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.

Who We Are

The mission of GVP is to document, understand, and disseminate information about global volcanic activity.
