(Strange Sounds) – 3 volcano-tectonic quakes were recorded at Zambales province within the last 24 hours. And we all know that Mount Pinatubo is the only active volcano in this province… So? Is it preparing its next big blast?
A Magnitude 4.4 earthquake first struck 16 km northeast of Olongapo City at a depth of 10 km. The first quake was followed by a Magnitude 3.2 in the same area, approximately 12 km northeast of Olongapo city at a depth of 6 km.
Finally, the last M4.3 earthquake occurred on August 12, 2020, at 10:47 AM 13 km southeast of Olongapo City, Zambales at a depth of 9 km. A volcano-tectonic earthquake is a tremor caused by the movement of magma beneath the surface of the Earth.
The movement results in pressure changes where the rock around the magma has experienced stress. At some point, this stress can cause the rock to break or move. This seismic activity is used by scientists to monitor volcanoes. So is Pinatubo preparing for the next eruption?
