Global Wave Propagation After 2004 Sumatra Event Titov, V., . Rabinovich, . Mojfeld, . Thomson, and . Gonzalez, The global reach of the 26 December 2004 Sumatra tsunami, Science, 309 (5743), 2045-2048, 2005. Massive EQ. 30-ft vertical displacement, 60-ft horizontal displacement. “This tsunami is the first for which there are high-quality worldwide tide-gauge measurements and for which there are multiple-satellite altimetry passes of tsunami wave height in the open ocean.” Combined with numerical model simulations to show global reach of initial event. Mid-ocean ridges help to guide the tsunami energy propagation, which means they were still super long wavelength and hence super deep.
