DOI: 10.1007/s00024-017-1558-2
Abstract: Mechanisms are suggested that could explain anomalously high PGAs (peak ground accelerations) exceeding 1 g recorded during the 2011 Tohoku earthquake (Mw = 9.0). In my previous research, I studied soil behavior during the Tohoku earthquake based on… read more here.
