Earthquakes Strike South of Belen: Understanding Magma Body Activity

The region south of Belen, New Mexico, has experienced a series of nine earthquakes in the early morning hours, with the largest measuring 3.8 magnitude.

The earthquakes were followed by a second round of activity later in the afternoon, demonstrating the ongoing presence of seismic energy beneath the surface.

Residents of Veguita, a small town in the area, reported feeling the earth shake, with some describing it as a 'whole house' shaking event.

'When I got up this morning at about 3:53 a.m., that's when that first one happened,' said Veguita resident Alberto Thomas. 'Just like the whole house started shaking, and I was like, 'Whoa, my God.' And told mom, 'The house is shaky.'

Experts say these earthquakes are linked to a body of magma located about 12 miles beneath the surface, spanning an impressive 1,300 miles.

'So with magma bodies, it's pretty common to get earthquakes happening in these swarms where you have several earthquakes happening in a short period of time, like what we're seeing now,' explained Mairi Litherland, of the Albuquerque Seismological Lab with the USGS.

The recent activity is typical for this type of geological feature, which slowly inflates and causes stress in the crust.

'This magma body is very slowly inflating. And so that causes stress in the crust that can, over a long period of time, cause the slip on the earth on the faults that causes earthquakes,' Litherland added.

Prompting questions about the likelihood of a more significant seismic event in the region, Litherland emphasized that while a catastrophic earthquake is possible, it is considered unlikely.

'In 1906, in another near Socorro, there was a magnitude six earthquake. So that was a century ago. We don't get those big earthquakes very often, but it is possible. So I wouldn't say worry,' Litherland said.

Residents are advised to be prepared for any seismic activity, knowing what to do in case of an earthquake: 'drop, cover, and hold on.'

This approach ensures individuals, especially those in areas prone to seismic activity, prioritize their safety by taking quick action in response to an earthquake.

Considering the region's history and the ongoing seismic activity, there's an increased focus on understanding the complex interplay between tectonic activity and surface-level events.

The recent earthquakes serve as a reminder of the intricate relationship between geological forces and the dynamic nature of Earth's surface.

Understanding this relationship allows us to better appreciate the complexities beneath our feet and anticipate potential risks and consequences of seismic activity.

Earthquake preparedness, combined with a deeper awareness of local geological dynamics, can help mitigate the impact of seismic events on communities.

As scientists continue to monitor this region and other areas of seismic activity, there's a growing need to advance our knowledge and predictive capabilities, ensuring more informed responses to seismic threats.

The recent earthquakes demonstrate the importance of vigilance, preparedness, and collaboration between experts and the general public in coping with Earth's dynamic forces.
