The Mw 7.8 Mentawai earthquake of 25 October 2010 was a tsunami earthquake. It occurred seaward of the southern Mentawai islands of Sumatra, Indonesia, and preceded a very large tsunami that caused substantial damage and 509 deaths [casualty information from Pusdalops PB Sumbar (the Disaster Management Operational Control Center for West Sumatra Province)]. Maximum measured tsunami runup was >16 m. Seismological solutions indicate a shallow dip, consistent with an origin on the Sunda megathrust... Along the west coast of the Mentawai Islands, from southern Siberut to the southern tip of South Pagai Island, tsunami heights generally ranged from 1 to 10 m with the strongest effects observed along the west coasts of North and South Pagai islands. Maximum tsunami heights were measured along the western shores of a string of small islands west of South Pagai. On one of these islands, Sibigau, we recorded a maximum runup of 16.9 m, with similar measurements of 12.6, 14.8 and 10.2 m recorded at locations nearby. It should be noted that these values are measurements of true runup height, i.e., the situation where the tsunami wave reaches a maximum elevation against topographical relief.(ref #10265)
