This photo shows the eastern portion of Halema‘uma‘u, at the summit of Kīlauea. The circular area of yellow coloration, near the top of the photo, is spot where the first lava fountain emerged in the September 2023 eruption. In the lower portion of the photo, the remains of Crater Rim Drive and the Halema‘uma‘u parking lot are visible.

HVO geologists made a routine visit to check on equipment at the summit of Kīlauea today, and had clear views across the floor of Halema‘uma‘u. The central portion of this photo is the region where much of the lava lake activity has occurred over the previous few years, with the area now showing only wispy plumes of weak gas emission.

HVO geologists observed the new eruption within Kīlauea summit caldera during an eruption-monitoring overflight the morning of September 11, 2023. Multiple minor fountains remain active in the eastern portion of Halema‘uma‘u crater floor and on the downdropped block within Kīlauea's summit caldera.

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?

Sounds of lava lake activity within Kilauea Volcano's summit vent inside Halema`uma`u Crater on the afternoon of February 14, 2011. The continuous "crashing wave" noise is the sound of churning lava as gases are released from the lake surface, which is in nearly constant motion.

Kilauea Volcano in Hawaii has experienced its first explosive eruption in more than 80 years and is now spewing noxious gas at 10 times the normal rate. John Eichelberger, head of the USGS Volcano Hazards Program, fills us in on the situation.
