Magnitude 4.5 aftershock recorded at 1:40 a.m.

MANILA (2nd UPDATE) - A magnitude 5.7 earthquake struck Looc, Occidental Mindoro early Monday, rattling parts of Metro Manila and Calabarzon, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.

The tremor caused 112 aftershocks as of 5 a.m., with the strongest measured at magnitude 4.5, according to Phivolcs chief Renato Solidum.

The aftershock was recorded at 1:40 a.m., with Intensity 1 reported in Abra de Ilog, Occidental Mindoro. It had a depth of 65 kilometers.

"Dahil ito ay malalim, itong mga aftershock 'di nagdulot ng pagkaramdam, isa lang na mahina at di naman ito mapanira," he told ABS-CBN's Teleradyo.

(Because the earthquake struck deep, the aftershocks were not felt, only a weak one and it was not damaging.)

Some social media users from different areas in the capital region and Calabarzon reportedly felt the quake lingering for a few minutes.
