Possibly the most helpful and useful would be listing the actual city closest to the earthquake, then listing the bigger towns most people are familiar with. Although there's some gray areas, like your "East Pasadena" example. Once people hear the word "Pasadena," it narrows the whole area down pretty quickly.

When Caltech or the USGS posts an earthquake location, there is a descriptive location as well as a latitude & longitude. I am trying to make a case the gazetteer (town list) contains too many census designated places (unincorporated areas) & very small towns that most people have not heard of. Sometimes well known towns are omitted in deference to obscure neighbors (for example, East Pasadena is listed, but Pasadena is not).What do you think? Are you scratching your heads over some of the places that come up, or would you rather see them?Thanks!Kate
