Is anyone else starting to see a pattern here?

Do you know that Steamboat Geyser at Yellowstone has erupted 8 times so far this year? Just recently twice in one day. This geyser usually only erupts every few years. https://volcanoes.usgs.gov/volcanoes/yellowstone/

The govt is low key about it...and probably right. But the big picture says something is going on down there. I think it's related to the pole shift...Lots of turbulence in the molten core of the earth stirring things up...

baha - Interesting catch...thanks. Such variations in the Yellowstone magma chamber have been monitored for years. But volcanic activity is not related to activity in the earth's core. From

https://blogs.agu.org/martianchronicles ... -come-fro/

"Lava: Where does it come from?

Well, volcanoes. And the lava in volcanoes comes from deep in the earth where everything is molten, right? Wrong! It’s true that as you go deeper into the earth, things heat up, but the earth isn’t a crispy rock shell around a gooey molten center. The crust, mantle and inner core of the earth are all solid rock (or iron in the case of the core). The only large portion of the earth’s interior that is liquid is the outer core, and lava does not come from there (again, if it did, it would be molten iron)."

Volcanos, as well as hot spots that generate geysers, are very shallow and cover a very limited area compared to the entire globe. As such activity in Yellowstone, Hawaii, Guatemala, Iceland et al are not related.

I used to live on the slope of the next volcano over, Volcan de Agua. I was up above Ciudad Vieja above Antigua. It was about 5 miles from Volcan de Agua. There were earthquakes all the time and Volcan de Fuego would smoke as I recall.

It's been erupting a lot lately. The two volcanoes were the reason they moved the capital down to Guatemala City.

I hope Antigua is okay. It's right beneath both volcanoes!

well it depends on what you mean by "liquid". If you use it in the context of liquid as in a glass of water or liquid in the context of physical properties where for all intents and purposes a material behaves as a newtonian fluid. In the latter case the upper asthenosphere behaves in this manner, most of the rock material is in a molten form and behaves as a newtonian fluid. And what is "shallow" is also a matter of perspective. The upper asthenosphere where the Yellowstone hot spot originates is at a depth of around 30 km, which would be shallow in the context of the depth to the inner mantle but in itself is pretty deep. Yellowstone and Kiluea are both hotspot related whereas many of the others are related to rising partical melt back arc of subduction zones. To some extent back arc basin volcanoes located along the same plate margin can be related as they are partly due to speed of plate spread and hence subduction. In the distant past there does seem to be some relationship between the speed of plate accretion (measured by spacing of magnetic stripes on the sea floor) and periods of greater volcanic activity. Still not well understood.

Just in the last few days we have Sakurajima in Japan, Klyuchevskoy in Kamchatka, Ebico, Sinabong...should I continue?
https://www.volcanodiscovery.com/volcan ... Sinab.html

This site shows 8 'new' eruptions.
https://volcano.si.edu/reports_weekly.cfm

Steamboat has gone off again. Many long dormant volcanoes around the world are experiencing earthquake swarms beneath them. Including Mt Rainier and Mt Hood.

The USGS says not to worry. This happens all the time...so do eruptions!

Do I look worried? 8O

Not really a volcano, or even an earthquake...but...wow!!

Revi - Same problem we have here with folks building in active flood plains. Cheaper land just like the areas at the base of volcanic slopes. A good plan...until it isn't.
