Abstract
Using the example of two tsunamigenic earthquakes, a method for determining the magnitude of the displacement of the seabed, which is the cause of the tsunami, is being worked out. It is shown that with an average coefficient of divergence of deformation anomalies recorded by a laser strainmeter for the entire planet, it is possible to approximately estimate the amount of displacement of the seabed at the site of tsunami formation. For each region where the tsunami originated, there are more accurate divergence coefficients that can be estimated experimentally and from which the values of seabed displacements can be more accurately determined.
