Very Strong deep earthquake in Mindanao, Philippines

Last update: February 16, 2013 at 10:44 am by By

Update 06:15 UTC : The earthquake has been felt in a wide radius which is normal for deep earthquakes. The earthquake waves are propagating from deep in the earth to the upper layers.
Our Philippino readers are reporting relatively high shaking values for this earthquake.
As you can see on the lower map, this is the strongest earthquake in this area for more than a year. The map shows also that the area is seismically very active.

Update 06:10 UTC : Phivolcs published slightly different data than the other agencies : M6.2 at 100 km
Phivolvs did report the following shaking intensities :
Intensity IV – Mati & Taragona, Davao Oriental
Intensity III – Davao City
Intensity II – General Santos City, Butuan City, Malaybalay, Bukidnon
Based on their theoretical models, Phivolcs does not expect any damage out of this earthquake. They expect (as usual) a number of aftershocks.

Update 05:43 UTC : The shaking was theoretically expected to reach a max. V or moderate shaking

A very strong deep earthquake occurred approx. 30 km out of the Mindanao coast. The earthquake was not powerful enough to generate a tsunami.

    People :
    Felt by persons at rest, on upper floors or favorably placed.
    MMI III (Weak shaking) ?
    People :
    Felt indoors; hanging objects may swing, vibration similar to passing of light trucks, duration may be estimated, may not be recognized as an earthquake.
