... intraplate regions, has generated large earthquakes associated with both these types of structures. The moderate earthquake that occurred on 21 May 2014 ( M w 6.1) in the northern Bay of Bengal followed an alternate mechanism, as it showed no clear association either with active or extinct ridge‐transform...

... that the 2014 Bay of Bengal earthquake, along with two other recent events in the region, were high‐stress‐drop events. It is possible that inferred high stress drops of the earthquakes analyzed in this study are in part a consequence of source depth. The estimated source depth of the 2014 earthquake is 60–85...
