According to a new study, a pair of recent earthquakes in 2018 and 2019 were not indicative of tectonic activity, but were seismic rumblings produced by the Black Rock Desert volcanic field – an ancient volcanic system in Utah's Sevier Desert that's been active for over 6 million years and, apparently, is still alive and kicking.
The two earthquake sequences in question occurred in September 2018 and April 2019, and were recorded by seismometers within the Utah Regional Seismic Network, as well as by instruments forming part of an experimental project called Utah FORGE, run by the US Department of Energy.
Subsequent analysis of the wave-forms from the episodes showed that these quakes weren't the result of tectonic activity, with shallow signals emanating from depths less than 2.5 kilometres (1.5 miles) under the surface.
The evidence suggests that, unlike other earthquakes in the area that stem from fault movements and tend to produce more seismic energy, the shallow 2018 and 2019 events were produced by the transport of volcanic fluids within the Black Rock volcanic field, whether heated water or rocky magma.
Despite the ancient age of the volcanic complex, its quietness in terms of obvious volcanic activity means it's a relatively little-known feature of Utah's large landscape. Black Rock's last eruptive event was over 1,000 years ago, resulting in the region's Ice Springs lava flows.
As for whether the most recent rumblings are indicative of future outbursts, there's no evidence for that, the researchers say. But these quakes are a reminder that Black Rock is still active after all these years, and that this dormant volcano is not extinct.

“that’s been active for over 6 million years and, apparently, is still alive” How do they know that?
Are they sure it’s not Burning Man?
What is that show with the big worms?
Maybe Burning Man will go the way of Pompeii, some day.
Giant Volcano at this point would almost be a garnishment to the past year.
Evidence of Global Warming no doubt.
“Tremors”, I think?
Correct
IMHO one of the best inherently American science fiction movies ever made.
Oh, yeah 😄
So what do you think has more to do with Artic ice thickness. A. The relative activity of underwater volcanoes and vents that release heat and gases or B. Cow farts. Hint: There is only one politically correct answer.
Black Rock Desert is in N Nevada....
WHERE is this area they are talking about????
You sure he doesn’t mean “Dune”?
I’ve been to Black Rock.
Defiantly evidence there of active volcanic activity.
Black Rock. That’s racist!
Yep...
Also, Spencer T. had a very "Bad" day there...
I used to hang glide over that desolation all the time. Craters everywhere, and long black tendrils of lava flows. You need to be two miles up to get across, or you will have to hunt for thermals. And a giant mud lake, must not forget that. Got the truck stuck overnight in that once whilst retrieving a fellow pilot that forgot to throw a penny in Pahvant Butte as he went over and the gods were displeased.
