Assessment of Site Response to Long Distance Sumatra Earthquakes
ABSTRACT – Singapore is a city state island located off the southern tip of Malaysia Peninsula. Although Singapore is located in a low seismicity area with mild winds, it is a classic example of low seismic hazard and high exposure scenario. It is about 400 km away from a highly active earthquake belt comprising the Sumatra fault and the subduction zone. The response of a building to long-dista...
متن کاملImplications of the 26 December 2004 Sumatra–Andaman Earthquake on Tsunami Forecast and Assessment Models for Great Subduction-Zone Earthquakes
Results from different tsunami forecasting and hazard assessment models are compared with observed tsunami wave heights from the 26 December 2004 Indian Ocean tsunami. Forecast models are based on initial earthquake information and are used to estimate tsunami wave heights during propagation. An empirical forecast relationship based only on seismic moment provides a close estimate to the observ...
متن کاملAsteroid Impact Tsunami: A Probabilistic Hazard Assessment
We investigate the generation, propagation, and probabilistic hazard of tsunami spawned by oceanic asteroid impacts. The process first links the depth and diameter of parabolic impact cavities to asteroid density, radius, and impact velocity by means of elementary energy arguments and crater scaling rules. Then, linear tsunami theory illustrates how these transient cavities evolve into vertical...
متن کاملTsunami inundation modeling for western Sumatra.
A long section of the Sunda megathrust south of the great tsunamigenic earthquakes of 2004 and 2005 is well advanced in its seismic cycle and a plausible candidate for rupture in the next few decades. Our computations of tsunami propagation and inundation yield model flow depths and inundations consistent with sparse historical accounts for the last great earthquakes there, in 1797 and 1833. Nu...
متن کاملComparisons of dynamic triggering near Beijing, China following recent large earthquakes in Sumatra
[1] Dynamic triggering around the Fangshan Pluton near Beijing is repeatedly identified. Here we report clear triggered events in this region during the surface waves of the 2012 Mw8.6 Sumatra earthquake. However, we do not find any triggered events during the G2 waves of the Mw8.6 event, and the surface waves of the Mw8.2 Sumatra earthquake that occurred two hours later. The peak ground veloci...
