The Global Volcanism Program documents, disseminates, and archives eruption information to better understand worldwide volcanic activity. Reports are produced on daily, weekly, and multi-month timescales. Information from these reports, along with content from scientific studies and other sources, is compiled in the Volcanoes of the World database, a catalog of Holocene and Pleistocene volcanoes and their eruptions from the past 12,000 years.
