Flank Craters

1. Such features are known as flank vents, flank cones or flank craters.

Active

1. Summit eruptions dominated from 3,000 to 2,000 years ago, after which flank vents were active.

Sw Flank

1. Extensive Holocene lava fields on the western flank were primarily fed by summit vents; those on the SW flank originated from flank vents.

Northern Coast

1. Flank vents occur on the south side of Doro Mantoi and near the northern coast.

Stratovolcanoes

1. Cinder and tephra cones usually occur around summit vents and flank vents of stratovolcanoes.

Scoria Cones

1. All of these eruptions were on flank vents and produced lava flows and scoria cones.

Summit

1. Most stratovolcanoes are complex structures formed by multiple eruptions from summit and flank vents.
2. Adams was active throughout the Holocene, producing two dozen minor explosive eruptions from summit and flank vents.
3. In 1939 explosive and effusive activity occurred from summit and flank vents, and water spouts were reported 1.6 km SE of the island.

Cinder Cones

1. Cinder cones may form as flank vents on larger volcanoes, or occur on their own.

Central Crater

1. Many contemporary active volcanoes rise as young parasitic cones from flank vents or at a central crater.

Flank Vents

1. During historical time, moderate explosive and effusive eruptions have occurred from both summit and flank vents.
2. Basaltic lava flows from both summit and flank vents have reached the caldera floor and the shores of Lake Batur in historical time.
3. Its historical activity has consisted of moderate explosive and effusive eruptions from both summit and flank vents.
