Reply to comment by P. Rydelek et al. on "Earthquake magnitude estimation from peak amplitudes of very seismic signals on strong motion records"
No full textBased 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.PublishedL203033.1. Fisica dei terremotiJCR Journalreserve
Inferences on the source mechanisms of the 1930 Irpinia (Southern Italy) earthquake from simulations of the kinematic rupture process
Full text linkWe examine here a number of parameters that define the source of the earthquake that occurred on 23rd July 1930 in Southern Italy (in the Irpinia region). Starting from the source models proposed in different studies, we have simulated the acceleration field for each hypothesized model, and compared it with the macroseismic data. We then used the hybrid stochastic-deterministic technique proposed by Zollo et al. (1997) for the simulation of the ground motion associated with the rupture of an extended fault. The accelerations simulated for several sites were associated with the intensities using the empirical relationship proposed by Trifunac and Brady (1975), before being compared with the available data from the macroseismic catalogue. A good reproduction of the macroseismic field is provided by a normal fault striking in Apenninic direction (approximately NW-SE) and dipping 55° toward the SW
