Hawaii versus Yellowstone (Yellowstone monthly update - December 2025)
Hawaii versus Yellowstone (Yellowstone monthly update - December 2025)Just last week, Kīlauea put on another dramatic display of lava fountaining and flows within the caldera, during its 37th episode of this most recent eruption. It doesn't seem like Hawaii and Yellowstone have a lot in common, but actually, those two magmatic systems have a common cause.

Emergency fix at a Yellowstone monitoring site (Yellowstone Monthly Update October 2025)
Emergency fix at a Yellowstone monitoring site (Yellowstone Monthly Update October 2025)The Yellowstone caldera is vast – 45 miles across by 30 miles wide. You could fit over 60 islands of Manhattan in this area. There are deep canyons, like the one on the Yellowstone River, that reveal a complex geologic history. And, forested landscapes and features remind us that this special place is ever-changing.

August 5, 2025 — Lava flowing in the north vent
During a USGS Hawaiian Volcano Observatory helicopter overflight on the morning of August 5, geologists observed a lava pond within the north vent of the ongoing Kīlauea summit eruption. The pond was feeding a subterranean lava tube contained within the east side of the vent cone, toward the floor of Halema‘uma‘u crater.

A year since the Biscuit explosion… are animals leaving the park? (Yellowstone Monthly Update August 2025)
A year since the Biscuit explosion… are animals leaving the park? (Yellowstone Monthly Update August 2025)Just over one year ago, early morning visitors to Yellowstone’s Black Diamond Pool suddenly found themselves filming a spectacular event. The July 23, 2024 hydrothermal explosion threw material hundreds of feet high, including rocks that were a foot or more across.

Two video cameras are installed atop a utility pole near the northernmost point of land in the United States at Nuvuk (Point Barrow), Alaska. The cameras point northwest toward the Arctic Ocean and the boundary between the Chukchi and Beaufort Seas. Every half hour during daylight hours, the cameras collect snapshots and video for 10 minutes.
