People have to remember that the local geology affects how an earthquake is felt in a particular area. A 4.5 may cause minor chalking in some areas, but the ground is other areas might result in enough vibration to knock a person, or an un-reinforced house, down.
Hubby was in Loma Prieta for the races when that quake hit. For all I knew, he was on the Nimitz Freeway! I was very worried. As it happens, he was by Coit Tower, great view of the shaking and geologically one of the sounder places there, being hard rock. His hotel was cracked a bit and tourists from the UK were understandably freaked, this being new to them and all.
