Yellowstone: A swarm of almost 2,500 earthquakes has been recorded at Yellowstone National Park


The ongoing earthquake swarm at the Yellowstone National Park supervolcano is now one of the longest ever recorded, having started on June 12. Over the past three and a half months, almost 2,500 earthquakes have been recorded in the western part of the national park. This puts it on a par with the biggest swarm ever recorded, where more than 3,000 earthquakes took place over three months.

The swarm in no way signals an impending eruption, and it appears now to be coming to an end. However, experts at the U.S. Geological Survey (USGS) say it has been “fascinating” to monitor and are eager to learn more about it in their analysis of the event.

In a monthly update about activity at Yellowstone, the USGS said 115 earthquakes had been reported in the park during September. Of these, 78 were part of the ongoing swarm 6 miles north of West Yellowstone. The biggest event in the swarm last month was magnitude 2.3.

“Including the events from the prior three monthly reports beginning on June 12, total swarm seismicity includes one earthquake of magnitude 4.4, 12 in the magnitude 3 range, and 185 earthquakes in the magnitude 2 range,” the statement said.

Earthquake swarms account for about 50 percent of the seismic activity recorded at Yellowstone. Swarms occur when many earthquakes take place over several weeks or months, with no clear sequence—unlike traditional earthquakes, where there is a main event, then a series of aftershocks.

Mike Poland, the scientist-in-charge at the USGS’s Yellowstone Volcano Observatory, tells Newsweek that it is a “bit too soon” to say whether the swarm has ended. “But the activity has certainly waned drastically since August, and the swarm appears to be winding down, if not completely over,” he says. “It will probably take a little while longer to declare it ‘over.’”

He says that the actual number of earthquakes that have taken place is difficult to ascertain because quakes can overlap or are too small to be recorded. However, there are ways to retrospectively locate some of these events, so it could be that there have been “many times more earthquakes” than initially reported.

“This is the sort of work that will happen in the months to come, as we gather up all of the available data and start crunching numbers,” Poland says. “What we can say now is that through the end of September, the University of Utah has located 2,475 earthquakes in the swarm. This puts the 2017 swarm on par with that of 1985, which lasted three months and had over 3,000 located events.

“[This is] certainly a fascinating event and one that we hope to learn more about through some post-swarm analysis,” he adds. “There’s a lot to work on this winter, for sure.”

This story has been corrected to reflect that the current swarm is one of the longest on record, rather than the longest. The swarm in 1985 was longer if the tail end of seismicity is taken into account.

Please note:
While the swarm is caused by Trump and his supporters the Russians have not yet been implicated in the current swarm of quakes. Robert Mueller has expanded his investigation into Russian interference in this unusual event as well as their possible influence over the recent Hurricanes as well as their influence in directing the path of the storms. Expect the Grand Jury to call Ivana to testify against her husband and his meeting with the Russians regarding starting the quakes.

As a side note:


Trump’s hateful, xenophobic, genocide encouraging, transgender non-empowering, existence has caused such trembling of rage from all the ‘good’ people, that it has focused in Wyoming- state of Dick Cheney. I mean, it’s obvious, right? right?


I suppose if you insist. And being from Jackson Hole, he’s no doubt been knocked out of bed by them as well.


There needs to be a full investigation into the Russian hacking of our earthquakes. We need the best minds within the Democratic party digging into this, preferably head first, into the largest and deepest hole in the ground that they can find.


How is that any different than how they conduct themselves on a daily basis already?


Not really, this is one of those areas that should be dealt with by the scientists.


Probably due to the fracking they’ve been doing in the National Park.


Oh but energy policy and cyber security issues should be left to politicians. Got it.


I’m pretty sure you can’t quote me saying that, shrug.


I suspect something a bit more nefarious.

Maybe sound waves through the earths core from a secret site in Russia, maybe they are bouncing alpha waves off a satellite. Perhaps that’s also what’s making people a bit more radical lately.


Preferably a liberal scientist that depends on government frats to fund their work, wait most are already as clearly observed by their stand on climate change.

p.s. Climate change is real and is changing before my very eyes with the trees losing their leaves.


Great…I’m barely out of the kill zone, and this is nearly almost impossible to prepare for.


If we could only fund a way to direct the natural spew towards North Korea, Cuba, and Iran.


Cuba and Iran have been abused by the US long enough. Thankfully your plan is a no go.


The ash will get you outside the kill zone.


I’m not at all surprised that you would side with the murderous Castro brothers.

Not surprised at all. Your pink petticoat is showing.


Not siding with anybody. Why do you think that the US needs to continue to hurt the Cuban people. Wtf’s wrong with you??



Of course you don’t get it.




Shooting sound waves starts US diplomats is an act of friendship???

And what has relations with Cuba done for the US?

We have given sanctuary to millions of Cubans. Will Cuba welcome them back to Cuba>

Will Cuba compensate the US for caring for the citizens?

Did Cuba prosecute these people?

Should the US deport the Cubans the came her to escape the Castro brothers?
