MANILA, Oct. 16 (Xinhua) -- Another earthquake of 5.5 magnitude struck Sultan Kudarat province in the southern Philippines on Wednesday, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.

It was the second earthquake that shook Mindanao island.

The second earthquake, which struck at 8:09 p.m. local time, hit at a depth of 5 km, 16 km southeast of Columbio town in Kudarat province.

The institute said the first inland quake, which struck at 7:37 p.m. local time, hit at a depth of 15 km, about 22 km southeast of Tulunan town.

No injuries or damage have been reported. But the institute said they are checking if the first quake that rattled North Cotabato caused any damage or injuries.

The first quake with a magnitude of 6.3, which was tectonic in origin, was also felt in Kidapawan City, Tupi in South Cotabato province, Alabel in Sarangani province, T'boli also in South Cotabato, General Santos City, Cagayan de Oro City, Gingoog City, Misamis Orietantal province, Dipolog City and Bislig City.

The first tremor is expected to cause damage and aftershocks, the institute said. However, it said the second quake will not cause any damage or generate aftershocks.
