27 September 2016 Database updated (4.5.1). Current eruptions updated through 23 September 2016. Many corrections to volcanic feature locations. More than 2/3 of the geologic summary remarks have now been reviewed and edited in the past 3 years. Removed 19 volcanoes from the Holocene list and added 8 to the Pleistocene list since the June update.

E3 Web Application

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. The eruption and gas emission data are drawn from the Volcanoes of the World database maintained by the Global Volcanism Program.

Who We Are
