Kīlauea's summit eruption continues on the Island of Hawai‘i; the west vent in Halema‘uma‘u erupts lava into the lava lake. Gas emissions and seismic activity at the summit remain elevated. HVO field crews—equipped with specialized safety gear and PPE—monitor the current eruption from within the closed area of Hawai‘i Volcanoes National Park with NPS permission.

Laboratory experiments help explain what happens when hot rocks, water and gas interact in Yellowstone’s hydrothermal system

Results from laboratory experiments have provided significant insights on many fundamental physical and chemical processes on Earth. They also add insights into the Yellowstone hydrothermal system that could not be obtained otherwise.

Volcano Watch — A closer look at Kīlauea’s newest lava

Every rock on Earth is made of up a unique combination of chemical elements, and lavas/tephra formed during Hawaiian eruptions are no exception. What is the geochemistry of Kīlauea’s newest tephra—and how can it help us understand the processes driving the ongoing eruption

Where do acid-sulfate hot springs come from and why are they important?

Yellowstone hosts thousands of thermal features which have diverse chemistries and origins. The most iconic features, like Old Faithful, have neutral to alkaline pH. Some Yellowstone features, however, can be acidic enough to break down the very rock that hosts them!
