Posted by has in , , , , on Sunday, May 22, 2011

Residents in some areas of the Philippines rather had a shaky morning as two 5+ magnitude quakes jolted different provinces in the country.

As previously reported here on Noypistuff, Occidental Mindoro was hit by a 5.7-magnitude temblor at 12:42 am today, May 23. Just over 2 hours after, another quake struck General Santos City, Mindanao which registered at magnitude 5.3 on the Richter scale.

According to the Philippine Institute of Volcanology and Seismology (Phivolcs), the epicenter of the newest quake was recorded off 75 kilometers (km) Southeast of General Santos City. The tectonic quake has a depth of 139 km.

There have been no immediate reports of damage from the earthquake. The Institute also does not expect tsunami nor aftershocks from the General Santos quake.
