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.

Busting Myths About One of the Largest Volcanic Systems in the World - The Top 10 Misconceptions about Yellowstone Volcanism

By Michael Poland, USGS Scientist-in-charge, Yellowstone Volcano Observatory

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.

Yellowstone’s semi-permanent GPS sensors head home for the winter.

Yellowstone Volcano Observatory scientist-in-charge Mike Poland tells the story behind the color change of Morning Glory Pool and shows how to recognize seasonal changes in ground deformation data in this September 1, 2021 video update of volcano and earthquake activity at Yellowstone Volcano.

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.

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. The Yellowstone Seismic Network located 445 earthquakes in the Yellowstone National Park region.

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.

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.

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.

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.

Just what is the Yellowstone Volcano Observatory? In this video, Mike Poland, Scientist-in-Charge of YVO, gives an overview of the institutions that make up the Observatory, how YVO monitors volcano and earthquake activity at Yellowstone, the geologic hazards of the region, and some of the noteworthy new results and observations from YVO scientists.

Yellowstone Volcano Observatory Scientist-in-Charge Mike Poland visits Yellowstone National Park to tell the story of how the ground there moves up and down over time. This motion has been measured using a variety of techniques over the past 100 years, and from geological mapping scientists can even tell how the ground has moved going back about 15,000 years!

This time-lapse movie, which spans January 2019 to August 2020, shows the changing nature of the seasons at Yellowstone Lake as captured by the Yellowstone Volcano Observatory webcam. Snow and ice come and go, and there is even a wildfire visible during the summer of 2019!
