Like the “Did You Feel It?” earthquake reporting tool helps make maps of areas affected by shaking, the new tool helps scientists map areas affected by tephra fallout; observations will be used to assess the character and size of the eruption plumes from Kīlauea volcano on the Big Island, along with the dispersal pattern of tephra fall.

The U.S. Geological Survey’s Hawaiian Volcano Observatory website is currently offline due to a widespread issue affecting USGS public websites.

Strong updrafts coupled with light winds blowing to the east and north sent lava fragments — called tephra — from those molten rock geysers over much of Puna, into Hilo and falling along the eastern edge of Kaʻū; learn more now!

More than 320 “Felt Reports” were made within the first 45 minutes after the temblor, with it being felt widely around the Big Island; aftershocks are possible within the coming days to weeks.

Episode 41 erupted Saturday morning and lasted more than 8 hours before abruptly ending just before 7:30 p.m.

Since the ongoing eruption began a year ago, the Kīlauea summit region has been remarkably quiet from an earthquake standpoint, but that is changing.

The fair on Jan. 24 is in partnership with the Ocean View Resilience Hub and the Hawaiian Volcanoes Education and Resilience Institute.

Ongoing swarms of earthquakes and persistent volcanic tremors indicate active magmatic movement, fueling anticipation about Kīlauea’s next eruption.

After nearly 10 hours, Episode 40 of the Halemaʻumaʻu eruption comes to a sudden end.

While the mid-20th century episodic eruption and current ongoing eruption within the summit caldera of Kīlauea volcano on the Big Island share similarities, there also are several differences.

The scheduled operations including projects for invasive species control, aerial mapping of vegetation, seed collection and more; the park “regrets” any noise impact to residents and visitors.

Often spotted by onlookers in Hawaiʻi Volcanoes National Park, or even by YouTube livestream viewers, the long, ashy gray or brown, ropy cloud-like structures tend to appear near or downwind of active lava fountains.

On the one-year anniversary of Kīlauea’s rare episodic eruption, viewers watching the live feed at the summit were shocked to see two men walk in front of the camera that is in a restricted area.

The most recent eruptive event at the summit of the Big Island lasted about 8.1 hours less than the first episode that started the eruption a year ago on Dec. 23, 2024, but produced higher fountains and more lava output.

The rare ongoing eruption within Halema’uma’u Crater inside the summit caldera of the Big Island volcano began Dec. 23, 2024, with Episode 39 expected any day now.

Hawaiʻi health officials have issued a warning about deteriorating air quality due to lingering volcanic gases from Kīlauea, urging residents and visitors to limit exposure to the vog.

Hawaiʻi Volcanoes National Park rangers want visitors to have a safe and memorable adventure this holiday season. Safety is their top priority, but it is your responsibility.

Scientists at the Hawaiian Volcano Observatory, in collaboration with the U.S. Geological Survey, have installed a new livestream monitoring camera at Kīlauea on the Big Island.

Join Hawaiian Volcano Observatory staff and its partners Hawaiʻi Volcanoes National Park, University of Hawaiʻi at Hilo and Hawaiʻi County Civil Defense in January 2026 for a series of programs around the island that will discuss eruptions and earthquakes, how Hawaiian Volcano Observatory scientists monitor them and the hazards associated with them.

At 10 a.m., livestream cameras from the U.S. Geological Survey showed smoke billowing out of the Halema‘uma‘u Crater.
