Fig. 3.

Maps indicating (left) the locations and global Centroid Moment Tensor (gCMT) focal mechanisms of interplate thrust events probably located on the megathrust along the Sumatra-Andaman subduction zone, colored by centroid depth and with symbol size scaled linearly with seismic moment over the range Mw 5.0 to 9.2, and (right) differences in seismic magnitudes mbMw for these events, with symbol sizes scaled linearly with seismic moment. The magnitude differences have been corrected for corner frequency scaling with seismic moment using an ω-squared source model. The mb values are from the USGS PDE bulletin and the Mw values are from the gCMT catalog. The data are plotted at the gCMT centroid locations.
