Taupo Alert Raised to Level 1 (September 21, 2312 UTC)


September 21, 2022, 4:12 p.m., Pacific: There are no new official updates — GNS Science doesn’t routinely post daily updates like the USGS often does when volcanoes are restive.

I just wanted to point you toward this article by volcanologist/blogger Erik Klemetti.

He covers this far better than I could, of course, so there’s no need for me to do that special Taupo post this coming Sunday after all (the regular Sunday Morning Volcano feature is about a supervolcano, but it’s in California, not New Zealand).


Original post

Taupo, in New Zealand, is a supervolcano, but such volcanoes have “normal” eruptions, too.

It’s also a restless caldera, which means that it has earthquake swarms off and on. It’s having one now, and because of this, the volcanologists decided to raise the alert to the lowest stage, level 1.

No supereruption is pending — Taupo is heavily monitored and the precursors of such a thing likely would be HUGE — but maybe we’ll get to see a “normal” one, somewhere in the caldera?

If so, it will be Surtseyian (explosive) because of the crater lake.

This is not an emergency, and my schedule is tight this week, so I’m going to let the volcanologists speak

Literally, too:



— and plan to do an in-depth post this coming Sunday, unless something dramatic — and most probably nonsupersized — happens before then.
