Deformation method of tsunami prediction

Abstract

Based on the analysis of numerous data on variations of deformations of the Earth’s crust obtained using a laser strainmeter, deformation anomalies (deformation jumps) that occur during tsunami generation have been detected. The deformation jumps recorded by the laser strainmeter are caused by bottom movements leading to the formation of a tsunami. According to the data of many registered tsunamigenic earthquakes, the attenuation coefficients of the identified deformation anomalies for four regions of the planet have been calculated.
