BAGUIO CITY: A quick but moderately strong quake measured at magnitude 4.1 jolted Benguet early Tuesday morning seeing most schools in the secondary and tertiary levels suspending classes for today. Baguio City Mayor Mauricio Domogan ordered the suspension of all classes as a precautionary measure as the Philippine Institute of Volcanology and Seismology (Phivolcs) traced the epicenter at 13 kilometers southeast of the city. The private-run Saint Louis University having more than 34,000 elementary, high school and college students also suspended classes in all levels for its Bonifacio, Assumption and Bakakeng campuses. University of the Cordilleras also sent its high school and elementary students home after the quake hit during the flag raising ceremonies. The class suspensions brought grid locks along most streets at the Central Business District even four hours after the jolt as most parents have to rush to fetch their children in schools, especially those in the elementary levels, as school administrators did not release pupils from the schools without their “fetchers.” Most were caught off-guard as some Baguio residents still remember the disastrous July 16, 1990 magnitude 7.9 “killer quake” that virtually sent Baguio and Northern Luzon on its knees. There were no reports yet of any damages as the National Grid Corporation (NGCP) immediately issued an advisory that power transmission service has remained normal after the jolt.
