The Richter scale used to measure the magnitude of earthquakes, is based on the logarithm base 10. The measurements of the intensities of earthquakes grow exponentially. This means that if x is the magnitude of an earthquake, then the intensity is Y = 10 The table below shows some earthquakes recorded over time on the Richter scale: Based on the above data compare the intensity of earthquakes of San Francisco, 1989, with the earthquake in South Asia in October 2005. Compare also the intensity of the earthquake in Iran, 1990, with what happened in Chile in 2005. So, have you figured out what earthquakes and music have in common? How about now hear good music to feed the soul!

Richterova ljestvica koristi za mjerenje magnitudu potresa, temelji se na bazi 10 Logaritam. Mjerenja su intenziteta potresa raste eksponencijalno. To znači da ako je x magnituda potresa, onda je intenzitet Y = 10 Tablica u nastavku prikazuje neke potrese snimljene tijekom vremena po Richteru: Na temelju gore navedenih podataka usporediti intenzitet potresa u San Franciscu, 1989, s potresa u Južnoj Aziji u listopadu 2005. Usporedite i intenzitet potresa u Iranu, 1990, s tim što se dogodilo u Čileu 2005. Dakle, jeste li shvatili što potresi i glazba imaju zajedničko? Kako je sada čuti dobru glazbu nahraniti i dušu!
