Phivolcs Director Teresito Bacolcol(File photo) MANILA-As a magnitude 7.8 earthquake recently hit Turkiye and Syria, the head of the Philippine Institute of Volcanology and Seismology (Phivolcs) on Tuesday said such a magnitude is also likely to happen in the country. "There's always this possibility. In fact, it already happened on July 16, 1990. To recall, the 1990 Luzon earthquake is magnitude 7.8," Phivolcs Director Teresito Bacolcol said in a public briefing. Bacolcol added that the country has many active faults that are capable of generating magnitude 7.8 earthquake. Based on instrumental records, the 1990 Luzon earthquake is the strongest to hit the country, he continued. According to Phivolcs' website, the 1990 Luzon earthquake produced a 125 km-long ground rupture that stretches from Dingalan, Aurora to Kayapa, Nueva Vizcaya. The quake was caused by strike-slip movements along the northwest segment of the Philippine Fault Zone and its splay, the Digdig Fault
