Lava fountaining episode 53 of the ongoing eruption at the summit of Kīlauea began at 3:45 p.m. HST on August 12, 2026. This photo of the fan shaped lava fountain was taken from the Uēkahuna overlook in Hawaiʻi Volcanoes National Park, around 5:00 p.m. HST when the lava fountains were approximately 500 ft (150 m) high. USGS photo taken by M. Cappos.

A wide view of the Uēkahuna overlook in Hawaiʻi Volcanoes National Park, during episode 53 lava fountains of the ongoing Kīlauea summit eruption. The volcanic gas plume rises from the lava fountains as visitors watch the eruption. The ground surface is blanketed in tephra (volcanic rock particles) that were deposited during earlier episodes of this eruption.

Episode 53 of the ongoing episodic Kīlauea summit eruption started on August 12 at 3:45 p.m. HST. The episode 53 lava fountain erupting from the north vent reached heights of approximately 500 ft (150 m) with the gas plume reaching 18,000 ft (5600 m) above sea level.

During the 1926 Mauna Loa eruption, an ‘a‘ā flow about 457 m (1500 ft) wide and 9 m (30 ft) high headed straight for the village of Ho‘ōpūloa on April 17, as shown here. By the next day, the lava flow had destroyed a dozen houses, a church, and the wharf, and had nearly obliterated the bay.

Long before explosive eruptions formed the Yellowstone Caldera and heat from the magmatic system began feeding a dynamic hydrothermal system, there was the Absaroka volcanic range. Remnants of the rugged terrain are still visible on the east and north sides of Yellowstone National Park.

Over the past few decades, an area on the north rim of Yellowstone Caldera has risen and fallen. Just last year a new period of uplift in this area began!

Did you hear that??? Well, Roaring Mountain isn’t quite as loud as it used to be, but it’s still one of the hottest thermal areas in all of Yellowstone National Park!

Meet a friend of ours. This friend has been monitoring changes of the ground surface in Yellowstone for decades and is so good that it can detect movement of just a few millimeters in magnitude (just a fraction of an inch). The friend? A continuous GPS station!

Happy New Year! Let's go back and take a look at the top five geologic stories for Yellowstone in 2025.
Number five: Rumors. It was a year of internet rumors, mostly related to animals fleeing the park, and none of which were true.

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.

Sounds of lava lake activity within Kilauea Volcano's summit vent inside Halema`uma`u Crater on the afternoon of February 14, 2011. The continuous "crashing wave" noise is the sound of churning lava as gases are released from the lake surface, which is in nearly constant motion.

How far did the ash from Mount St. Helens travel?

Kilauea Volcano in Hawaii has experienced its first explosive eruption in more than 80 years and is now spewing noxious gas at 10 times the normal rate. John Eichelberger, head of the USGS Volcano Hazards Program, fills us in on the situation.
