Abstract
We are using data for two tsunamigenic earthquakes to develop a procedure for determining the displacement of sea bottom giving rise to tsunamis. We show that, assuming an average geometrical spreading factor for strain anomalies recorded by a laser strainmeter worldwide, we can find an approximate estimate of sea bottom displacement at a tsunamigenic site. There are more accurate spreading factors for each region where tsunamis have been generated; these can be estimated experimentally to be used for more accurate determination of sea bottom displacements.
期刊介绍：
Journal of Volcanology and Seismology publishes theoretical and experimental studies, communications, and reports on volcanic, seismic, geodynamic, and magmatic processes occurring in the areas of island arcs and other active regions of the Earth. In particular, the journal looks at present-day land and submarine volcanic activity; Neogene–Quaternary volcanism; mechanisms of plutonic activity; the geochemistry of volcanic and postvolcanic processes; geothermal systems in volcanic regions; and seismological monitoring. In addition, the journal surveys earthquakes, volcanic eruptions, and techniques for predicting them.
