Two hours ago a magnitude 7.2 earthquake struck near Galeana, Mexico.  It shook both the nearest city of substantial size, Tecpan, as well as the capital of Mexico city.  The latter is located on an old lake bed and is subject to amplified shaking due to the thick layer of sediments.

From the Hazard Viewer, it can be seen that the earthquake struck in an area of elevated probability:

We can draw a circle of radius 100 miles around the epicenter to compute the probability of the event (the probability calculations will next be updated tonight at midnight):
