The beautiful Morning Glory pool is located near Old Faithful. However, it has changed over time because of people and past climate. But how?

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 an overflight at approximately 6 a.m., USGS Hawaiian Volcano Observatory geologists observed the fissures system that opened on the upper portion of the Southwest Rift Zone early this morning. Approximately half a mile (about 1 km) in length, only the southwest portion of the system was active by daylight.

USGS Hawaiian Volcano Observatory geologists visited the fissure that formed on the upper Southwest Rift Zone of Kīlauea volcano early this morning, June 3, 2024. Elevated gas emissions are being carried downwind, in a southwest direction. USGS video.

Mount St. Helens and Yellowstone are two of the most well-known volcanoes in the United States. They have some pretty obvious differences, but they have some similarities as well. So, just how similar are Mount St. Helens and Yellowstone?

Mt St. Helens before 1980, Land of Transformation
A stylistic interpretation of pre eruption snowcapped Mount St Helens as seen from a blue Spirit Lake with green rolling hills.
Text changes to May 18, 1980, Eruption. There is a grey explosion of rocks and smoke coming out the top of Mt St Helens. The hills and water are grey and brown.

Volcanic ash in Kansas? It's true there's thick deposits there, but where are the source volcanoes? Geologists began puzzling over this in the late 1800s when these deposits were first recognized.

If a geyser erupts and no one is there to hear it, does it make a sound? Of course it does, and now we can hear it no matter when it happens thanks to a new monitoring station in Yellowstone National Park.

Steamboat Geyser is the tallest geyser in the world. It has been putting on a show the last few years for visitors at Yellowstone National Park with a record number of water eruptions, 48 eruptions each in 2019 and 2020. But it's only had eight eruptions in 2023. Is Steamboat losing steam?

Lava flows are one of the coolest (or maybe hottest!) features about volcanoes, but what would a lava flow look like if you could peel away the surface and take a peek underneath?

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.

Several vents continued to erupt on the western side of the downdropped block within Kīlauea's summit caldera on September 6, 2023. The roughly east-west trending active vents span approximately 0.5 miles (750 m) and had lava fountain heights of up to about 10 meters (32 feet).

During an HVO eruption monitoring overflight on September 12, 2023, HVO geologists landed on the downdropped block within Kīlauea's summit caldera and searched for a safe place to collect a lava sample.
