An undersea earthquake shook the southern Philippines shortly before midnight Tuesday, close to an area struck by a stronger tremor last week, the government's earthquake monitoring agency said. No damage or injuries were reported.

The magnitude 5.3 quake struck at 11:56 p.m. Tuesday and was centered about 57 kilometers (36 miles) under the sea, 103 kilometers (64 miles) east of Prosperidad town, which is about 900 kilometers (560 miles) southeast of Manila, the Philippine Institute of Volcanology and Seismology said. Seismologist Romy Tabanlar said the earthquake was caused by the movement of the Philippine Trench, a major fault line that runs along the east of the country. (AP)
