New outcrops make good geology

This aerial view of the western part of Kīlauea Volcano's caldera was taken on August 6, 2018. The down-dropped block is faulted about 120 m (400 feet) below the caldera floor. Many 19th-century lava flows are exposed in the fault scarps. Halema‘uma‘u (not visible) is to the left of this photo.

Lava Fountaining at Fissure 8

During this morning's overflight, HVO geologists observed low levels of lava fountaining within the fissure 8 spatter cone and crusted lava in the spillway and channel downstream. The significance of this change is not yet clear. Eruptions can wax and wane or pause for days to weeks before returning to high levels of lava discharge. New outbreaks in the area of the active

Pāhoehoe Breakout

This lava, erupted from fissure 8 on Kīlauea Volcano's lower East Rift Zone, shows classic pāhoehoe behavior. Exposed to the air, the surface of the flow chills to form a thin crust that can be stretched or broken apart, forming pieces of crust that are "subducted" back into the molten interior. The main sound is wind noise, but crackles can also be heard as flakes of

fissures were characterized by low eruption rates

During the first two weeks of Kīlauea Volcano's 2018 lower East Rift Zone eruption, fissures were characterized by low eruption rates and small flows. This was because the erupted lava originated from pockets of cooler, less fluid magma stored in the rift zone. Later fissures erupted hotter, more fluid magma, resulting in higher eruption rates and large, fast-moving lava

Collapse at Kīlauea (July 24, 2018)

A collapse event occurred at the summit of Kīlauea this morning (July 24, 2018) at 6:41 a.m. HST, releasing energy equivalent to a magnitude-5.3 earthquake, which is similar to that released by previous collapse events. In this video, watch as today's event unfolds from the perspective of HVO's live-stream camera. At 6:41:08 (time stamp at upper left), a small tree along

July 14, 2018, Kīlauea fissure 8 video captured by UAS

In this July 14, 2018, video captured by the UAS (Unmanned Aircraft Systems) team, lava was erupting from within the 120-foot-high fissure 8 cinder cone built of chilled lava fragments. Lava emerging from the cone was traveling about 13-16 miles per hour, flowing freely over a small set of cascades (rapids) and into a perched channel that was as much as 50 feet above the

Kīlauea Volcano's summit (DEM)

Since early May 2018, the floor of Halema‘uma‘u Crater has dropped 450 m (about 1480 ft). Extensive cracking and faulting around the crater, along with inward slumping of the crater rim, has more than doubled its diameter. Like a balloon slowly losing air, subsidence occurs because magma in Kīlauea's shallow summit reservoir is moving into the East Rift Zone more rapidly

Rockfalls and Sounds

Listen to the sounds of rockfalls at Kīlauea Volcano's summit in this short video taken from the northeast rim of the caldera. At 2:42 p.m. HST on July 12, 2018, a collapse/explosion event at Kīlauea's summit released energy equivalent to a magnitude-5.3 earthquake. Rockfalls that occurred in Halema‘uma‘u and along the steep summit caldera walls during the event can be

Four Examples of Nest Predation by Rats - Hawaii Volcanoes National

Black rats were unintentionally introduced to Hawai’i in the late 1800s, most likely as hitchhikers on trading vessels. Since their introduction, they have disrupted native ecosystems by destroying native plants, eating native arthropods, and depredating bird nests. Black rats have contributed to population declines and species extinctions of Hawaiian forest birds, and
