A magnitude-6.0 earthquake rocked an area between the southern Mexican states of Guerrero and Oaxaca on Monday, but no injuries have been reported, the Mexican Seismology Institute said.
The earthquake occurred at 12:36 p.m. at a depth of 12 kilometers (about 7.5 miles), the U.S. Geological Survey said.
The USGS put the earthquake’s strength at magnitude-6.3.
The temblor was less powerful than the magnitude-7.4 earthquake that occurred in March, the Mexican Seismology Institute said.
Monday’s quake was an aftershock from the March 20 temblor, which killed two people and was followed by dozens of aftershocks on the day it occurred, Mexican Seismology Institute spokesmen told Efe.
The epicenter of Monday’s earthquake was located 28 kilometers (17 miles) east of Ometepec and close to the epicenter of the March 20 quake.
Hospitals and essential services are operating normally, officials said, adding that an aerial inspection did not reveal any damage to structures in Ometepec.
Mexico, one of the countries with the highest levels of seismic activity in the world, sits on the North American tectonic plate and is surrounded by three other plates in the Pacific: the Rivera microplate, at the mouth of the Gulf of California; the Pacific plate; and the Cocos plate.
That last tectonic plate stretches from Colima state south and has the potential to cause the most damage since it affects Mexico City, which has a population of 20 million and was constructed over what was once Lake Texcoco.
The magnitude-8.1 earthquake that hit Mexico City on Sept. 19, 1985, was the most destructive to ever hit Mexico, killing some 10,000 people, injuring more than 40,000 others and leaving 80,000 people homeless.
The most recent powerful quake to hit Mexico was a magnitude-7.6 temblor that rocked Colima on Jan. 21, 2003.
