By Mike Crismundo BUTUAN CITY – A series of tectonic earthquakes continued to rattle residents in Siargao with 14 tremors recorded by the Philippine Institute of Volcanology and Seismology (Phivolcs) on Monday. The series of earthquakes that struck Siargao Island, in Surigao del Norte province did not inflict damage or injury. But rescue teams and personnel of the municipal and provincial disaster risk reduction and management councils (DRRMCs) there were already ordered to be on “standby alert” in their respective command posts following the series of mild earthquakes that struck the island. Surigao del Norte Gov. Sol F. Matugas and province’s 1stDistrict Rep. Francisco Jose F. Matugas ll mobilized different action teams composed of local officials and medical teams. “Our respective disaster councils are already on alert since a 5.5 magnitude quake struck Siargao island last week,” said Rep. Matugas. Phivolcs said in its latest bulletin on Monday that the strongest earthquake that struck Siargao Island was a 3.7 magnitude earthquake and its epicenter was plotted 60 kilometers (km) southeast of Pacific Ocean facing town of General Luna, Siargao Island, Surigao del Norte, with a depth of 12 km. Aside from the 13 mild tectonic earthquakes that struck the country’s surfing capital town of General Luna, another 2.9 magnitude tremor was also registered at 4:51 a.m. on Monday (April 29) and its epicenter was traced 61 km southeast of that same town and island, with also a depth of 12 km, the state agency said. On Sunday (April 28), a 4.7 magnitude earthquake was recorded at 11:59 a.m. and its epicenter was located 50 km southeast of that same town and island, with a depth of 14 km., Phivolcs also reported, in its bulletin. Last week (April 26), a 5.5 magnitude tremor was also recorded as its epicenter was pinpointed 64 km northeast of that same town and island, with a depth of 12 km. The series of tremors that struck Siargao island were all tectonic in origin and no tsunami alert was raised by the state agency. The Philippines lies in the Pacific “Ring of Fire”, where colliding plates in the Earth’s crust cause frequent earthquakes and volcanic activity.
