Hoodoo Hodunit?! (Yellowstone Monthly Update – April 2025)
Well look at this mess! What’s going on? We’re just south of Mammoth Hot Springs at a place informally known as the Hoodoos. The official designation for the area is Silver Gate, named by an early Yellowstone National Park visitor because of the way the road wound between the closely spaced white and gray boulders. Looking closely, you’ll see the boulders are travertine. They are from ancient, now...

Morning Glory Pool Was Blue? (Yellowstone Monthly Update - July 2024)
The beautiful Morning Glory pool is located near Old Faithful. However, it has changed over time because of people and past climate. But how?
Swimming Pools at Yellowstone? (Yellowstone Monthly Update - June 2024)
Up until the 1950s, visitors to the Old Faithful area could take a dip. Not at a geyser, but in a real swimming pool. The full story is in this month’s video update. During the month of May 2024, the University of Utah Seismograph Stations, which monitors and operates the Yellowstone seismic network, located 62 earthquakes. Deformation trends observed since 2015 continue. There was one water...
Mount St. Helens VS Yellowstone (Yellowstone Monthly Update - May 2024)

TUFF TIME: Mystery of disappearing deposits (Yellowstone Volcano Update - October 2023)
Yellowstone is a geologic wonderland with over 2 billion years of Earth's history recorded in the rocks. But some of that history is missing. Where did it go? We’ll look into that mystery in the October 2023 update from the Yellowstone Volcano Observatory.

Yellowstone Volcano Update — July 2023 — NEW THERMAL FEATURES at Yellowstone!
Geysers and hot springs are some of the most dynamic geologic features on the planet. They are always changing and sometimes that change happens in places where we can see and appreciate it. This has been the case on Geyser Hill, near Old Faithful, in Yellowstone National Park. The activity started May 24, 2023. Aurum Geyser began erupting for the first time in two years, and Beehive Geyser began...
Yellowstone Volcano Update — June 2023

Monthly update of activity at Yellowstone Volcano, April 1, 2023
Do animals prank humans? It sometimes feels that way, says Yellowstone Volcano Observatory’s scientist-in-charge Mike Poland. Mike shows some of the ways animals have “interacted” with monitoring equipment in this April 1, 2023 monthly update of activity at Yellowstone Volcano. Herds of elk or bison make a lot of noise when they walk by a monitoring station. The noise is picked up by the...
Monthly update of activity at Yellowstone Volcano, March 1, 2023
Could an external event trigger a Yellowstone eruption? No, says Yellowstone Volcano Observatory’s scientist-in-charge Mike Poland, that’s not how volcanoes work. Most of the pressure that drives a volcano toward eruption comes from within, from the exsolution of gases in the magmatic system. External events, like large earthquakes or nuclear blasts, can't cause that. This question arose in 2019...
Monthly update of activity at Yellowstone Volcano for Feb 1, 2023
Winter has arrived in the Yellowstone region. The deep snow and cold temperatures are harsh for animals, harsh for humans, and also harsh for volcano monitoring equipment. To protect the instruments and keep data flowing, seismometers are buried, and solar panels and radio antennas are positioned high enough above ground to prevent them from getting covered in snow. But the pole-like GPS antennas...
Monthly update of activity at Yellowstone Volcano for Jan 1, 2023
Mike Poland, scientist-in-charge of the Yellowstone Volcano Observatory, provides an overview of 2022 events and December activity in this monthly update for January 1, 2023. 2022 was an average year for earthquake activity.

Monthly update of activity at Yellowstone Volcano for Jan 2022
This monthly update from the Yellowstone Volcano Observatory begins with a story. Many would enjoy the adventure of a bicycle expedition to Yellowstone National Park.

Recap of Yellowstone's 2021 activity and December's monthly update
Before we get into what happened during the month of December 2021, let’s review what happened at Yellowstone over the past year. 2021 Seismicity Typically, there are 1,500 to 2,500 earthquakes located every year in the Yellowstone region. In 2021, there were 2,773 located earthquakes scattered throughout the Park. Consistent with previous years, most earthquakes were caused by water circulating...

Yellowstone's ups and downs explained in this monthly update of activity at Yellowstone Volcano (December 1, 2021)
Some people have characterized the seasonal rise and fall of Yellowstone as being like breathing. During the summer there is a little pause in the overall trend of subsidence and sometimes even a short episode of slight uplift. The trend reverses in early winter. These summertime episodes are caused by groundwater recharge. As the snowmelt percolates into the subsurface, the ground expands like a...
November (2021) Yellowstone Volcano
The November 2021 YVO Yellowstone Volcano update comes to you from a very snowy Norris Geyser Basin with a story about Porkchop Geyser’s 1989 explosion. Porkchop Geyser was named in the 1960s because it had a shape that looked a lot like a pork chop. In the 1970s to 1980s, it started having intermittent geyser eruptions, becoming more and more active. On September 5, 1989, Porkchop Geyser exploded...

Monthly update of activity at Yellowstone Volcano for July 2021
During July, Yellowstone caught everyone’s attention with 1,000+ earthquakes located in seven distinct earthquake swarms. The largest swarm occurred beneath Yellowstone Lake and had 764 earthquakes, the largest of which was a Magnitude 3.6. While this seems like a lot of earthquakes, it is not the most Yellowstone has experienced in any given month and the volcano alert level remains unchanged...
Monthly update of activity at Yellowstone Volcano for June 2021
From the boardwalk near Echinus Geyser (the largest acid geyser in the world), Yellowstone Volcano Observatory Scientist-in-Charge Mike Poland provides an update on activity in Yellowstone during the month of June.

YVO monthly activity update from rim of Yellowstone's Grand Canyon!
Yellowstone Volcano Observatory scientist-in-charge Mike Poland provides the YVO monthly update from the rim of Yellowstone’s Grand Canyon. The V-shaped gorge tells an amazing geologic story. About half a million years ago, a large rhyolite lava flow erupted. Over time, hot water and gases heated by the magma chamber rose through faults in the lava flow. And as it rose, it began altering the rock...
YVO Update of Activity at Yellowstone and Plans for Summer Fieldwork
It's May, the snow is melting and the roads are mostly open, so it's time for geologists, geophysicist and geochemists to head into Yellowstone to start projects they have been planning for the last several months. Next week, a field team will deploy a temporary GPS network to help “densify” the network of continuous GPS stations already in place. The temporary GPS stations are low profile, low...
YVO Update: Activity at Yellowstone and Volcanoes of Desert Southwest
There are thousands of volcanic features distributed throughout the southwest United States, which are grouped together in volcanic fields. The Yellowstone Volcano Observatory monitors these volcanoes using a combination of techniques. While YVO hasn’t seen anything to suggest magma is on the move, the area is stretched and pulled apart to produce numerous tectonic earthquakes. YVO keeps an eye on...
"Not all eruptions are Armageddon" - Yellowstone Update for March 2021
Mike Poland, Scientist-in-Charge of the Yellowstone Volcano Observatory, debunks the misconception that if Yellowstone were to erupt, it would be Armageddon. In fact, the most common form of eruptive activity at Yellowstone is a lava flow, and even those aren't that common. They happen only once every few tens of thousands of years. Learn more in this monthly overview of activity at Yellowstone...
