Frequently Asked Questions (more questions are available) How many active volcanoes are there?| 40-50 continuing eruptions at any given time. Has volcanic activity been increasing?| What was erupting in the year...?| Range of 56-88 total eruptions per year since 1994. What volcanoes have had the longest eruptions?| 91 eruptions 5 years or longer. What volcanoes have the most people living nearby?| 10 have 1 million people within 5 km. What volcanoes are the most noteworthy?| 185 volcanoes with significant activity or impacts. 17 March 2021 Database updated (4.9.4). Current eruptions updated through 12 March 2021. General updates to volcano data. 1 February 2021 Database updated (4.9.3). Current eruptions updated through 28 January 2021. General updates to volcano data. 15 December 2020 Database updated (4.9.2). Current eruptions updated through 10 December 2020. General updates to volcano data. Style and organizational changes. 2 November 2020 Launched new 20th Anniversary of the Smithsonian / USGS Weekly Volcanic Activity Report (WVAR) page and updated the style of the main WVAR page. The Eruptions, Earthquakes, Emissions web application (or E3 ) is a time-lapse animation of volcanic eruptions and earthquakes since 1960. It also shows volcanic gas emissions (sulfur dioxide, SO2) since 1978 the first year satellites were available to provide global monitoring of SO2. Who We Are The mission of GVP is to document, understand, and disseminate information about global volcanic activity.

The Global Volcanism Program (GVP) seeks better understanding of all volcanoes through documenting their eruptions--small as well as large--during the past 10,000 years. The range of volcanic behavior is great enough, and volcano lifetimes are long enough, that we must integrate observations of contemporary activity with historical and geological records of the recent past in order to prepare wisely for the future. The contemporary focus of the GVP is evident in the central role we play in the rapid dissemination of on-going eruption reports from local observers through our monthly Bulletin of the Global Volcanism Network. Our retrospective effort to document Earth's volcanic eruptions of the last 10,000 years has led to development of comprehensive databases and an archive of relevant maps, photos, and documents. Through these two complementary approaches we attempt to provide a context in which any individual volcano's benefits and dangers can be usefully assessed.
