  Terra Seismic can predict most major earthquakes (M6.2 or greater) at least 2
- 5 months before they will strike. Global earthquake prediction is based on
determinations of the stressed areas that will start to behave abnormally
before major earthquakes. The size of the observed stressed areas roughly
corresponds to estimates calculated from Dobrovolskys formula. To identify
abnormalities and make predictions, Terra Seismic applies various
methodologies, including satellite remote sensing methods and data from
ground-based instruments. We currently process terabytes of information daily,
and use more than 80 different multiparameter prediction systems. Alerts are
issued if the abnormalities are confirmed by at least five different systems.
We observed that geophysical patterns of earthquake development and stress
accumulation are generally the same for all key seismic regions. Thus, the same
earthquake prediction methodologies and systems can be applied successfully
worldwide. Our technology has been used to retrospectively test data gathered
since 1970 and it successfully detected about 90 percent of all significant
quakes over the last 50 years.
