Several people rushed out of their houses after they felt tremors. There were also reports of electric outages in several parts of the city.

"Earthquake off Chiapas, Mexico. Felt it all the way here in Playa Del Carmen. Tsunami warning for southern Pacific coasts", said James R.D. Scott on Twitter. 

Mexico is located on top of three large tectonic plates, making it prone to earthquakes. North America, South America, Nazca, and Cocos are the four major tectonic plates involved in causing this earthquake. It is predicted to be as massive as the 1995 and 1985 Mexico earthquakes. The earthquake has been felt as far as Austin, Texas.

However, bad-times for Mexico is not over, it seems. There is also a possibility of Katia, a Category 1 hurricane, hitting Mexico soon, says the National Hurricane Centre of Mexico. It is about 300 Km south-east of Tampico and has sustained winds of 140 km/hr.
