In my college Animal Behavior class we talked about some cases, but that was quite a few years ago so I don’t remember details. All I really remember was it had to do with infrasound/ultrasound. I did a quick Google and found an article but don’t have time right now to read the whole thing. Here’s an excerpt though:

“The Boxing Day Tsunami on 26 December 2004 was created by a magnitude 9.0 earthquake, 160 km off the northwest coast of Sumatra, one minute before 0800 local time (00:58:53 UCT). The earthquake resulted in a 15.6 m (50 ft) wave that crashed onto the coast of Sumatra. This wave impacted the shoreline, producing low-frequency sounds at and below 100 Hz with much of the energy residing in infrasonic frequencies between 1 Hz and 10 Hz. These sounds travel in the atmosphere at the speed of sound. At the tropical ocean surface this speed will be about 1260 km/h. The tsunami, in contrast, travels at a speed of 700 km/h. Elephants at locations 1000 km distant from Sumatra (Phuket, Thailand and Yala National Park, Sri Lanka) detected and responded to this sound wave 38.1 min prior to the arrival of the tsunami. No elephant in either location was lost or injured. In contrast, a significant number of people on the beaches of Thailand lost their lives [17].”

Edit: And I do realize this may have had more to do with the tsunami as opposed to the earthquake, but if someone wants to read that article there may be more in there specifically regarding earthquakes.

I know, but thank you. It’s important for people to know. A few years ago I didn’t know dogs couldn’t have grapes either, so now i tell everyone. Anyway, I told my wife to move the sub away from the edge like 10 minutes before he grabbed it, so it was a funny “told you so” moment.

We don’t give him human food at all besides stuff we know is OK, so a few onion slices by accident shouldn’t be too bad from what I’ve read (it was just a couple bites left). I do know the toxic chemical can build up over time, though, so we try to be careful of stuff in the onion family.

Funny enough, this was my wife’s portion and she stepped away for a second and he snatched her leftovers. So he didn’t even wait for it, haha.
