OK, this is wild.

In September 2023, geophysicists across the world started monitoring a very odd signal coming from the ground under them.

It was picked up in the Arctic. And Antarctica. It was detected everywhere, every 90 seconds, as regular as a metronome, for *nine days*.

What the HELL?

Got a little snow overnight in NE Travis county. Last band of precipitation this morning is mostly graupel, just like it started last night. #atxwx
