John,

You seem to be knowledgeable about animal behavior which might not be quake related. If there were a series of 4.0 earthquakes in a city and rats were observed coming out in the daytime, wandering around aimlessly, seemingly lost and it went on for a time without any indication of underground source causing a problem, would you consider it might be a precursor to a large earthquake?

I guess I should be specific. Let's say the area in question was two square miles around UCLA.
