Shaking was moderate to strong on land, reaching up to 35% g. This is high enough to cause significant damage in countries less prepared for quakes than Japan. In this blind test, Temblor’s ground motion and site amplification (SiteAmp) models matched the strong shaking well, as seen by comparing the top two panels, or in the scatter plot at bottom. For the prediction, Temblor used a point source with the magnitude, location and depth given by the USGS. Credit: Temblor, CC BY-NC-ND 4.0
