It makes people stop asking "can we do anything about it".
Japan and San Francisco both finally started asking those questions about earthquakes. At first it seemed "impossible". And really, the first attempts were less than totally successful. But over time we've engineered better and better building methods such that it is VERY noticeable when an earth quake hits an area that has not incorporated these kinds of building codes.
