Unified Interior Regions

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

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

This Hawai‘i County Fire Department aerial image shows Kapoho Crater with the most active branch of the fissure 8 lava channel now to the west (right) of the cone and feeding a robust ocean entry. The path of the fissure 8 channel prior to being diverted can be seen east (below and left) of the crater; despite no visible surface connection between this branch and the sea,

Sink holes (dark spots to right of large tree) are beginning to form along fractures beneath the field of tephra that has formed downwind of fissure 8. Tephra (Pele's hair and other airborne volcanic glass fragments) from the fissure 8 lava fountains continues to fall downwind, covering the ground within a few hundred meters (yards) of the active vent. High winds can waft

In this aerial view looking to the north, a robust ocean entry plume can be seen rising from just offshore of Ahalanui Beach Park, which was inundated with lava yesterday. Beyond this entry

This time-lapse video shows Halema‘uma‘u and Kīlauea Caldera as seen from the USGS Hawaiian Volcano Observatory. It includes roughly one image for every day between April 14, 2018, and July 11, 2018. The lava lake is visible early in the video, with overflows onto the caldera floor on April 23, but the lake vanishes from sight in early May as pressure in the summit magma

This compilation of video from HVO's early morning overflight of Kīlauea Volcano's lower East Rift Zone shows (1) lava from fissure 8 moving through a perched channel toward the northeast, (2) the diverted channelized ‘a‘ā flow west of Kapoho Crater, and (3) a vigorous ocean entry along the southern coastline in the vicinity of Ahalanui Beach Park (Warm Ponds).

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

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

During an overflight this morning, the Hawaii County Fire Department captured this image looking east toward Kapoho Crater. A breakout from the south margin of the main fissure 8 channel is sending a
