In connection with a series of earthquakes in the area of the Mayon volcano, located in the southeast of the main Philippine island of Luzon, the Philippine Institute of Volcanology and Seismology raised the level of danger to one.
On Monday, experts recorded 25 volcanic earthquakes. The total number of tremors in the region of the mountain in the last days was 91.
In addition, there is an increased release of sulfur dioxide. Experts note that these factors indicate a possible approach of a volcanic eruption.
The 6-kilometer radius around the mountain is considered unsafe for humans.
Parameters directly related to eruptions include earthquakes, gas emissions, dome growth, glow of the crater, lava flow, pyroclastic flows and ash emissions. Specialists continue to monitor the volcano.
