Seismic activity refers to the occurrence of earthquakes and other ground vibrations caused by the movement of tectonic plates in the Earth’s crust. It is measured by instruments called seismometers, which detect and record the intensity, duration, and frequency of these seismic waves. Seismic activity can vary significantly in terms of magnitude, ranging from minor tremors that may not be felt by people to major earthquakes that can cause widespread destruction. Monitoring seismic activity is crucial for understanding geological processes, assessing earthquake risks, and implementing safety measures in earthquake-prone regions. The study of seismic activity also contributes to insights into the Earth’s internal structure and tectonic dynamics.
A 3.7 magnitude earthquake occurred near Palma del Río, its epicenter 7 km from Cazalla de la Sierra, Sevilla. The tremor, almost imperceptible, was felt in nearby villages like San…
