WebA flank eruption is a volcanic eruption which occurs on the flanks of a volcano, instead of at its summit. Such eruptions occur when the conduit connecting the summit to the magma chamber below is blocked, forcing the magma to move laterally. Overview. At some volcanoes, flank eruptions are common, and occur along clearly defined rift zones. WebCinder cones are commonly found on the flanks of shield volcanoes, stratovolcanoes, and calderas. For example, geologists have identified nearly 100 cinder cones on the flanks of Mauna Kea, a shield volcano located on the Island of Hawai`i (these cones are also referred to as scoria cones and cinder and spatter cones).

Heavy debris falls rapidly from the sky and flows down the flanks of the volcano, mostly as pumice. In fact, this type of flow is sometimes known as a “pumice flow.” The higher the volcanic debris is thrust into the air, the further it will fall by force of gravity, gaining momentum along the way. greco roman myths

It is composed of fine pieces of glass and rock. Magma is a mix of liquid rocks and gases at a very high temperature (800 to 1200°C) in the mantle. Due to Archimedes’ buoyancy, this liquid is less dense than its surrounding solid environment and is therefore uprising and fractures the upper rocks.
