Stratovolcano • Also known as composite, stratovolcanoes are conical and shape. • They are built up by many layers (strata) of hardened lava, tephra, pumice, and volcanic ash. • Known for periodic explosive and quiet eruptions. Click Here to Go Back
Stratovolcano Cntd. • Lava that flows from stratovolcanoes typically cools and hardens before spreading far due to high viscosity. • Fun Facts: Mount Vesuvius, perhaps the most well known volcano, is a stratovolcano. Mount Fuji, another well known stratovolcano, last erupted in 1707-1708. Click Here to Go Back
Shield • Usually built entirely of fluid lava flows. • Names for their large size and low profile, resembling a shield lying on the ground. • Lava flows more quickly due to low viscosity. Click Here to Go Back
Shield Cntd. • Fun Facts: • The Hawaiian Islands are composed of linear chains of shield volcanoes, including the largest active volcano on the planet, Mauna Loa. • Olympus Mons on Mars, is also a shield volcano. Click Here to Go Back
Spatter • Formed of molten lava ejected from a vent, with a viscosity somewhat like taffy. • They are relatively explosive, but fall near the crater. • The explosive bits that come out splash over the side and due to them being partly liquid rock, they form mounds called spatters.

Spatter Cntd. • Fun Facts: • A famous spatter volcano has the wonderful name, PuʻuʻŌʻō. • This volcano has been fairly active in recent years. Click Here to Go Back
Cinder • Cinder Volcanoes, are also known as volcanic cones. • They are built up by ejecta from a volcanic vent piling up around the vent in the shape of a cone with a central crater. • Cinder cones are commonly found on the flanks of shield volcanoes. Click Here to Go Back
Cinder Cntd. • These volcanoes are usually very small, but very steep. • Fun Facts: • There are around 100 identified cinder cones on the flanks of Mauna Kea. Click Here to Go Back
