Socorro has been jiggling for more than 10 days with a swarm of earthquakes, seismologists said Monday, Aug. 31.

"People are feeling them and hearing them," said Rick Aster, a professor at the New Mexico Institute of Mining and Technology in Socorro who is helping track the earthquake swarm.

Tech's instruments have detected about 80 quakes since the first was felt Aug. 19.

No damage has been reported, said Sue Bilek, a New Mexico Tech seismologist who has been monitoring the quakes. All of the quakes had magnitudes less than 3, according to Bilek.

The quakes have been centered in an area several miles north and east of Socorro.

Socorro sits atop a large body of molten magma more than 10 miles below Earth's surface. As a result, the region sees almost half of New Mexico's significant earthquakes.

While quake swarms in the area are common, this is the largest in the past decade, according to Aster.

The area's largest recorded earthquake was an estimated 6.5 magnitude in 1906, which caused significant damage.

While Socorro is the epicenter of New Mexico's earthquake activity, quakes have been felt up and down the Rio Grande rift, an area where Earth's crust is slowly spreading apart, sometimes creating earthquakes in the process.

Bilek said the latest swarm is no cause for alarm, because previous swarms have never led to major quakes.
