Looks like the Ring of Fire thread was closed for lack of activity. Wish we could say lack of activity around Yellowstone. Looks like the north american super volcano might be telling us something. I know these quake are in Montana but that's just east of the existing historic eruptions. Magma hot spots move. Look at the Hawaiian chain.
I was planning on taking my kids to Jackson Wyoming to watch the total eclipse in August. Think I will go to Oregon instead.

Methinks these super volcanoes are probably not cataclysmic but very odious for a long time period. If you're driving Oregon is closer for you but AFAIK all lodging is gone and that includes campsites.

Thera is such a volcano, there is a mural/fresco there in an old unearthed building that matches the Atlantis myth to a T, they even had internal plumbing and toilets, sad, when Thera went off, it caused a Tsunami that wiped out populations on Crete and other islands nearby.

Magma hot spots move. Look at the Hawaiian chain.

In the case of Hawaii, if I recall my geology correctly, the hot spot stayed in the same place but a plate of the Earth slowly moved over it, creating the chain of volcanic islands.

Campi Flegrei near Naples is a dangerous super volcano, whose magma chamber is connected to that of Vesuvio.

Correct, here the hot spot for the local activity vanished, so what is left behind, is a bunch of extinct volcanic formations and cones.

I don't think that Yellowstone would be considered 'extinct'. Just laying in wait for the 'big one'.

I was not referring to Yellowstone Mark, where I live, has quite a bit of extinct formations and cones.

Ahh....I thought you were referring to the continental US in general, VS Hawaii.

The United States Geological Survey said on its website that the preliminary magnitude 8 quake hit about 73 miles off Tres Picos, Mexico.. "Widespread tsunami waves are possible," the Pacific Tsunami Warning Center said.

Nobody honestly knows when Yellowstone will go bang, but most do agree that it is overdue geologically speaking. It's the same with the San Andreas fault, that is apparently overdue to go again we are told. The same with the next eruption on Mount Etna.

But it doesn't seem to stop people living on top of these things does it? It doesn't seem to stop people living in "Hurricane Alley" in Southern USA, that get battered every year.

Hurricane irma continues to cause devastation, no doubt the end of the world soothsayers are having a field day.

Peoples choice to juggle the odds I guess.

Oh, no. Harvey and Irma are direct effects of 'climate change'.

What's the betting that the Cascadia Subduction Zone is the next massive one. All along the coast from Northern California to Canada.

The Cascadia subduction zone is a convergent plate boundary that stretches from northern Vancouver Island to northern California. It is a very long, sloping subduction zone that separates the Explorer, Juan de Fuca, and Gorda plates, on the one hand, and the North American Plate, on the other. The denser oceanic plate is subducting beneath the less dense continental plate offshore of British Columbia, Washington, Oregon, and northern California. The North American Plate is moving in a southwest direction, overriding the oceanic plate. The Cascadia subduction zone is where the two plates meet.

I think I just about followed that .....

2010, studies suggested that the risk could be as high as 37% for earthquakes of magnitude 8.0 or higher.

Geologists and civil engineers have broadly determined that the Pacific Northwest region is not well prepared for such a colossal earthquake. The resulting tsunami might reach heights of approximately 30 meters (100 ft). FEMA estimates some 13,000 fatalities from such an event, with another 27,000 injured. It predicts that a million people will be displaced, with yet another 2.5 million requiring food and water. Other analyses predict that even a magnitude 6.7 earthquake in Seattle would result in 7,700 dead and injured, $33 billion in damages, 39,000 buildings largely or totally destroyed, and 130 simultaneous fires.


It just seems to me that there are certain areas of the world, particularly on the pacific rim of fire, and others, that it just doesn't make sense to live in. The cataclysm could happen next week or 200 years time. Yes they have modern monitoring devices. But ask yourself this

Q Did anyone predict Hurricane irma 3 months ago?
Q Did anyone predict Hurricane Harvey 3 months ago?

Despite having sent man to the moon, and robots to Mars, and having super computers, we still have less ideas about our own planet than others in the solar system . Of course we cannot control plate tectonics and subduction zones, or weather patterns, but we don't HAVE to be stupid enough to live on top of them.

There were warnings a few months ago that this was likely to be one of the worst hurricane seasons on record, but of course that was drowned in other news as "weather men over reacting".
As to predicting earthquakes and volcanic activity - we are still very much having to rely on the recent geological record to get an indication of "timescales of worry" - one needs very accurate measurements from locations that are very difficult to access to be able to predict with some degree of certainty that an event is due in a given (longer) timescale.. Taking one fairly recent event, Mount St.Helen's eruption. Without the monitoring that was taking place it is quite possible that there wasn't the knowledge that an eruption was possible, even then, it wasn't until the last few days that people understood that it was imminent, even then they couldn't say the exact day, let alone time of that day.
As to living within the danger zone - many volcanoes and earthquake zones are actually some of the most productive places in terms of farming. So people live there because they can grow food very well, and live with the danger.

edit]re: Cascadia,
The event in 1700, before the illegal immigrants set up on that coast, was recorded in Japan. So other places are also at risk.

And how much of the world, or even this country, would be declared 'uninhabitable' if the undefinable risk of natural disaster were taken into account?
Like maybe the entire west coast. Or the entire state of Florida?
While certain things are risk enough that it might make sense, reality does not allow for everybody always living 'out of harm's way'.
