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'.
Al Gore is having a field day......LOL.

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

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'.

OMG.....
Somebody else's mind has left the planet along with Al Gore's.
Poor Jennifer Lawrence thinks Hunger Games has become real life.
And to add a little Hollywood touch (she's 'touched' all right), she even adds in politics. (Bring up that hurricane in sector 3).
Hurricanes Irma, Harvey are nature's 'wrath' for Trump victory, Jennifer Lawrence claims.

There is always one stupd tart about ..... Oscars mean nothing, your agent can buy you one behind the scenes.

Just a bit more proof that most actors/actresses should stick to acting.

Was that acting the part or acting the fool?

Sadly, I don't think she was acting.
Maybe just shooting off her mouth to get a dig in on the president and didn't fully realize just how stupid it made her look.
