I was in that earthquake. Was finally able to check in to a hotel now. It was very scary. The room was shaking for at least 5 minutes and the walls were cracking. We all ran outside, down the stairs, and waited across the street until the engineers told us to walk far away. Then the siding started falling from the building (29 floors).
Hope you are staying safe Does Philippines have seismic building codes? Probably not right ?
It's a poor country with a lot of ramshackle housing and "informal settlements" (slums). Seismic codes exist, implementation and enforcement are an entirely different matter.
