Smoke Rings from Etna.

Smoking is bad for you.

The atmosphere must be very stable there and with no wind. Etna quite often seems to produce smoke rings. I wonder if it's anything to do with the climate or if it's something to do with the internal shape of the volcano?

No one injured after [hydrothermal] explosion at Yellowstone​

YELLOWSTONE NATIONAL PARK, Wyo — A hydrothermal explosion Tuesday morning in Yellowstone National Park sent boiling water, steam and rocks high into the sky which then rained down on tourists that were along the Biscuit Basin Trail.
The explosion was caught on video by Vlada March as she and her family were on the boardwalk near the Black Diamond Pool.
March said her mother was hit by debris, but unharmed. The National Park Service said no injuries were reported.
The explosion damaged the Biscuit Basin boardwalk forcing park rangers to close it and the Biscuit Basin parking lot. Rangers said they did not know when the boardwalk may reopen.

This is not very unusual and is to be expected in a natural, volcanic area. https://www.usgs.gov/observatories/yvo/news/hydrothermal-explosions-yellowstone-national-park

And the idiots walk back closer to have a look. What if it went up again or didn't they consider that?

Had to look that one up.

Had to look that one up.

From the USGS website:
Hydrothermal explosions are violent and dramatic events resulting in the rapid ejection of boiling water, steam, mud, and rock fragments. The explosions can reach heights of 2 km (1.2 miles) and leave craters that are from a few meters (tens of feet) up to more than 2 km (1.2 mi) in diameter. Ejected material, mostly breccia (angular rocks cemented by clay), can be found far as 3 to 4 km (1.8 to 2.5 mi) from the largest craters.

Sounds fairly par for that golf course.

Yeah those tourists seem to be pretty happy go lucky about the very obvious danger. Kind of like those trump people the other day. Hardy breed, or somethin’ else? Hm.
