Original Story:

An 8.2-magnitude earthquake hit Mexico late Thursday with a depth of 21 miles, the Pacific Tsunami Warning Center (PTWC) said, citing USGS data. The quake struck off the coast of Chiapas with its epicenter 76 miles southwest of the town of Pijijiapan, triggering a tsunami warning.  

Earlier, PTWC said the magnitude of the earthquake was 8.0. The PTWC said that hazardous tsunami waves could be expected within three hours following the quake along some coasts of Mexico, Guatemala, El Salvador, Costa Rica, Nicaragua, Panama, Honduras, and Ecuador. However, no tsunami warning was issued for the U.S. West Coast or British Columbia as a result of the quake. 

"It's a big quake. It's about 70 miles offshore, but it's not an unheard of the quake," USGS geophysicist Randy Baldwin told NBC News, adding: "This is a large quake. I'm sure that it will be widely felt and possibly damaging." There were no immediate reports of major damage.

The quake forced many people in the capital Mexico City to run outside of their homes into the streets, Reuters reported. 

"The shaking along the coast of Chiapas at this point is estimated to be very strong to severe," Jana Pursely, a geophysicist at the USGS told CNN. "I would expect damage along the coast of Chiapas."

Mexico's President Enrique Pena Nieto wrote on his Twitter account: "Civil protection protocols are activated, including the National Emergency Committee."

According to Mexico’s civil protection agency, late Thursday's quake was the strongest to hit the country since a devastating 1985 tremor that affected several buildings and killed thousands.

Mexico is currently being threatened on its eastern coast by Hurricane Katia which has now become a category one hurricane.
