摘要

我们正在利用两次引发海啸的地震的数据来开发一种程序，以确定引起海啸的海底位移。我们表明，假设全球激光应变仪记录的应变异常的平均几何扩展因子，我们可以在海啸发生地点找到海底位移的近似估计。海啸发生的每个地区都有更准确的传播因子；这些可以通过实验估计，用于更精确地测定海底位移。

The Pacific Tsunamigenic Earthquakes in the Early 2024

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.
