"Not all eruptions are Armageddon" - Yellowstone Update for March 2021

Mike Poland, Scientist-in-Charge of the Yellowstone Volcano Observatory, debunks the misconception that if Yellowstone were to erupt, it would be Armageddon. In fact, the most common form of eruptive activity at Yellowstone is a lava flow, and even those aren't that common. They happen only once every few tens of thousands of years.

Lava Enters Halema‘uma‘u Lava Lake, Kīlauea Summit (Feb 17, 2021)

This video shows a close-up of the small inlet where lava enters the lava lake in Halema‘uma‘u crater, at the summit of Kīlauea. The inlet consists of a small upwelling zone, with lava rapidly developing a thin flexible crust as it moves away from the source.

Kīlauea Summit Eruption (Feb 11, 2021)

On February 11, 2021, no major changes were observed at the lava lake within Halema‘uma‘u crater, at the summit of Kīlauea. The inlet site where lava is entering the lake had a small upwelling zone raised slightly above the surrounding lake surface.

Halema‘uma‘u Crater Overflight—Kīlauea Volcano's Summit (Feb 9, 2021)

An overflight today provided aerial views of Kīlauea's ongoing summit eruption. No major changes were observed at the lava lake in Halema‘uma‘u crater. Active surface lava is still largely limited to the western portion of the lake. Snow on Mauna Kea can be seen in the distance.

Halema'uma'u Lava Lake (Using UAS) - Kīlauea Volcano

This video clip from February 4, 2021, shows the erupting west vent and the growing lava lake within Halema'uma'u. The start of this video focuses on the active western portion of the lava lake, which measured approximately 212 m (696 ft) deep at this time. A plume of volcanic gas is seen rising continuously from the west vent. USGS has special use permits from the

Aerial of Halema‘uma‘u Crater, Kīlauea Volcano's Summit

Eruptive activity continues at the lava lake in Halema‘uma‘u crater, at the summit of Kīlauea. This video was taken on February 1 from the morning helicopter overflight. The western fissure supplies lava to the lake at an inlet site along the west lake margin. Activity has been stable in recent days with no major changes.
