The Wharton Basin earthquake sequence on April 11, 2012, offshore Sumatra, represents the two largest (Mw > 8.0) strike-slip earthquakes ever recorded. Ground fault displacements generated a spectrum of acoustic-gravity waves due to solid Earth–atmosphere coupling. Wave-like perturbations in Tota...
