[1] Based on the analysis of Mediterranean, near-source, strong motion records Zollo et al. [2006] (hereinafter referred to as ZLN) showed that peak displacement amplitudes of initial P- and S-wave seismic signals scales with the earthquake size in the moment magnitude range 4 < Mw <7.4. Similar evidence have been also reported for southern California [Wu and Zhao, 2006] and Taiwan [Wu et al., 2006] using only P-wave arrivals up to 100 km distance on mostly short period and broadband waveform data.
[2] As discussed by ZLN, these observations may be of potential use for earthquake early warning applications but also provide important insights on the physical processes which control the early stage of earthquake rupture nucleation
and propagation.
