We don’t have very many earthquakes in Kansas… but I remember the first/only one I felt.

I was sound asleep when my Siamese woke me up by pawing my face… he then went and sat on the edge of the bed and growled aggressively (very out of character)… Not 30s later, things started shaking.

No idea how he knew, but it was pretty wild. He passed away in 2020, still miss him.

Cats and dogs have been known to feel/sense earthquakes before we can!

In the recent NYC ones there are videos of dogs howling before any of the tremors are noticeable by people. This is a common phenomena I believe.

Yes, it is common. See my sibling comment explaining it.

Homer Simpson: “Somehow the animals are always the first to know”.

Yeah 100%. I live in NYC, and before the quake, our golden retriever started crying and whimpering. A few moments later we felt the quake!

Dang, sorry for your loss. That’s a dope memory of the cat tho. As someone that happened find themselves in Taipei a couple weeks ago for the 7.4, my only thought was getting back to my dog, whom I promised I would get back to. She was sorta freaking out before I left; either could sense me leaving, or sense the earthquake I was heading to…

I know how he knew.

There are two types of sound in rock. P and S waves. P waves are pressure waves and go faster. S waves go side to side and are a bit slower. So you cat was woken by a hiss from the P waves, which arrive a bit before the earthquake that you can feel.

See https://manoa.hawaii.edu/exploringourfluidearth/physical/oce... to verify that there are two types of waves, and the P waves arrive first.

I have been living in Japan for a while, and in my experience you can feel the earthquake coming a few seconds before the big shaking start. I don't know how to describe it, it is not a sound, more like a very slight movement.

This seems like a good sensor to build for early detection. Is that what the sensors do?

Yes https://en.wikipedia.org/wiki/Earthquake_Early_Warning_(Japa...
