#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.

@Ringtheory wow, that's awesome, now my radon detector is an earth quake detector! I'll have to set up some Home Assistant automations

@greg The questions I have now are how advance warning is it and of what magnitude correlation. Was the week ago spike a pre-detection of the one that was yesterday or detection of other quakes local in the area that I didn't feel? Or is it in detection of something larger in magnitude that is going to come? 🤔

Definitely need some data collection! 💜

@Ringtheory I assume AirThings has this dataset. It would be a fun dataset to play with.
#AirThings, are you on here? Would you consider releasing some anonymized data?

@greg AirThings has 2 sets of my data. 😅

@greg For reference, this is the shake map of the last 30 days in the area, so that spike from 30 days ago is also interesting to me.

@Ringtheory @greg I've been looking for radon correlations too. For awhile low pressure systems seemed to coincide with higher radon.

@NotMyBub @Ringtheory oh, I found something similar but I correlated it with rain (low pressure system proxy). I assumed the rain was increasing the soil pressure and forcing up radon. I'll look into the low pressure system correlation.

Low pressure is also known to increase radon levels in a house.

Does barometric pressure change radon levels?
