MEXICO CITY: An earthquake of magnitude 8.1 struck off the southern coast of Mexico, the U.S. Geological Survey (USGS) said, killing at least six people and triggering small tsunami waves but no major destruction.
The quake was apparently stronger than a devastating 1985 tremor that flattened swathes of Mexico City and killed thousands, but this time damage to the city was limited.
A number of buildings suffered severe damage in parts of southern Mexico. Some of the worst initial reports came from Juchitan in Oaxaca state, where sections of the town hall, a hotel, a bar and other buildings were reduced to rubble.
Rescue workers labored through the night in badly affected areas to check for people trapped in collapsed buildings.
Windows also shattered at Mexico City airport and power went out in several neighborhoods of the capital, affecting more than 1 million people. The cornice of a hotel came down in the southern tourist city of Oaxaca, a witness said. The tremor was felt as far away as neighboring Guatemala.
The epicenter of the quake was in the Pacific, 54 miles (87 km) southwest of the town of Pijijiapan in the poor southern state of Chiapas, 43 miles deep. Four people were killed in the state, Governor Manuel Velasco said. Two children were killed in neighboring Tabasco state, Governor Arturo Nunez said.
The quake triggered waves as high as 2.3 ft (0.7 m) in Mexico, the Pacific Tsunami Warning Center said. Mexican television showed images of the sea retreating about 50 meters, and authorities evacuated some coastal areas.
“The tsunami risk on the Chiapas coast does not represent a major risk, it’s not very big, it’s not a major worry,” President Enrique Pena Nieto said in a call to TV network Televisa.
The president said more aftershocks were likely and that people should carefully check their homes and offices for structural damage and for gas leaks. “We are alert,” he said.
The USGS reported multiple aftershocks, ranging in magnitude from 4.3 to 5.7.
Classes were suspended in most of central and southern Mexico on Friday to allow authorities to review damage.
There was no tsunami threat for American Samoa and Hawaii, according to the U.S. Tsunami Warning System. The national disaster agency of the Philippines put the country’s eastern seaboard on alert, but no evacuation was ordered.
People in Mexico City, one of the world’s largest cities, ran out into the streets in pyjamas and alarms sounded after the quake struck just before midnight, a Reuters witness said.
Helicopters buzzed overhead a few minutes later, apparently looking for damage to buildings in the city, which is built on a spongy, drained lake bed.
