In a matter of seconds 92,000 people lost their lives. That year in England and Canada there was no summer. It snowed in June and frost was present throughout what was supposed to be the summer months. Global temperatures had plummeted. The following year, 1816, 200,000 people died of disease and starvation.

All of this due to a super volcanic explosion on the island of Sumbawa, Indonesia. The explosion had sent rocks & ash 28 miles high and 12 cubic miles of magma into the air. The first eruption was loud enough to be heard as thunder by people living over 800 miles away.

The VEI is an index of the force of volcanic activity (Volcanic Explosion Index)

Mount Saint Helens: VEI 5
Mount Tambora (on island of Sumbawa) VEI 7

Besides Yellowstone National Park ...are there other places in the U.S. a super volcanic eruption might occur ?

Long Valley Caldera, California**
La Garita Caldera, Colorado - 27 million yrs ago this one produced one of the largest super volcanic explosions on the planet & deposited 1,200 cubic miles of magma
Valles Caldera, New Mexico

**this one is so dangerous that the U.S. Government created an escape route and named it the "Mammoth Escape Route," though business owners complained that the road would scare away potential customers. The road was renamed the "Mammoth Scenic Loop," though its purpose is to serve as an emergency escape route if the volcano shows signs of imminent activity.

The ground at Yellowstone National Park over the caldera has been rising as much as 2.8" per year. The magma pool is 6 miles below the surface. The park is monitored continuously for earthquake swarms and elevation changes.

Frankly, the thought that this thing is being monitored by the U.S.Govt on a continuous basis does make me wonder if I'll ever make another another trip there

I hope you enjoyed the read

You really need to take a hike in the woods or along the coast. Take a break from your obsessions.

lol ! it's not a obsession .... it's interesting stuff !

Yes, it is interesting stuff. But you have an obsession with catastrophes and potential catastrophes.

Breathe, relax, take a walk.

It might seem that way i suppose but its nature at its worse and the science behind it that interests me ....i guess a little bit like a storm chaser. I grew up on the Gulf Coast and had to go through a strong Hurricane - ever since then i became interested in these massive storms . Maybe i should have become a weather guy but that's not the road i decided on for a career.

That was one long year!

If you want some feedback from another old-timer here:

I don't like clickbait articles. And the way you create these threads (Complete With All Caps Leading Title) makes the CH look like a clickbait facebook page.

Firstly ... As with what Alicatt said, that was a hellava long year .. but we all understand it was a typo

Secondly, I have seen docos as well re: super volcano's especially Yellowstone. I don't take that great a concern because well, if it's gonna happen then a lot of you guys won't survive and the rest of us are going to be affected in some way or another anyway!
Whether a good read or not Haggart wad expressing his views for perhaps those of which may be interested.

Myself personally do not give a rat's rectum ... when it happens, so be it, nothing you or I can do about it.

Thirdly ... Leave the poor guy alone ... He's probably already taken enough walks, breathing exercises etc.

Perhaps he may already be relaxed!

thanks - fixed the typo. I always include the link to the full article at the bottom RSColonel and there are articles or subject posts at SimHQ/ CH that i don't read either simply because it doesn't sound like something I'd be interested in. I'm sorry you don't like the caps in the title posts but we all have our preferences

Well, 1815 was indeed a very crappy year to be French!

hehe - yea was reading the timeline after your post - one can say for the French it was a rather "turbulent" year
