The Papua New Guinea (PNG) tsunami of July 1998 was a seminal event because it demonstrated that relatively small and relatively deepwater Submarine Mass Failures (SMFs) can cause devastating local tsunamis that strike without warning. There is a comprehensive data set that proves this event was caused by a submarine slump. Yet, the source of the tsunami has remained controversial. This controv...

In this paper, work was carried out to simulate three-dimensional (3-D) tsunami run-up from high resolution remote sensing satellite data of QuickBird. In doing so, the tsunami wave spectra are extracted from QuickBird data using two dimensional di Fourier transform (2-DFFT). The tsunami propagation equation was then solved based on the standard Galerkin finite element approach to simulate 3-D ...

The tsunami source of the 2016 Fukushima Earthquake, which was generated by a normal faulting earthquake mech‐ anism, is estimated by inverting the tsunami waveforms that were recorded by seven tide gauge stations and two wave gauge stations along the north Pacific coast of Japan. Two fault models based on different available moment tensor solutions were employed, and their locations were const...

Recent results are presented to illustrate how predictions of tsunami wave impact and tsunami warning messages can be improved by including information about multiple, large-amplitude wave arrivals over longer time durations and at refined spatial resolution. A deployment of ocean bottom seismometers off the coast of southern California recorded the March 2011 Tohoku tsunami on 22 differential ...

natural hazard need not become a human disaster if society learns and applies lessons in preparation and resilience. Earthquake history speaks well to this—engineered structures need to stand up to strong shaking. Chile learned this lesson before its 2010 earthquake of magnitude 8.8. Because it had already enforced seismic provisions of building codes, there was little loss of life due to damag...
