In these primary waves, pulses of energy are transmitted as a succession of compressions and expansions that parallel the direction of propagation of the wave itself. Thus, a given segment of rock set in motion during an earthquake is driven into its neighbor and bounces back. The neighbor ...

We introduce a new scaling relation between earthquake magnitude (M) and a characteristic of initial P wave displacement. By examining Japanese K-NET data averaged in bins partitioned by Mw and hypocentral distance, we demonstrate that the P wave displacement briefly displays similar growth at the...
The earthquake motion of the 2011 off the Pacific coast of Tohoku Earthquake grew gradually larger and continued unusually long with high amplitude more than JMA intensity 4 in wide area. The single-station detection system FREQL succeeded to issue the P-wave alarm and estimated the earthquake pa...
