GEOLOGY

Detailed explanation-1: -The eruptions of most cinder cones are usually mildly to moderately explosive (Strombolian to Vulcanian), but rarely can have Sub-Plinian activity. Their usually low explosivity is due to the low viscosity and low volatile content of magma.

Detailed explanation-2: -Cinder cones develop from explosive eruptions of mafic (heavy, dark ferromagnesian) and intermediate lavas and are often found along the flanks of shield volcanoes. The outside of the cone is often inclined at about 30°, the angle of repose (the slope at which the loose cinder can stand in equilibrium).

Detailed explanation-3: -Cinder conesCinder cones, sometimes called scoria cones or pyroclastic cones, are the most common types of volcanic cones. They form after violent eruptions blow lava fragments into the air, which then solidify and fall as cinders around the volcanic vent.

Detailed explanation-4: -The Vulcanian type, named for Vulcano Island near Stromboli, generally involves moderate explosions of gas laden with volcanic ash. This mixture forms dark, turbulent eruption clouds that rapidly ascend and expand in convoluted shapes.

Detailed explanation-5: -Strombolian eruptions are short lived explosive eruptions that shoot very thick and pasty lava into the air along with bursts of steam and gas. Strombolian eruptions usually produce little or no lava. Because of this the cones that are produced by this type of eruption is a very steep sided cone called a cinder cone.
