Is the water cloudy? Warm cloudy water has been associated with earthquakes before, but always after the fact. Never heard of hot cloudy water appearing as a precursor to an earthquake.
I just checked the earthquake page and not much has been going on up there where you live, ito earthquakes, for the last week. But you might be onto something new that's never been observed before.
The water is crystal clear and sweet. It's just hot.
No earthquake or volcanic activity, although I've now had a couple people call and say that they are losing flow. That's how it started with mine.
