Fig. 6: Earthquake magnitude reconstructions.
From: Cascading hazards of a major Bengal basin earthquake and abrupt avulsion of the Ganges River
Reconstructions of earthquake magnitude drawn from global datasets relating to (a) distance39 and (b) dike width37 suggest at least a ~M 6.5 and likely a ~M 7.0–8.0 paleo-event. The red zones indicates the minimum magnitude values based on the range of potential distances to the two likely source areas (Shillong Massif at 200–300 km, and the Indo-Burman subduction zone at 180–280 km) and widths (0.3–0.4 m) of the two primary dikes. The pink zones indicate typical values for the observed ranges.
