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

Kīlauea Volcano — Landscape Differences

During HVO's morning overflight today, the dramatic difference in landscapes on the northern and southern sides of the fissure 8 lava channel was readily apparent. With dominant trade winds blowing heat and volcanic gases to the southwest, the north side of the lava channel remains verdant, while, in stark contrast, vegetation on the south side has been severely impacted

A whirlwind spins skyward on the northwest side of the fissure 8 cinder cone in this video taken on July 10, 2018. A number of whirlwinds have formed in the area due to the extreme heat of the open lava channel heating the air above it. As the heated air quickly rises, a light wind can push the air column to begin a rotation, which spins faster as it is stretched and

Last week's Volcano Watch focused on the East Rift Zone eruption, which continues to impact the lower Puna District on the Island of Hawai‘i. Changes in the eruption are occurring daily, if not hourly, so by the time you read this article, the situation will likely have changed. Nevertheless, here's the status of the eruption as of Friday, May 11 (when this was written):
