Two earthquakes measuring 6.1 and 5.9 on the Richter scale respectively shook the Philippines on Thursday, with no immediate reports of casualties or infrastructure losses, according to the Philippine Institute of Volcanology and Seismology.
The 5.9 magnitude tremor took place in the Southern Leyte province on Thursday morning, at around 7.39 am (2339GMT) some 7 kilometers (4.3 miles) southeast of the local town of San Francisco, also in the same province, The Manila Times reported, quoting Teresito Bacolcol, the institute's head.
The earthquake took place at a depth of focus of 10 km (6.2 mi).
It was followed by a 6.1 magnitude earthquake in the Zamboanga del Norte province at 11.41 am (0341GMT).
The tremor happened around some 2 km (1.2 mi) southeast of the town of Siocon.
Although there were no immediate reports, both damage to infrastructure and aftershocks are expected from the quakes, Bacolcol said.
A quake measuring 5.2 magnitude on the Richter scale struck Japan's Fukushima Prefecture and adjoining areas early Thursday.
