What a 9.0 Magnitude earthquake sounds like

Wonder what submarine dudes who listen for enemy subs were thinking

Considering that the initial sound was almost 30 minutes long, I'm sure they knew something really serious was happening.

Sounds like someone just lost at Astroids

LOL, yeah. It sounds kinda video gamish if you listen to it on some bass-less speakers.

Try it with some headphones. There's a whole bunch of deep and creepy low end. Very ominous sounding.

OK. So slow it down 30 times and repost. I guess we wouldn't be able to hear it. So did it really make any noise?

Well, the audio is sped up 16 times. If you slow it down, it probably will be too low to hear. That doesn't mean it didn't make noise.

1:25 (or so) of sound that's been sped up 16 times. What was the original length of sound that you're hearing here, class?

[blackcatgrowl]

Welp, playing around with this using Audacity, I slowed it down from x16 speed to x4 speed. It's audible still, but not by much. Then I slowed it all the way down. There is maybe some increase in a really low rumble... but it's really hard to tell apart from background noise.

But keep in mind, that this sound crossed the pacific and then echoed around! And good lord... it goes on and on... never thought it took so long for two tectonic plates to slide around violently.

As a former submarine sonarman....

It would have been a continuous, very low rumble - elevated background noise. Since it would have been random, it definitely would not have been classified as anything. There isn't any narrowband to analyze, and of course the spread of the bearing of the sound would have immediately been known to have been fairly wide.

Back in the day we heard stuff like this (but not has long) often and classified it as geologics (as opposed to fish noises which were biologics).
