Stratovolcanoes are . 5), such as Kilauea, form by effusive eruptions of fluid lava. Stratovolcanoes show inter-layering of lava flows and pyroclastic material, which is why they are sometimes called composite volcanoes. Its most recent eruption cycle ended about 1,000 years ago, and it last erupts every half million years. These volcanoes have steep slopes that are the result of many layers (thus, they have a stratified appearance) of volcanic material and lava flows having built up over past eruptions. That being said, with this much ash being deposited, there is likely a plinian component to the eruption, making it likely to have been a larger eruption than many of the recent events at Galeras, the last ending in January 2008 (VEI ~2). The type of eruption, whether explosive or nonexplosive, also affects the overall shape.

Crater-lake calderas result from the collapse of a stratovolcano after a Plinian eruption, the most explosive type of volcanic eruption. • Scientific Method Step 4- Test your predictions: We will conduct two experiments to better understand the controls on volcanic eruptions. Stratovolcanoes have a steep profile at their upper ends because the lava cools and hardens quickly resulting in many layers building up over time, creating the taller, steep shape. These explosive eruptions have been clustered into 6-12 eruptive periods. If eruptions of cinder and lava flows happen repeatedly from the same vent, the overlapping layers can form a composite volcano (stratovolcano). The last eruption of this stratovolcano occurred in March 1944.
