What is seismicity?
Causes of earthquakes
- Tectonic: These earthquakes arise from the movement of the tectonic plates that make up the Earth's crust, impact large regions and are the main cause of most seismic events.
- Volcanic: This phenomenon is rare; when an eruption occurs with great intensity, it produces significant shocks that impact mainly the surrounding areas; however, its area of influence is limited compared to those caused by tectonic activity.
- Sinkings: The erosive effects of groundwater acting within the crust create voids, which eventually collapse under the weight of the overlying material. This collapse gives rise to vibrations known as earthquakes, which are infrequent and of minimal extent.
- Landslides: The immense weight of mountains exerts a significant force that can cause them to flatten and can trigger earthquakes through the occurrence of landslides along faults, however, these events are not usually of considerable magnitude.
