An earthquake swarm is in progress at the Michoacan-Guanajuato volcanic field, Mexico. At this time, it's unclear whether the quakes are volcanic or tectonic in origin. The zone contains over 1 400 vents and covers an area of approximately 200 x 250 km (125 x 155 miles) in the states of Michoacan and Guanajuato. The last known eruption in this region took place at Paricutin volcano from February 20, 1943 - February 25, 1943 (VEI 4).

The center of the crisis is near the town of Uruapan (population 315 000), the second-largest town in the state of Michoacan. The town is located at the western edge of the Purépecha highlands, just to the east of the Tierra Caliente region.

According to the CENAPRED, more than 1 800 earthquakes were recorded since January 5, 2020. The largest were two M4.1, registered on January 23 and 30. The agency has sent teams to conduct further surveys and identify the source of seismicity.

Despite the number of earthquakes, there are no reports of damage.

The distribution of seismicity shows that it develops at a depth of about 40 km (25 miles), which roughly corresponds to the thickness of the crust in the area. In the past, several similar swarms of purely tectonic origin were recorded in the area, with the most recent in 2006.

Big burrito! In 1995 Ridgecrest had a swarm of over 2500 quakes and next swarm started in July 2019 and is still going on continuously.

More than 80,000 earthquakes have been recorded in the Ridgecrest area since July 4 — the aftermath from two of the biggest temblors to hit California in nearly a decade.
Funny how it's dropped out of the news, China Lake was a really big story within the story and it's gone hush too.
