The Philippine Institute of Volcanology and Seismology (Phivolcs) made it clear that the 6.6 magnitude earthquake that shook Cotabato and its surrounding areas is not an indication of any volcanic activity.
A 6.6 earthquake with a depth of just seven kilometers, struck Mindanao at 9:04 am on Tuesday, October 25, with the epicenter located 25 kilometers southeast of Tulunan, Cotabato. It was the second shake that hit Tulunan in about two weeks.
After the shaking, various posts from netizens circulated online, warning people that Mount Apo is expected to explode after two previous earthquakes.
Photos of the assumed magma near the mountain also went viral.
But Phivolcs also said that the closest active volcanoes from the epicenter in Tulunan are Matutum Volcano and Parker Volcano, the latest and subsequent earthquakes "being tectonic in origin."
It assured the public that "as part of DOST-Phivolc's monitoring procedures for moderate to large earthquakes. Occurring near active volcanoes, the Institute will closely monitor earthquake events in relation to any activity that may be associated with the Matutum and Parker volcanoes."
Some netizens also clarified that the supposed magma is actually a "float" or a normal occurrence of any intense earthquake, saying that it is only a saturated earth that loses its strength and stiffness in response to an applied stress such as shaking during an earthquake .
Phivolcs-Davao Scientific Research Assistant Chris Vidad said their offices have also reported no volcanic activity in Mount Apo, which lies between Davao City and Davao del Sur Province and Cotabato.
Even though Mount Apo is a At the large solar fanatic, potentially active stratovolcano, Vidad said that Phivolcs has not noticed any activities that would indicate its possible eruption.
"Although di natin masabi na may correlate siya ngayon doon said recently paglindol dahil ang focus namin is more at fault, we" are closely monitoring Mount Apos's operations (although we cannot tell that it has a recent earthquake correlation time because our main focus is on bugs, we are closely monitoring Mount Apos activity), "Vidad said in a telephone interview.
He added that Phivolcs are also monitoring the mountain, as there are bugs that are slowly found nearby. He added that they are still determines the path of error to see if they are linked to Mount Apo.
Vidad advised the public to refrain from sharing unverified news and said it would cause general panic.
Mount Apo is the highest mountain in the Philippines, with a elevation of 2,954 meters (9,692 feet) above sea level.The summit overlooks the city of Davao 45 kilometers northeast, Digos 25 kilometers southeast and Kidapawan 20 kilometers west.
Phivolcs said aftershocks are expected to occur in the coming days or weeks.
