The earthquake in Acapulco, Mexico was caused by movement along the Cocos and North American tectonic plates. These two plates are constantly moving and when they slip or collide, it can result in an earthquake.
Earthquakes of this magnitude (7.0) are considered rare in Acapulco, Mexico. However, the region is known for its high seismic activity due to its location near the Pacific Ring of Fire, where tectonic plates are constantly shifting.
The potential damage from a 7.0 magnitude earthquake can vary depending on the location and the strength of the structures in the affected area. In Acapulco, Mexico, buildings and infrastructure may have sustained significant damage, and there is also a risk of landslides and tsunamis in coastal areas.
Scientists use a device called a seismograph to measure the magnitude of an earthquake. This instrument records the seismic waves produced by the earthquake and calculates its strength based on the amplitude and frequency of the waves.
Currently, there is no reliable way to predict exactly when and where an earthquake will occur. However, scientists can monitor seismic activity and identify areas with a higher risk of earthquakes. It is important for communities in these areas to have emergency preparedness plans in place.
