Caldera Chronicles

Two pretty good-sized earthquakes shook the western U.S. in March, a M5.7 in Utah and a M6.5 in Idaho. These quakes not only shook up the people...

Before YVO's founding, research had been conducted on the volcanism and tectonics of the Yellowstone region since the 1960s by the University of Utah...

First, there was the March 18, 2020, magnitude 5.7 (M5.7) earthquake near Salt Lake City. And then there was the M6.5 earthquake in central Idaho on...

We can look back to research describing microbes in Yellowstone hot springs to see how fundamental explorative scientific research is an amazing...

Today, we shed light on what makes up geyser cones.

Our search for eruption precursors focused on gas emissions at Steamboat Geyser. We made repeated measurements over time to look for sudden changes in...

If there were an Olympic medal for hydrothermal systems, Norris Geyser Basin would bring home the gold.

What values do these road-less areas offer for science, for recreation, for wildlife? As public land owners, we all shape the future of the  Greater...

Did you know that there are similar caldera systems spread across the globe? And many of these are far more volcanically active than Yellowstone!

The lack of any basalt in Yellowstone caldera—the existence of a magmatic "shadow"—is good evidence that the rhyolite magma chamber is still at least...

Images acquired using inexpensive cameras from airborne platforms can be used to monitor surface changes in thermal areas over a variety of spatial...

 Yellowstone National Park contains rock formations that span over half the Earth's 4.6-billion-year lifespan! 

Hydrothermal explosions are the most likely of Yellowstone's various volcanic hazards, and the potential for additional future explosions is not...

The U.S. Geological Survey produces seismic hazard maps for the United States and the 2018 nationwide long-term assessment shows that the Yellowstone...

Exploration and sampling of Yellowstone's thermal areas indicates that Yellowstone's hot springs often have surprisingly complex plumbing systems. It...

Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's...

Today, we'll pay homage to one of the scientists that made these discoveries: Dr. Daniel Dzurisin, who retires at the end of this week after over 43...

This preservation mandate made scientific research in YNP initially challenging to sort out—what is the balance between research and preservation, and...

Investigations into the water chemistry of Yellowstone's geysers, hot springs, mud pots, and streams and rivers have been conducted by the U.S...

The arrival of volcanoes in that area is geologically recent, however—volcanism associated with Yellowstone has migrated over 400 miles across...
