meaurement by richte scale . the prediction regarding the earthquke is determined by the radon gs emission from the earth crust .
richter scale measures the intensity of eq , richter scale is caliberated from 1 to 10 in the measurement .
waves of earthquake
in the phenomenon of earthquake . two waves are emitting , p waves and s wves .
