SUMMARY
The earthquake measuring 7.4 magnitude occurred on June 23, 2020, at 15:29:05 UTC, located 12 km SSW of Santa María Zapotitlán, Oaxaca, Mexico, at a depth of 26.3 km. This seismic event is attributed to the subduction of the Cocos plate beneath the North American plate, resulting in geological phenomena such as the formation of the Middle American trench and the Cordillera Neovolcánica volcanic region. The discussion highlights the impact of tectonic movements on the region's geology and the importance of monitoring seismic activity.
PREREQUISITES
- Understanding of tectonic plate movements, specifically the North American and Cocos plates.
- Knowledge of seismic measurement tools, such as seismometers.
- Familiarity with geological formations like subduction zones and volcanic arcs.
- Awareness of earthquake magnitude scales and their implications.
NEXT STEPS
- Research the geological implications of subduction zones in plate tectonics.
- Learn about the operation and calibration of seismometers for earthquake monitoring.
- Explore the characteristics and formation of the Cordillera Neovolcánica volcanic region.
- Investigate earthquake preparedness and response strategies in seismically active areas.
USEFUL FOR
Geologists, seismologists, emergency management professionals, and anyone interested in understanding the dynamics of earthquakes and volcanic activity in southern Mexico.
