#radon #earthquake
In the past week, we've been detecting high amounts of radon from our detectors that we previously have not. It has not been a seasonal change as we have not opened nor closed windows more often. I wondered if someone was doing some kind of construction near by to release more into the air as it was coming from outside not inside.

And then, boom! Earthquake. I wondered if there was a link so I did a little Google search. Turns out, yes.
