Was the 1941 Andaman earthquake tsunamigenic? Comments on 'Inundation studies for Nagapattinam region on the east coast of India due to tsunamigenic earthquakes from the Andaman region' by Srivastava et al. 2012

摘要

The question whether the 1941 Andaman earthquake did generate a damaging tsunami that impacted the islands and the eastern coast of India is not easily resolvable owing primarily to the non-availability of both instrumental and historical data. The available information on the 1941 Andaman earthquake is somewhat limited because of the dif?culties emanating from a war in which Andaman Island was part of eastern war theater. The recent paper by Srivastava et al. (2012) deals with modeling of inundation of the 1941 earthquake along the Nagapattinam Coast on the southeastern India, which implicitly assumed that the 1941 earthquake was indeed tsunamigenic. Our ?ndings, however, do not support such a supposition. Here, we present our arguments on the non-tsunamigenic status of the 1941 Andaman earthquake.
