Why did so few people die in the recent 1989 san fransisco quake?
California now has a good building code. It is more expensive to make a house or a building so it will not fall down in an earthquake but it is possible. Concrete is not a strong material. Adding rebar to concrete makes it much stronger. In earthquake zones much more than the average amount of rebar must be added. The roof must be attached to the building rather than just placed on top. That makes the building a solid unit. Thus, unlike Haiti, the buildings in California are built to withstand an earthquake. If the building does not fall down on a person, the person will not be killed by a falling building! If the infrastructure is not harmed, it will not be followed by a cholera epidemic.
