Types of Eruptions
Hawaiian Eruption
- Fluid basaltic lava is thrown into the air in jets from a vent or line of vents at the summit or on the flank of a volcano.

Strombolian Eruption
- Distinct bursts of fluid lava from the mouth of a magma- filled summit conduit.

Vulcanian Eruption
- Short, violent, relatively small explosion of viscous magma.

The most common type of volcanic eruptions occur when magma (lava) is released from a volcanic vent.

Types of Volcanoes
Cinder Cones

- Simplest type of volcano.
- Built from particles and blobs of congealed lava ejected form a single vent.

Composite Volcano
- Some of the Earth's grandest mountains are composite volcanoes
- They are typically step- sided, symmetrical cones of large dimension built of alternating layers of lava flows, volcanic ash, cinders, blocks, and bombs and may rise as much as 8,000 feet above their bases

Shield Volcano
- Built entirely of fluid lava flows

Lava Domes
- Formed by relatively small, bulbous masses of lava too viscous to flow any great distance; consequently, on extrusion, the lava piles over and around its vent.
