Eruptions of lava in the Lower East Rift Zone of Kīlauea Volcano began late afternoon on May 3 in a part of Leilani Estates subdivision. Over the course of the eruption, 24 fissures have erupted lava. Fissure 8 has been the dominant source of lava fountains that feed channelized lava flows reaching to the eastern shore at Kapoho.
Minor explosive eruptions of ash at the Kīlauea summit continue. Columns of ash and volcanic gas are occasionally injected into the atmosphere between 10,000 and 30,000 ft above sea level.
Hawaii County Civil Defense is coordinating notifications for public safety. USGS Hawaiian Volcano Observatory scientists are monitoring various data 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.
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.
