle through these different scenes so you will get some variety. Also I have made workunits shorter - that way after a 'day' of run-time on QCN, you will get a new workunit and new software versions. This is an 'optional' upgrade now if you 'Abort' your current workunit or 'Reset Project.' Once we have a few people running 4.00+ for a few days I will send out an automatic message to upgrade. 30 Oct 2008, 0:00:00 UTC · Comment Trigger Maps for QCN Participants!

Linux. The Windows version supports the MotionNode Accel USB accelerometer, and all versions support the JoyWarrior24F8 USB accelerometer (Mac requires the driver for the JoyWarrior - see below). To get a new version hit the 'Reset Project' or 'Task / Abort' button on your BOINC Manager client. 16 Oct 2008, 0:00:00 UTC · Comment New Versions (3.47) for Mac and Windows, JoyWarrior 24F8 support There are new versions (3.47) for Intel & PowerPC Mac OS X and Windows that should fix some problems with stability and graphics. Also, support for the JoyWarrior 24F8 sensor is in place as well. If you are running BOINC on a Mac, you will need to download a small driver program and install it so that the QCN software running under BOINC can read the JoyWarrior sensor (this is not needed for 'built-in' laptop accelerometers). The Intel Mac driver is here and the PowerPC Mac driver is here . The Intel Mac driver is a hopefully 'easy to follow' installation program; unfortunately the PowerPC Mac driver is a simple shell script you will need to unzip and run in a 'Terminal' window. JoyWarrior 24F8 support on Windows is also in place, and should not require a separate driver program (at the current time!). As usual, please report problems/questions in the Message Boards. 4 Oct 2008, 0:00:00 UTC · Comment QCN article in the 9/25/08 issue of 'The Economist' magazine This week's issue of 'The Economist' (Sept. 25th '08) has an article on QCN written by Francois Grey of CERN. You can read it online here  25 Sep 2008, 0:00:00 UTC · Comment Note (and fix) for BOINC Crashes Please note if your BOINC running QCN seems to hang or crash. There is a bug in BOINC for long account files > 64KB -- basically if the historical earthquake list gets too large then BOINC will not start and may seem to hang. Unfortunately the only solution is to quit BOINC, and remove this file 'account_qcn.stanford.edu_sensor.xml' which is located (on Macs) at /Library/Application Support/BOINC Data (or Windows check c:\program files\BOINC). You should then be able to start BOINC and you will have to reattach/relogin to the QCN project. Sorry for the inconvenience! 9 Aug 2008, 0:00:00 UTC · Comment QCN Testers Detect Quake in Los Angeles There was a magnitude 5.4 earthquake east of Los Angeles, detected by about 15 machines running QCN. Click here for more details. Most machines reported back to the servers with 2-4 seconds of the initial detection trigger. These results (in addition to the previous quake in Reno a few months ago) show great promise for the QCN software! So thanks and keep running QCN! 29 Jul 2008, 0:00:00 UTC · Comment New Version of Software Available (version 2.81) New versions (2.81) have been put up for all platforms supported by QCN (Mac Intel, Mac PPC, Windows).
