Eruption in Leilani Estates subdivision, Kīlauea Volcano Hawaii
The intrusion of molten rock into the lower East Rift Zone of Kīlauea Volcano reached the surface in the late afternoon on May 3 in a part of Leilani Estates. A fissure about 150 m (492 ft) long erupted mostly spatter and intermittent bubble bursts for about 2 hours. Lava did not travel more than a few m (yards) from the fissure.
Hawaii County Civil Defense
is coordinating needed response including evacuation of a portion of the Leilani subdivision. USGS Hawaiian Volcano Observatory
deployed geologists to the eruption site overnight, and other scientists are monitoring various data streams telemetered to the observatory 24/7. Check the Kīlauea webpages
for new information (updates, photos, maps). Updates will be sent out as new information is gathered and as new outbreaks of lava occur.
Read Our Two Weekly Volcano Observatory Science Articles
Scientists within the USGS Volcano Hazards Program operate from within five U.S. volcano observatories. One of the primary goals of the observatories is to be an authoritative source for enlightening information about our Nation's volcanoes.
The Hawaiian Volcano Observatory (HVO), the oldest of the five, has a long history of writing regular articles about volcanic activity and scientific research on the Hawaiian volcanoes. HVO's weekly article, "Volcano Watch," entered its 27th year of publication in November 2017. The entire catalog of articles can be accessed and searched on their website. New articles are published every Thursday afternoon.
Taking lead from HVO, the Yellowstone Volcano Observatory (YVO), the newest of the five observatories, began a weekly article on the first day of 2018. This new column—the "Yellowstone Caldera Chronicles"—is posted each Monday on the homepage of YVO's website . Like HVO's Volcano Watch series, the YVO Chronicles are peer-reviewed and edited before publication.
If you are interested in learning more about a specific topic related to Yellowstone or Hawaiian volcanism, please contact us. We will certainly answer, and you may see a longer-winded answer in a future Volcano Watch or Yellowstone Caldera Chronicle article.
Volcanic Unrest is Persistent in Alaska and Hawaii
The Alaska Volcano Observatory website (AVO) includes complete information about volcanoes in Alaska.
The Hawaiian Volcano Observatory website offers information about volcanoes in Hawaii.
- Mount Cleveland, located in the central Aleutian Islands, has been in a state of volcanic unrest since June 17, 2015. Explosive eruptions can send ash to altitudes hazardous to aviation.
Kīlauea Volcano on the Island of Hawai‘i has been erupting from its East Rift Zone nearly continuously since 1983. Lava flowing into the Pacific Ocean presentsocean entry hazards to visitors. A second eruption began at the summit of Kīlauea in 2008 where an active lava lake produces occasional explosions and gas emissions that create Statewide vog hazards.
Mauna Loa Volcano on the Island of Hawai‘i began showing signs of unrest in 2014, and the volcano alert level and aviation color code were raised on September 17, 2015. Elevated rates of earthquakes and ground deformation persist and HVO continues to monitor the volcano closely.
