A new USGS report, Science for a Risky World: A USGS Plan for Risk Research and Applications
, defines for the first time the role of USGS in risk research and applications. This includes hazard assessments, operational forecasts and warnings, vulnerability assessments, risk assessments, risk communication, decision-support systems, and post-event assessments. These activities and products are connected by the need to directly support decision makers in their efforts to better understand societal risk from hazards and to have the necessary information to make science-based, risk reduction decisions. The Risk Plan identifies the Bureau's core competencies in this arena and includes background on and specific recommendations for building institutional capacity for creating sustained partnerships, supporting professional staff, and improving product delivery.
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.
- Great Sitkin, located in the central Aleutian Islands, has been in a state of volcanic unrest since July 1, 2018. Explosive eruptions can send ash to altitudes hazardous to aviation.
- Mount Veniaminof, located on the Alaskan Peninsula, has been in a state of volcanic unrest since September 3, 2018. Seismicity is above background levels and low-level ash emissions have been observed.
- Semisopochnoi, located in the western Aleutian Islands, has been in a state of volcanic unrest since September 16, 2018. Elevated seismicity has accompanied ash emissions that may threaten aircraft.
Kīlauea Volcano on the Island of Hawai‘i is not erupting. Eruptive activity ceased in mid-August, 2018.
