Update 05:58 UTC: Although probably harmless (like PHIVOLCS is stating) many people were seriously scared because of the long different patterns of shaking

Update 05:46 UTC: Based on the present earthquake parameters (Magnitude, Depth, Population, etc) and our experience with earthquake damage impact, does not expect any serious damage from this earthquake because of the depth of the hypocenter (breaking point inside the earth)
