"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.

February 26, 2021—Kīlauea summit eruption contour map

This map of Halema‘uma‘u at the summit of Kīlauea shows 20 m (66 ft) contour lines (dark gray) that mark locations of equal elevation above sea level (asl). The map shows that the lava lake has filled 218 m (715 ft) of the crater, to an elevation of 735 m (2411 ft) asl since the eruption began at approximately 9:30 p.m. HST on December 20, 2020. Contour lines highlighted

Close-up view of active lava flow Halema‘uma‘u, February 24, 2021

In the morning of Tuesday, February 23, a new source of spatter appeared on flank of the active western fissure within Halema‘uma‘u at the summit of Kīlauea. It started to feed a short lava flow down the spatter cone and onto the crusted northwest margin of the lava lake. A field crew on Wednesday observed the flow to be active, and captured this photo through the lens of

View of Halema‘uma‘u lava lake from the west, February 24, 2021

On Wednesday, February 24, HVO scientists observed the Kīlauea summit eruption in Halema‘uma‘u from the west rim of the crater. In this photo, the active western fissure is marked by an incandescent skylight on the near side of the lava lake. A plume of sulfur dioxide and other volcanic gases rises constantly from the fissure as it effuses lava into the lake, which

Eruption in Halema‘uma‘u crater - February 24, 2021

A telephoto image of the small lava flow from the western fissure within Halema‘uma‘u, at the summit of Kīlauea. Occasional incandescence was visible (center) from the weakly active flow on the northwestern lava lake levee. A portion of the active lava lake is visible in the lower-right. This photo was taken within an area of Hawai‘i Volcanoes National Park that remains

Western vent in Halema‘uma‘u crater - February 24, 2021

 A telephoto image of the western fissure within Halema‘uma‘u crater, at the summit of Kīlauea Volcano. On Wednesday, February 24, 2021, the northern-most vent of the fissure was producing occasional weak bursts of spatter (center). This vent fed a new lava flow which was emplace between the spatter cone and the crater wall and advanced a short distance along the

Active surface lava remains limited to the western portion of the lake, shown here as seen from the south rim of the crater and looking towards the northwest. The western fissure cone is in the center of the photo. The top of the main cone is obscured by volcanic gases, and a small glow area is
