    • Washington Volcanic Ash Advisory Center Volcanic Ash Advisories and Volcanic Ash Graphics from 2007 to 2024

    Metadata Updated: June 1, 2025

    The Washington Volcanic Ash Advisory Center is a 365/24/7 operational group that is part of the NOAA/National Environmental Satellite, Data, and Information Service (NESDIS)/Office of Satellite and Product Operations (OSPO) Satellite Analysis Branch. It provides volcanic activity monitoring along with creating and disseminating Volcanic Ash Advisories (VAA) and Volcanic Ash Graphics (VAG). The center's area of responsibility is the US including Hawaii, the Caribbean, Central America, northern South America, parts of the Pacific Ocean including the Marianas Islands. Data input for VAA and VAG include satellite imagery, model data, reports from State Volcano Observatories (SVO), Meteorological Watch Offices (MWO), many air traffic groups and others. Main users of VAA and VAG products include the aviation community including international and domestic airlines, air traffic control groups, the private sector, and scientific groups like the US Geological Survey (USGS).

    This collection of volcanic ash advisories and graphics is organized by each calendar year being contained within its own accession. Specifically:
