Guess I don't have to worry about cutting back my ornamental grasses today.

now would be a good time to panic. Seriously, though, they had a much bigger quake there in the 50s and it didn't blow. This is the biggest I can recall in a number of years though.

not so much.

Hopefully just relieving stress!!

the star is in WY

NW Wyoming

or

37km ENE of West Yellowstone, Montana

A report from scientists at the University of Utah shows that the “supervolcano” underneath Yellowstone has risen at a record rate since mid 2004. Apparently, a “pancake-shaped blob” of molten rock he size of Los Angeles was pressed in to the slumbering volcano, some six miles down.

“There is no evidence of an imminent volcanic eruption or hydrothermal explosion. That’s the bottom line,” says seismologist Robert B. Smith, lead author of the study and professor of geophysics at the University of Utah. “A lot of calderas [giant volcanic craters] worldwide go up and down over decades without erupting.”

The journal Science however reported that the caldera floor of the massive volcano has risen 3 inches, per year, for the past three years. This is a rate of growth three times more rapid than ever observed, since records were first kept back in 1923.

“Our best evidence is that the crustal magma chamber is filling with molten rock,” Smith says. “But we have no idea how long this process goes on before there either is an eruption or the inflow of molten rock stops and the caldera deflates again,” he adds

Run Away!!!!!!!!!!!!

I'm not qualified to read this data, but the ground elevation monitors seem concerning:



Seem to be large and rapid shifts in ground elevation. You notice the red at the end of the graph on the bottom - there is rapid uplift in the park over the last few months.

of magma filling up the caldera of the supervolcano, but given the circumstances that is the most likely reason.

- edit -

Someone on another board says the rapid uplift is centered around NNW of Norris Basin and that the rest of the park is showing a slow subsidence. Here's what they said:

"The GPS is showing the ground movement at the surface over time. Over the past year, it shows uplift of approx. 50 millimeters (2 inches), as well as a small push of the Norris station to the SE. Looking at the stations surrounding NRWY (GPS monument), it looks like the uplift is centered to the NNW of Norris Basin. Elsewhere in the park, the land is still subsiding."

- end quote -

The earthquake was near Norris. This is starting to get a bit concerning, though no reason to panic yet (or ever for that matter, panic does nothing positive). And as I said, I have no qualifications to read gps data, the bottom chart ending in red doesn't look good to a layman, though.

the bottom line is increased uplift is usually associated with elevated seismic activity.

Which is why it is expected that after this earthquake seismic activity will remain elevated.

Look at the bright side, if (and when) it finally blows, mother nature would have found a temporary solution to global warming by throwing enough dust into the air to drop the average temperatures by 5 to 10 degrees for a couple of years.

TYY

a whole lot of people wont be there to see them........

It would be a shame for it to be destroyed.

Most of the US would be uninhabitable for decades and the rest of the world would be thrown into a nuclear winter.

Today's event is the largest earthquake at Yellowstone since February 22, 1980, and occurred near the center of a region of recent ground uplift described in a YVO Information Statement on February 18, 2014. The Yellowstone Volcano Observatory has been tracking this uplift episode for about 7 months.

As discussed in the March 3, 2014 YVO Monthly Update, seismicity in the general region of the uplift has been elevated for several months. A previous period of uplift in this area occurred between 1996 and 2003, and it was also accompanied by elevated seismicity.

A USGS field team is in Yellowstone and will visit the area near the earthquake's epicenter today. The team will look for any surface changes that the earthquake may have caused, and for possible effects to the hydrothermal system at Norris Geyser Basin.

So the uplift data I posted was accurate. The USGS seems to think the uplift is the reason for the earthquake.

the Good Friday quake of 1964.

My daughter in So Cal was actually watching a TV news video of my sister-in-law recounting her experiences in the '64 quake when that 5.1 shaker hit down there a couple of days ago. Kind of an eerie coincidence.

we're going to ALL be in trouble.

Might be interesting to look into it.

in this region is in Wyoming (Pinedale, Gas Hills, Sheridan, Kemmerer) and Montana (Billings area and east/south) several miles from the park boundary and off the main plateau. I don't know of any fracking in eastern Idaho unless it's over near Soda Springs area. I think the closest would be in and around Wind River IR... it's all over the place in west-central Wyoming... well, except for the parks area, it's all over Wyoming.

volcanic ash in Nebraska came from.

i posted about it a couple hours before you, because it woke me up, 40 some miles from my house.


And another at 3.3m a little after noon.

Some info, Fracking is going full scream ahead east, south and northeast of the park, not really close to the border but probably close enough to the magma pool. These quakes are on the west side of the park east of Norris geyser basin and Gibbon and Elk Meadows.
