Estimating Earthquake-Induced Tsunami Height Probabilities without Sampling

Estimating Joint Probabilities without Combinatory Counting

Computational Earthquake and Tsunami Research

U nderstanding and mitigating the effects of disasters requires the integration of research and practice in multiple science, engineering, technology, and social science fields to create a world that’s more resilient in terms of public safety, economic strength, and collective welfare. The January/February 2011 issue of CiSE explored hurricane prediction.1 Hurricanes are one of many natural dis...

Alternative Sampling Methods for Estimating Multivariate Normal Probabilities

We study the performance of alternative sampling methods for estimating multivariate normal probabilities through the GHK simulator. The sampling methods are randomized versions of some quasi-Monte Carlo samples (Halton, Niederreiter, Niederreiter-Xing sequences and lattice points) and some samples based on orthogonal arrays (Latin hypercube, orthogonal array and orthogonal array based Latin hy...

Recent massive earthquake and tsunami in Japan.

The 2011 Tohoku earthquake and devastating tsunami.

At 14:46 on March 11, 2011, the magnitude-9.0 earthquake attacked Sendai and neighboring cities distributed along the northeast coast of Honshu Island, Japan. Its epicenter is located 130 km east of Sendai (Fig. 1). Unfortunate ly, the strong earthquake generated devastating tsunamis that destroyed many towns and villages near the seashore in Iwate, Miyagi, and Fukushima prefectures. The natura...
