Preliminary simulation of Mexico tsunami

3-D Animation shows the land in the distance with slow rippling waves that roll towards the land and then start sloshing.

Detailed Description

Preliminary simulation of the tsunami from the September 8, 2017 M=8.1 intermediate-depth earthquake offshore of Chiapas, Mexico. Viewpoint looking to the northeast. The first 4 hours of propagation is shown. Look for the wave that reflects off the edge of the continental shelf and travels back toward shore.

Please note: the program used to create these simulations does not model nonlinear and breaking effects as waves travel into shallow water. Wave heights have been exaggerated to make details easier to see.
