Tsunami Threat for Pacific coasts of Mexico, Central America

Post Reply New Topic

Minutes ago, a tsunami threat was issued by the National Weather Service's (NWS) Pacific Tsunami Warning Center for the Pacific coasts of Mexico, Guatemala, El Salvador, and Honduras.

The United States Geological Survey (USGS) said the quake had a preliminary magnitude of 7.4 and struck around 11:29 a.m. ET, 7 miles west of Santa María Zapotitlán, Mexico. The temblor had a depth of about 20 miles and was centered along the Pacific coast of Oaxaca state, near the resort of Huatulco.



"Hazardous" tsunami waves from the quake are possible within 620 miles of the epicenter along the Pacific Coast.

My own thoughts is that a 7.4 magnitude is rather weak to produce a great tsunami. But it might produce some large waves along the coast.
