Intermittently active, the Santa Maria Volcano released a plume in mid-January 2007.
Published Feb 4, 2007Plumes streaming from this mountain in Guatemala are usually related to volcanic activity. But in March 2018, a wildfire burned on its slopes.
Published Mar 23, 2018The eruption of Santa Maria volcano in 1902 was one of the largest eruptions of the 20th century, forming a large crater on the mountain’s southwest flank. Since 1922, a lava-dome complex, Santiaguito, has been forming in the 1902 crater. Growth of the dome has produced pyroclastic flows as recently as the 2001—they can be identified in this image. The volcano is considered dangerous because of the possibility of a dome collapse such as one that occurred in 1929, which killed about 5000 people. A second hazard results from the flow of volcanic debris into rivers south of Santiaguito, which can lead tocatastrophic flooding and mud flows.

Published Apr 6, 2009Three 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.
