Listen to roughly the last hour of activity at these volcanoes:

Volcano - Seismic stations are announced in each ear.
Wrangell| Spurr| Redoubt| Iliamna| Augustine| Veniaminof| Pavlof| Shishaldin| Okmok| Gareloi

The "voice" announces the start time of the sequence. Now, of course, not all these stations may be functioning at the moment

However, you can listen to an example here.

Things that sound like gunshots and crashes are "Typical" Earthquakes.
Things that sound electronic... are -- example, calibration pulses.

Sounds are unfiltered, and sped up 100x so that an hour becomes 36 seconds
Amplitudes are normalized.
