... Abstract Tsunami hazard maps are generated for the coastline of the Mentawai Islands, West Sumatra, Indonesia, to support evacuation and disaster response planning. A random heterogeneous slip generator is used to forward model a suite of earthquake rupture scenarios on the Mentawai Segment...

... fault zone, that we called the Mentawai fault zone, located in the fore-arc area just east of the Mentawai Islands; it is at least 600 km long. Thus, the Sumatra sliver plate appears to be composed of several strips that move toward the northwest to accommodate the oblique subduction. Geological...

.... Ophiolite occurrences in Andaman and Mentawai islands belonging to the western belt are generally linked with active subduction west of the island arc. This subduction began only in late Miocene time, and thus it could not have produced the ophiolites, which had been emplaced on land much earlier...

...) for Southern Scotland is equally questionable since the Southern Uplands Fault (SUF) may show major normal or transcurrent movement. I suggest that better evidence is the nature of the respective rock successions, and this presents a very different picture. The Mentawai islands forming the non-volcanic...

... strain that had built up in the previous interseismic period, and slip in 1833 relieved more strain than was accumulated in the years since 1797 ( Natawidjaja et al. , 2006 ). Therefore, it is plausible that the segment along the Mentawai islands fails together in the future. Geodetic and paleogeodetic...
