Caldera Chronicles

A long-told myth about Yellowstone is that indigenous people were “afraid” of the area owing to the geysers and thermal activity. But archeological...

Every heard of a thermal kame? If not, you’re hardly alone. It’s a rare landform that provides evidence of glaciers interacting with hydrothermal...

What causes outliers in GPS data? Could be snow, could be a bird, or could be damaged equipment. Recognizing these outliers is important to properly...

Thanks to a newly funded project from NASA’s Commercial SmallSat Data Scientific Analysis Program, and an agreement with commercial satellite...

Reporting of earthquakes at volcanoes around the world varies considerably in style. This is because the amount and importance of seismic activity...

Although it is a common assumption that animals cause numerous wounds and deaths in Yellowstone, hot springs actually account for more injuries and...

Geologic maps are a fundamental tool for earth scientists to assemble and communicate geologic information. Under the umbrella of geologic mapping are...

Scientists can determine the sources of hydrothermal fluids in park rivers by monitoring water chemistry. The result? A “budget” of which geyser...

A small lake near Norris Geyser Basin has seen some significant changes over the past few years, rising in level and changing color due to inputs of...

What can trees tell us about Steamboat Geyser’s history? Why do Steamboat’s seismic eruption signals vary seasonally? Get up to speed on two newly...

Data from a major deployment of seismometers in 2020 is revealing new insights into the characteristics of the magma chamber beneath Yellowstone...

Long before the boardwalks, hotels, and roads, Yellowstone stood on the edge of the American wilderness. Its discovery and exploration by Euro...

Based on geologic mapping and dating of minerals, we know that the Yellowstone caldera formed 631,000 years ago. But how did the caldera collapse...

New satellite communication technology is being tested at Yellowstone monitoring stations and could have a big impact on how real-time data are...

The Yellowstone volcanic system has hosted some very large eruptions. But there have been much larger volcanic explosions in geologic history...

Yellowstone gets rattled by plenty of small earthquakes—between 1,500 and 2,500 located events in a typical year—but large damaging earthquakes have...

Locating an earthquake in an absolute sense can come with considerable uncertainty, but locating earthquakes relative to one another is far more...

Geyser Hill, near Old Faithful, has experienced some recent changes, with a general increase in thermal and geyser activity. The changes are...

Monitoring data from Yellowstone are not just useful for assessing the potential for volcanic eruptions there.  We can also use what we learn from...

Although Yellowstone Caldera might be better known, the slightly older Valles Caldera, in New Mexico, was where some of the fundamental...
