MANILA, Philippines — A magnitude 6.3 quake shook a large swath of Mindanao Wednesday night,  damaging a small college building in one city and prompting residents to dash out of homes and shopping malls in panic, officials said.

The shallow quake that centered 23 kilometers southwest of Makilala town in North Cotabato caused power lines to trip, cutting electricity in South Cotabato province. In General Santos, a fire hit Gaisano Mall moments after the tremor,  sending panicked shoppers to run for safety.


In Digos City, television sets fall down and the wall of the Cor Jesu College building, outside of which motorcycles were parked, crashed.


Leslie Francisco, a local disaster-response officer, said a small school building in the downtown area of Digos City sustained extensive damage but there was no report of anybody being trapped inside.

In Davao City, the inland quake sent people rushing out of malls.

Local officials have called off classes in  the cities of Davao, Cotabato and Cotabato province to allow engineers to check the integrity of building structures.

The Philippine Institute of Volcanology and Seismology (Phivolcs) recorded the quake at 7:37 p.m. at a shallow depth of two kilometers. Shallow quakes tend to cause more damage than deeper ones.

The US Geological Survey placed the magnitude of the quake at 6.4.
