Fig. 8From: Rapid estimation of tsunami earthquake magnitudes at local distance(Upper) The finite fault models (U. S. Geological Survey 2020) used to test proposed magnitudes. The five tsunami earthquakes were assumed to occur off Tohoku, Japan. On each map, the circle indicates the epicenter. The various magnitudes were estimated (Table 2) for synthetic records calculated with these fault models. (Lower) Source time function of each eventBack to article page
