HONOLULU — Park rangers have cited dozens of people who have gathered at Hawaii Volcanoes National Park to witness an ongoing eruption of the Kilauea volcano.
‘Twas the Sunday before Christmas, the eve of the winter solstice, and festive holiday lights blinked of bright red and green. And then, shortly after 9:30 p.m. on Dec. 20, so did the Hawaiian Volcano Observatory’s (HVO’s) volcano alert level/aviation color codes for Kilauea!
Two vents continued to feed lava into a rapidly enlarging lava lake filling Halema‘uma‘u crater, the Hawaiian Volcano Observatory said.
After months of nearly nonexistent business because of COVID-19, one tour company has seen an uptick in bookings since Sunday’s eruption commenced at Kilauea Volcano‘s summit.
West Hawaii residents awoke Tuesday to a blanket of vog for the first time in more than two years.
After feeling the biggest earthquake of his life, Kyle Nolan knew something dramatic was happening.
Update: The Hawaiian Volcano Observatory reports the lava lake within Halemaumau crater continues to rise.
The 2018 Lower East Rift Zone eruption and summit caldera collapse marked the end of the 35-year-long Puu Oo and 10-year-long summit lava lake eruptions, and the beginning of a new chapter in Kilauea Volcano activity. The volcano is continuing to behave in ways that are a response to the major events of 2018 and “the new normal” is yet to be defined.
Though there hasn’t been an eruption in Hawaii in 2020, the year has hardly been quiet—earthquake swarms, an elevated alert-level on Mauna Loa, and a growing water lake on Kilauea are reminders that island residents should be aware of Hawaii’s active volcanoes.
Tephra is the Greek word for ash, and it is the label we use for rocks that come flying out of the volcano during an eruption. Every feature of every single tephra grain has something significant to say about the volcanic process that created the grain and the transport journey it took afterward.
Kilauea Volcano’s 2018 eruption was triggered by a relatively small and rapid change at the volcano after a decade-long build-up of pressure in the upper parts of the volcano, according to a recent study published in Nature Communications by earth scientists from the University of Hawaii at Manoa and U.S. Geological Survey.
While this scenario describes the highly destructive 2018 eruption on the lower East Rift Zone (LERZ) of Kilauea, it also pertains to an earlier event on the East Rift Zone: the Thanksgiving Eve Breakout (TEB) lava flow in 2007.
Modeling topography on active volcanoes is unlike doing so in any other setting, because dramatic changes can occur on timescales far shorter than a human lifetime. For example, in 2018 at Kilauea, approximately 1 cubic kilometer of rock volume (0.25 cubic miles) was lost at the volcano’s summit and deposited on the lower East Rift Zone. So, topographic models can become outdated relatively quickly, and we need to update them accordingly.
The U.S. Geological Survey has five volcano observatories tasked with monitoring low to high threat volcanoes throughout the United States.
Famous for glowing red lava and billowing volcanic plumes, Halemaumau has long inspired poets, painters and photographers to find meaning in the color and light of this dynamic landscape.
