Megathrust faults host the largest earthquakes on Earth, which can trigger cascading hazards such as devastating tsunamis. Determining characteristics that control subduction-zone earthquake and tsunami dynamics is critical to mitigate megathrust but impeded by structural complexity, large spatio-temporal scales scarce or asymmetric instrumental coverage. Here we use high-performance computing ...

Tsunami generation by an earthquake is generally modeled by water surface displacement identical to the vertical deformation of ocean bottom due to faulting. The effect of horizontal deformation is usually neglected. However, when the tsunami source is on a steep slope and the horizontal displacement is large relative to the vertical displacement, the effect becomes significant. We show this fo...

Aceh is located on the Indian Ocean Coast which very prone to Tsunamis, this due frequent large earthquakes Megatrust faults, such as those that occurred during earthquake December 26, 2004. Based 2012 earthquake, Acehnese prefer horizontal evacuation vertical [1]. In case, many people in Banda do not believe strength of TVE buildings (distrust building). From research, it possible for will sam...

Bridge structures along the coasts are often subjected to hydrodynamics loads of various forms and intensities. The most dramatic loads are those due to tsunamis and storm surges as vividly demonstrated by images of the Dec. 2004 Indian Ocean Tsunami and the Sept. 2005 Katrina Hurricane in the Gulf of Mexico. Other loads include wave impact, current induced scour, and floating debris impact. Th...

This paper assesses the structural performance of RC frame buildings subjected to tsunami-induced loads, accounting for influence exterior masonry infill walls on overall performance. Both in-plane and out-of-plane contributions are considered in analysis. To illustrate importance response structures tsunami, two case study modelled 3D. The first is a typical two-storey school building Sri Lank...

[1] The enormously destructive tsunami of December 2004, caused by sudden motion of the Sunda megathrust beneath the Indian Ocean, raised concerns about tectonically induced tsunami worldwide. Submarine landslides may also trigger dangerous tsunami. However, the potential and repeat time for such events is in most places poorly known due to inadequate exploration of the sea floor and age constr...

The Northern Indian Ocean is unique in the global ocean because of seasonal reversal of winds as well as surface ocean currents. In the southern part of the Indian Ocean, a significant ocean-atmospheric phenomenon developed just like an El Nino phenomenon noticed in the Pacific Ocean. This phenomenon is known as the Indian Ocean Dipole. In this study we investigate the relationship between IOD ...
