Kīlauea Volcano's summit, as viewed from the southwest, shows the collapsed area of Halema‘uma‘u and the adjacent caldera floor. A section of Crater Rim Drive preserved on a down-dropped block is visible at the far right. Volcanic gases rising from magma stored beneath the summit continue to escape to the surface, as they have for as long as Kīlauea has existed, resulting in deposits of sulfur on the crater walls.

A slight inflationary trend near and east of Puʻu ʻŌʻō suggests that magma may be refilling the middle East Rift Zone. Low seismicity and reduced gas emissions do not indicate that the magma is shallow, but HVO continues to closely monitor this area and will report any significant changes.

Low sulfur dioxide gas emissions on Kīlauea have resulted in greatly diminished vog (volcanic air pollution) in Hawaii, giving rise to spectacular views on the island. Here, looking across the field of lava erupted from Kīlauea's lower East Rift Zone this past summer, the shield-shaped profiles of Mauna Loa (left) and Mauna Kea (right) can be clearly seen in the far distance.

Volcano Watch: Kilauea activity update for October 11, 2018

Kīlauea activity is greatly reduced, with low rates of seismicity, deformation, and gas emissions recorded this past week, and no active lava at the surface of the volcano since September 5.

This comparison shows the area of Kapoho before and after. Kapoho Crater is in the left portion of the image. Lava filled much of the crater, including the small nested crater that contained Green Lake. The Kapoho Beach Lots subdivision is in the right side of the image, north of Kapoho Bay, and was completely covered by the fissure 8 lava flow. Vacationland Hawai‘i, in the lower right corner of the image, was also completely covered, along with the adjacent tide pools. Kapoho Farm Lots, near the center of the image, is also beneath the flow. For a map of the 2018 lower East Rift Zone eruption fissures and surrounding area, see the HVO web site

Volcano Watch: Kilauea activity update for October 4, 2018

Active lava has not been seen within the fissure 8 cone since September 5, and the high rates of seismicity and deflationary deformation at the summit stopped abruptly on August 4.

Volcano Watch: Kilauea activity update for September 27, 2018

At Kīlauea’s lower East Rift Zone, the most recent significant incandescence visible within the fissure 8 cone was on September 15. At the summit of the volcano, seismicity and ground deformation remain low.

Volcano Watch: Kilauea activity update for September 20, 2018

The combined sulfur dioxide emission rates at Kīlauea’s summit, Puʻu ʻŌʻō, and lower East Rift Zone remain at less than 1,000 tonnes per day—lower than at any time since late 2007.

Kilauea Eruption: Volcano still fairly quiet, Civil Defense discontinues daily updates

The Hawaiian Volcano Observatory reports that activity on the lower east rift zone of Kilauea Volcano has diminished and remained quiet for over a week. The only surface activity is a small, crusted lava pond inside the fissure 8 cone, and a few areas along the coast where lava is entering the ocean. Sulfur dioxide […]
