Caldera Chronicles

Yellowstone is one of the best instrumented volcanoes in the world. There are several dozen GPS stations, seismometers, temperature sensors, river...

Three YVO scientist communicators joined up with a university social scientist and earthquake-science communicator to offer a short course on...

Multiple hydrothermal breccia pipes are exposed along the northern and western shores of Yellowstone Lake and provide clues into the shallow roots of...

The backbone of Yellowstone's ground-based monitoring network consists of seismic stations, which detect earthquakes, and GPS (Global Positioning...

Let's ditch the overused, misrepresentative, and misapplied "supervolcano" term. Instead, let's call them "caldera systems."

YVO gets a lot of questions about whether Yellowstone, or another caldera system, will end all life on Earth. The answer is—NO, a large explosive...

"It's been two years now since I stepped away from YVO, and I wanted to take this time to reflect a bit on my experiences with the observatory and as...

Geoscientists have never observed an active magma reservoir firsthand because magmas are stored inaccessibly deep underground. However, crystals are...

Yellowstone National park hosts more than 10,000 hydrothermal features including hot springs, geysers, fumaroles, and mud pots. But did you know that...

USGS and Yellowstone National Park scientists visited a newly discovered thermal site in the park. They mapped the extent of the area and took the...

Scientists who work at Yellowstone are interested in finding physical and chemical signals from the deep magmatic system, both to better understand...

What does cause an eruption at volcanoes like Yellowstone? To answer this question, we look at small crystals that formed in erupted volcanic rocks!

How long has the magma chamber existed? And how can we explore such a complex question, given that we can't directly see several kilometers deep...

Have you ever wondered why geysers are rare and what causes them to erupt? And why scientists study geysers?

During the Spring term in 2019, geology students from Montana State University participated in a reading group focused on understanding the geology of...
