Their goal was to sample tephra deposits from the crater wall, which had been inaccessible before now. As lava flows have filled in Halemaʻumaʻu, the floor of the crater has risen but the deposits, records of past explosive eruptions in Kīlauea’s history, could be covered by lava flows in the future.
These samples were collected with permission from Hawai’i Volcanoes National Park and will help us better understand eruption behavior, magma storage, and volcanic hazards.

**Yellowstone Volcano Observatory monthly video update – August 1, 2026**
The Norris Uplift Anomaly is an area along the north rim of Yellowstone Caldera, just south of Norris Geyser Basin and in the vicinity of Gibbon Falls. In the late 1990s to early 2000s, it was found to be uplifting at a rate of a couple of inches per year. After that, it subsided slightly. Subsequent periods of minor uplift occurred in the mid 2010s and early 2020s. Most recently, a new period of uplift began suddenly in June/July 2025. The uplift was detected by continuous GPS stations, semipermanent GPS station (which are installed for a few months every summer to densify the ground deformation monitoring network), and satellite radar measurements.

Episode 52 of lava fountaining began at 7:10 p.m. HST on July 28, 2026, after low dome fountains and lava flows from the north vent throughout most of that day. The episode ended after about 7.5 hours, with the lava fountain from the north vent reaching a maximum height of about 500 feet (150 meters) at around 9 p.m. An estimated 6.1 million cubic yards (4.7 million cubic meters) of lava erupted in total.
The eruption plume reached about 19,000 feet (5,800 meters) above sea level. Winds were out of the northeast for the most energetic of the eruption, causing the plume to move to the south. Most tephra fell in the closed area of Hawaiʻi Volcanoes National Park.

As we pass that dome, looking at it on the left side of the frame, the overlapping and taller 2004-2008 lava dome comes into view. We circle around the back of the crater, with a view of the jagged crater walls and the glacial ice below. As the view swings around to the north and we look out over the lava domes, we can see that the 2004-2008 dome is still steaming in places! Beyond the crater we can see Spirit Lake (where logs from 1980 still float on the water), Johnston, Ridge, and Mount Rainier looming in the distance.

*Yellowstone Volcano Observatory monthly video update – July 1, 2026*
On July 23, 2024, Biscuit Basin was the site of a significant hydrothermal explosion. Just before 10 am that day, an explosive event from Black Diamond Pool sent rocks flying, destroying a nearby boardwalk but fortunately not causing any injuries. The explosion was caused by pressure changes in the hot water plumbing system just beneath the surface, with hot water flashing to steam and driving the activity. To monitor the area, the Yellowstone Volcano Observatory installed several new sensors after the explosion. On June 13, 2026, that monitoring equipment detected significant seismic and acoustic energy, with video observations catching a jet of steam coming from new features that opened s...

The activity was recorded by a camera and other monitoring equipment and resulted in major changes to the landscape, including a 18.5-meter (61--foot) fissure full of boiling water. Rocks were thrown a short distance from the vents.
About 2 or 3 days later, a circular collapse feature with a pool of near-boiling water formed in the area of the explosion. That pool was observed to spout water to heights of 6-9 meters (20-30 feet) intermittently on June 18.

Some of the most common questions are about the temperature of the water. Geysers are all boiling, but the temperature of hot springs can vary from lukewarm to almost boiling. Mammoth Hot Springs has no boiling water because the water takes a very long journey from the heat source beneath the caldera. So there are no geysers in Mammoth Hot Springs because there's no boiling water.
Acidity also varies by thermal area. Mud Volcano is more acidic than fe...

**Yellowstone Volcano Observatory monthly video update – May 1, 2026**
Roaring Mountain is located along the highway between Mammoth Hot Springs and Norris Geyser Basin. In the late 1800s, the sounds of gas escaping could be heard for miles, but that diminished by the beginning of the 1900s. Then, in 1902, there was a thermal event that brought the sound back once again! Heat emissions increased, and trees died off over a broad part of the thermal region.

**Yellowstone Volcano Observatory monthly video update – April 1, 2026**
Lone Star is not just an iconic movie hero of the 1980s (and also next year!). It’s an iconic Yellowstone geyser as well!
Lone Star Geyser is a classic cone-type geyser. The cone is made of silica sinter. Silica is dissolved in the hot water that moves beneath the surface, and as the water rises and erupts the sinter is deposited to form a cone. Lone Star erupts about every three hours on average—a pattern that has been consistent since at least the 1880s. That’s more consistent than Old Faithful!
Lone Star Geyser eruptions start with minor activity before sending a plume of water and steam up nearly 50 feet for as long as tens of minutes. A steam phase follows—that’s what you're seeing in this video.

KABOOM! That’s what Yellowstone is famous for – huge explosive volcanic eruptions. There’s really nothing brewing right now, the magma chamber is mostly solid, but there have been quite a few hydrothermal eruptions and small explosions in both Biscuit Basin and Norris Geyser Basin as water in the hydrothermal system flashes to steam.
A curious new blue water pool formed in Norris Geyser Basin in late 2024 to early 2025 via a series of small explosions that threw out rock and excavated a small crater. This sort of activity is nothing new, as thermal features are commonly activating and going quiet across Yellowstone National Park.

- 💰Gold in the trash? Not quite. But we are rethinking mine waste as a resource.
Across the U.S., legacy mining sites have left behind open pits, shafts, and extensive tailings piles. Historically considered waste, these materials might contain critical minerals and other minerals.
These minerals are essential to modern technologies—powering everything from smartphones and electric vehicles to medical devices and defense systems. Many occur alongside commodities like gold, zinc, and coal.
USGS scientists are using advanced geochemical and geophysical methods to characterize mine waste and assess its potential as a secondary source of critical minerals.
It’s part of a broader effort to reduce reliance on imported materials and support a more secure, domestic mineral supply chain.

- Description
- In May 2025, record rainfall in Australia's New South Wales created major flooding along the coast. In Taree, a mid-North Coast city, the Manning River reached a height of 6.4m on May 21st. The previous record of six meters was set back in 1929. The torrential rains have left almost 800 properties and counting uninhabitable in New South Wales.
South Australia was hit in late March through early April 2025. Extensive rainfall in Queensland in March sent floodwaters down the Kinipapa (or Cooper Creek) into the South’s outback township of Innamincka. Landsat images show the area before and during the flooding. Pasturelands, settlements, and protected national areas became inundated with floodwater, prompting massive road and park closures. The water levels peaked around 14.5m, a little over 47ft, near the Innamincka Causeway, surpassing the previous flood record set in 1974.

In 2016, USGS collaborated with NASA, Arizona State University, Carnegie Institution for Science, and the Johns Hopkins University Applied Physics Laboratory to produce the first high-resolution topographic map of Mercury. The map captures the planet’s craters, volcanoes, and tectonic features in remarkable detail.
To make this possible, USGS scientists developed advanced software and innovative techniques to process massive amounts of spacecraft imagery. Using more than 100,000 images from NASA’s MESSENGER mission, they identified Mercury’s landforms and precisely aligned the images to create a seamless digital map of the entire planet.
By mapping planetary landscapes, we learn more about planetary evolution, tectonics, and even Earth’s own geologic past.

- Description
- Exotic annual grasses, or EAGs, are invasive species. They outcompete native grasses. They are extremely flammable. And they are expanding into higher elevations. Targeted sheep grazing is one way to combat these invasive grasses, manage fire risk, and help restore native sagebrush in western states.
The EROS team releases weekly EAG maps during the peak green-up in late April to early June, along with annual phenology maps to show the seasonal timing of the green-up. Dr. Kelly Hopping at Boise State University is using these maps to see whether targeted sheep grazing can help manage EAGs. The maps help researchers work with sheep producers to know when is the best time to move the sheep into those areas so their grazing can do the most good. The sheep then, as a part of the team solving the problem of invasive grasses, get to eat in the field when they might not otherwise have grazing available.

Here's how:
🧪Streams become polluted. USGS tests water for contamination, informing water treatment plants so they can adjust filtration.
💧Burned soil becomes water-repellent. USGS maps burn scars to predict where postfire flooding & debris flows will happen.
🪨Slopes become unstable. USGS maps landslide-prone areas and works with the National Weather Service to issue early warning alerts for communities.
🪴Invasive plants can grow. USGS studies how different environments recover & provides guidance on reforestation efforts.

- 🌋Today marks the 45th anniversary of one of the most dramatic geologic events in American history - the May 18, 1980 eruption of Mount St. Helens.
After lying dormant for over a century, signs of unrest for the eruption begin in March of that year when a swarm of earthquakes shook inside the mountain. With each tremor a new pathway was opened for the magma and volcanic gases to rise upwards.
As the weeks passed, pressure built within the volcano causing the north flank to bulge ominously.
Then, on the morning of May 18, the slope gave way in a massive landslide—followed instantly by a devastating lateral blast.
Traveling at over 650 mph, the eruptive blast flattened 230 square miles of pristine Pacific Northwest wilderness. Volcanic mudflows, known as lahars, surged through valleys, carrying debris all the way to the Columbia River. Ash from the eruption rose high into the atmosphere and drifted east, eventually reaching as far a...
