A series of earthquakes struck Mexico, with the largest a magnitude 5.2 event 69 km SW of Puerto Madero. USGS also reported four additional tremors between M4.2 and M4.4 in the region.
What to watch next: Continued monitoring of seismic activity in southern Mexico by the USGS following these recorded earthquakes.

Mexico Earthquake Cluster Includes 5.2 Magnitude Tremor Near Puerto Madero

The USGS has recorded five earthquakes in southern Mexico ranging from magnitude 4.2 to 5.2 over a short period, with the strongest measuring M5.2 located 69 km SW of Puerto Madero at a depth of 44.9 km. [2]

Multiple Earthquakes Strike Southern Mexico

The USGS recorded five earthquakes in southern Mexico. [1] [2] These events ranged in magnitude from 4.2 to 5.2. [2] [1] [3] [4] [5] The strongest of the events measured magnitude 5.2. [2] All five earthquakes took place along Mexico's southern Pacific coast region. [1] [2] [3] [4] [5] The cluster included one magnitude 5.2 earthquake along with four additional tremors. [2] [1] [3] [4] [5] Each event was documented separately by the USGS. [1] [2] [3] [4] [5]

Details of the M5.2 Quake

A magnitude 5.2 earthquake struck 69 km SW of Puerto Madero at a depth of 44.9 km. [2] This event represents the largest in the recorded cluster. [2] The location places the epicenter 69 km southwest of Puerto Madero. [2] The depth for this tremor reached 44.9 km. [2] The USGS identified this as a magnitude 5.2 earthquake. [2] This quake occurred as part of the series of events in southern Mexico. [2]

Additional Tremors Recorded

A magnitude 4.4 earthquake occurred 10 km E of El Bajío at a depth of 116.3 km. [1] A magnitude 4.4 earthquake struck 47 km WSW of Aquiles Serdán at a depth of 39.9 km. [4] A magnitude 4.3 earthquake was recorded 58 km SW of Brisas Barra de Suchiate at a depth of 35.0 km. [3] A magnitude 4.2 earthquake hit 131 km SW of Puerto Madero at a depth of 40.9 km. [5] These four events accompanied the larger magnitude 5.2 tremor. [1] [3] [4] [5] Each of the additional tremors was documented by the USGS with specific magnitude, location and depth details. [1] [3] [4] [5] The magnitudes of these four events stayed between 4.2 and 4.4. [1] [3] [4] [5]

Seismic Activity Overview

All five earthquakes occurred in proximity along Mexico's southern Pacific coast region. [1] [2] [3] [4] [5] The events included the magnitude 5.2 earthquake 69 km SW of Puerto Madero at 44.9 km depth. [2] They also included the magnitude 4.4 earthquake 10 km E of El Bajío at 116.3 km depth. [1] The magnitude 4.4 earthquake 47 km WSW of Aquiles Serdán reached 39.9 km depth. [4] The magnitude 4.3 earthquake 58 km SW of Brisas Barra de Suchiate occurred at 35.0 km depth. [3] The magnitude 4.2 earthquake 131 km SW of Puerto Madero took place at 40.9 km depth. [5] The USGS recorded each of these five earthquakes as separate events. [1] [2] [3] [4] [5]

No Immediate Reports of Damage

The USGS data for these moderate quakes contains no information on impacts. [1] [2] [3] [4] [5] No damage details appear in the records for the magnitude 5.2 earthquake. [2] The records for the magnitude 4.4 earthquake 10 km E of El Bajío likewise show no impact information. [1] The magnitude 4.4 earthquake 47 km WSW of Aquiles Serdán and the magnitude 4.3 earthquake 58 km SW of Brisas Barra de Suchiate also lack any reported effects in the USGS entries. [4] [3] The magnitude 4.2 earthquake 131 km SW of Puerto Madero follows the same pattern with no damage noted. [5]

What to watch next: Continued monitoring of seismic activity in southern Mexico by the USGS following these recorded earthquakes.
