Three Central American countries—El Salvador, Honduras, and Nicaragua—have coastline along the Gulf of Fonseca, which opens into the Pacific Ocean. The southern boundary of the Gulf is a peninsula formed by the Cosigüina Volcano. Cosigüina is a stratovolcano, which is a cone-shaped volcano formed by alternating layers of solidified lava and volcanic rocks produced by explosive eruptions.

Located approximately 50 kilometers northeast of Tehran, Mt. Damavand is an impressive stratovolcano that reaches 5,670 meters (18,598 feet) in elevation. Part of the Alborz Mountain Range that borders the Caspian Sea to the north, Damavand is a young volcano that has formed mostly during the Holocene Epoch (over approximately the last 10,000 years). The western flank of the volcano includes solidified lava flows with flow levees—“walls” formed as the side edges of flowing lava cooled rapidly, forming a chute that channeled the hotter, interior lava. Two such flows with well-defined levees are highlighted by snow on the mountainside.
