Features of Tsunami Occurrence by the 1983 Nihonkai-Chubu Earthquake, especially the Relationship between Tsunami Occurrence and Earthquake Mechanism

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...

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...

Statistical Features of Earthquake Temporal Occurrence

The physics of an earthquake is a subject with many unknowns. It is true that we have a good understanding of the propagation of seismic waves through the Earth and that given a large set of seismographic records we are able to reconstruct a posteriori the history of the fault rupture (the origin of the waves). However, when we consider the physical processes which lead to the initiation of a r...

Detailed analysis of tsunami waveforms generated by the 1946 Aleutian tsunami earthquake

The 1946 Aleutian earthquake was a typical tsunami earthquake which generated abnormally larger tsunami than expected from its seismic waves. Previously, Johnson and Satake (1997) estimated the fault model of this earthquake using the tsunami waveforms observed at tide gauges. However, they did not model the second pulse of the tsunami at Honolulu although that was much larger than the first pu...
