A powerful
earthquake shook the southern Philippines on Tuesday, triggering landslides and loosening boulders that killed six people and injured more than 100 others in a region already damaged by a strong quake two weeks earlier, officials said.
The magnitude 6.6 earthquake was caused by the movement of a fault about 7 kilometers (4.3 miles) deep about 25 kilometers (16 miles) east of Tulunan in Cotabato province, the Philippine Institute of Seismology and Volcanology said.
Tulunan Mayor Reuel Limbungan said about 90% of the houses in three rural villages were damaged by the intense ground movement.
