Was there active tsunami generation during 28 March 2005 Sumatraearthquake?

摘要

When the 8.7 magnitude (March 2005) earthquake (epicentre, 2.074 degree N, 97.013 degree E) occurred in the Indian Ocean (near the position of 26 December 2004 giant earthquake, epicentre: 3.316 degree N, 95.854 degree E) in northern Sumatra, the world anxiously awaited word of yet another devastating tsunami similar to the earlier one. There was, however, a vast difference. The tsunami warnings were issued in India by India Meteorological Department, quickly in anticipation and were as quickly withdrawn officially. The question arises whether there was a tsunami generation on this occasion? This correspondence looks into some of the differences and the conclusions based on a computer simulation using the TOAST model.
