I am sure you could still remember the earthquake in Bohol last year, it collapsed some buildings, and churches, and even houses. Recently an earthquake again strike in some parts in Manila, it is not as strong in Bohol but everyone is alarmed. And I am too because I know if a strong earthquake will strike in our place as strong as in Bohol, I am sure our house would give in. Anyway if you are worried too, you can answer some of the question of the picture above, try to check if what bracket your house is in and consult an expert what to do with your house.
