Image Collection | Types and Features | Stratovolcanoes

There are 5,971 volcano images available on the GVP website, including 4,243 in these new galleries with updated captions and keywords, and at a larger size.

Stratovolcanoes, also called composite volcanoes, erupt a variety of magma types spanning basalt, andesite, dacite, and rhyolite to produce a wide range of eruption styles. These large complex volcanoes form over tens to hundreds of thousands of years from accumulating lava flows, lava domes, and explosive deposits, and may have multiple eruption centers or vents. Hazards include lava flows, pyroclastic flows (also called pyroclastic density currents), dome collapse, structural failure (small landslides and large flank collapse), ballistic ejecta, lahars (also called debris flows), volcanic gas, volcanic lightning, and ashfall. Over the course their lifespans, dormant periods may last tens of thousands of years.
