important applications of infrasound is to provide early warning of an ongoing large eruption so that aircraft can deviate from their paths and avoid the ash that comes with it.

That is like a very tangible application and that is basically now

in our toolkit for protecting lives and property, right?

And so that's one of them.

Another application that came very much to the fore with the Tonga eruption in 2022 is if you have a big eruption in the middle of the ocean, it will generate a tsunami.

And so the sound from the eruption precedes the tsunami by a substantial amount.

And that's also early warning.

If it's big enough, you'll go around the world multiple times.

Wow.

So yeah, there's that.

So at the turn of the century, we deployed the international monitoring system

to monitor clandestine nuclear tests, which has an infrasound network of arrays and deployed throughout the whole planet.

And so we have global coverage of infrasound at very high quality.

These are exquisite sensors that can pick up like almost anything.

Funny story.

Yeah.

When I arrived in Hawaii before the turn of the century, I was already an infrasound specialist.

I was doing infrasound before it was cool, right?

So I was like, oh, there's a volcano here.

This is awesome.
