Earthquakes inside volcanoes are a result of processes of rock fracture, gases, and magmatic fluids.
Volcanologists of the Geophysical Institute of Peru (IGP) of the Arequipa headquarters, who monitor in real time the activities of the volcanoes Misti, Sabancaya, Ticsani, and Ubinas, recorded and plotted, during 2017, thousands of earthquakes in the vicinity of these active massifs.
“According to the IGP, the active volcanoes of Peru, four of them monitored in real time, experience thousands of earthquakes inside as a result of processes of rock fracture, movement of gases and magmatic fluids, the rise of magma, among others”, said La República.
With the information from earthquakes that occurred in the volcanoes during 2017, professionals of the IGP headquarters in Arequipa created 3D maps that show the distribution in depth of these events.
The Geophysical Institute of Peru ensures that these tools are extremely useful in Disaster Risk Management (DRG), since they graph the evolution of the seismicity under the volcano and how it migrates in the vicinity of the volcanic structure, informed La República.
One of the reasons why Peru is constantly affected by earthquakes is because of its location on the Ring of Fire in the Pacific. This is what people have named an area in the basin of the Pacific Ocean where volcanoes constantly erupt and quakes take place very often.
