The devastating tsunami produced by the Sumatra–Andaman earthquake (Mw 9.2) of 24 December 2004 heightened the interest of the scientific community in tsunami early warning systems. Global efforts have been successful in achieving a robust ocean basin‐wide tsunami warning in which there is enough time to obtain accurate source parameters, determine the tsunami potential, model the tsunami propagation through the oceans, and update it with real‐time sea‐surface height observations. However, local systems are still not reliable. In such cases, rapid estimation of accurate source parameters that are expeditious in discriminating a tsunamigenic earthquake and its potential tsunami are...
