Empirical Green’s functions for tsunamis

For first time, we developed empirical Green’s functions for tsunamis. The details are shown in the figure. There were two tsunamis in the Solomon Islands region in July 2015 (Mw7.0) and in February 2013 (Mw8.0; known as the Santa Cruz tsunami). The sources of the two tsunamis are very close to each other (see asterisks in […]

A new source model for the 27 November 1945 Makran tsunami

A new source model has been recently published by Heidarzadeh and Satake (2014) for the Makran tsunami of 27 November 1945. To propose this source, all available data including tide gauge records at Mumbai (India) and Karachi (Pakistan), coastal deformation data along Pasni and Ormara (Pakistan) as well as inferred sea level oscillations at Port […]
