Volcanic threat assessment helps prioritize risk reduction efforts at U.S. volcanoes
October 25, 2018
Since 1980, there have been 120 eruptions and 52 episodes of notable volcanic unrest at 44 U.S. volcanoes. When erupting, all volcanoes pose a degree of risk to people and infrastructure. However, the risks are not equivalent from one volcano to another because of differences in eruptive style and geographic location. …In Hawai‘i, Kīlauea and Mauna Loa are ranked as very high threat volcanoes, and Kīlauea is in the number one spot for the nation.

How you can stay informed about Kīlauea Volcano activity

The USGS Volcano Notification Service
(VNS) is a free service that sends automatic notices (emails or texts) about volcanic activity at U.S. monitored volcanoes, including Hawaiian volcanoes. You can sign up to receive these notifications at http://volcanoes.usgs.gov/vns/
Through VNS, the Hawaiian Volcano Observatory issues:
- daily Kīlauea eruption updates,
- weekly Mauna Loa updates,
- monthly updates for Hualālai, Haleakalā, and Mauna Kea,
- Status Reports about volcanic activity during ongoing events,
- Volcano Activity Notices if/when significant events or changes in volcanic activity or alert levels occur, and
- Information Statements to provide additional information or explanations of non-volcanic events on an "as needed" basis.
You can choose the types of notifications that you wish to receive—all of them or just some of them. You can also select the volcanoes you want to hear about—you can choose Hawai‘i only, or volcanoes in other states as well.
For more information about these types of notifications, please see: https://volcanoes.usgs.gov/vhp/notifications.html.
The Civil Defense Emergency Notification System
is a free service that allows you to receive timely notifications about emergency situations in the County of Hawai‘i. Civil Defense encourages residents and visitors to sign up so that they can be notified in case of an emergency. Standard charges for incoming calls and text messages apply. Sign up at:
