There are three main types of volcanoes • Shield Volcano • Stratovolcano (also called composite volcano) • Cinder cone volcano • Lava Domes are also worth mentioning
Low, rounded profiles • Slopes from 2-10 degrees • Composed of mafic, low-viscosity flows • Basalt lava flows • Kilauea volcano and Mauna Loa on Hawaii Shield Volcanoes
Pyroclastic layers and lava flows of intermediate composition • Lahars: volcanic mudflow, rain or eruption • Steep-sided near top • Typical in continental and island volcanic arcs at convergent boundaries • Violent and dangerous eruptions Stratovolcano
Small and steep-sided • Pyroclastic materials accumulate around vent • Slope angles to 33 degrees • Often form on flanks of larger volcanoes, or in calderas: final stage of basaltic volcanism Cinder Cone
Viscous felsic or intermediate magmas • Slow eruptions caused by great pressure below • Violent, destructive eruptions • Nueeardente: fast-moving cloud of pyroclastic materials and gases Lava Domes
