A quick search of the USGS catalogue shows that two earthquakes occurred at the same location, very close to the Port of Batangas. The events struck 1 minute 26 seconds apart. The first quake had a magnitude of 5.5; the second, stronger event had magnitude 5.9. According to the USGS, the first event caused a maximum shaking intensity of Level 5 (moderate shaking), whereas the second stronger quake resulted in shaking intensity of Level 7 (very strong). You can see this difference in shaking intensities in the video (for a description of the different levels of shaking, see this page). So far, there are no reports of significant casualties caused by these earthquakes.
Aside from the science of this earthquake, it is interesting to see the reaction of the people to the shaking in this video (apart from those who hid under the transit structure). First and foremost, the reporter maintains excellent composure. More importantly though, in my opinion, the people in the video respond well to the shaking. There isn't too much panic, people steadily move away from structures that could fall, and many people crouch down to ensure that they keep their feet steady and do not fall over. The reaction of people in this video highlights how people in the Philippines are accustomed to feeling strong earthquakes, which occur all too often in the country. In fact, the same area in the video was hit by a magnitude 5.1 earthquake four days earlier. Perhaps this event could be classed as the true foreshock ...
