Satellite Image, Photo of Lake Managua, Nicaragua

Lake Managua, Nicaragua January 1986 The second largest freshwater lake in Central America, Lake Managua can be seen in this west-southwest-looking view. Located in a rift valley, Lake Managua is 34 miles (56 km) long and 15 miles (24 km) wide. Lake Nicaragua is drained by the San Juan River, which flows east-southeast through a rift valley and empties into the Caribbean Sea. Also visible in this view are a number of volcanoes and volcano craters. This line of young volcanoes lie about 47 miles (75 km) inland from the Pacific Ocean (upper left) and are just to the west of a large coastal fracture or structural rift. The soils around the volcanoes are very fertile, and numerous agricultural field patterns are discernible scattered throughout the image. Just to the left of the bottom center of the image is the capital city of Managua, the industrial and commercial center of the country. The climate of the city is normally very hot and sultry. The city has been prone to many destructive earthquakes during its history, the last one occurring December 23, 1972 when Managua was almost completely destroyed and more than 10000 lives were lost.

Satellite Image, Photo of Lakes Managua & Nicaragua, Nicaragua

Lake Managua, Nicaragua January 1997 The dark-looking water of Lake Managua (left middle) and the northwest end of Lake Nicaragua (right middle) stand out in marked contrast with the volcanic landscape of western Nicaragua in this color infrared image. Most of the land between the two lakes is used for agriculture (note the cultivated field patterns). There is a light colored sediment plume in the water along the east shore of Lake Managua. The smaller dark features that are aligned northwest to southeast display the location of four craters/calderas that have been filled with water. These water-filled structures help to identify the active volcanic belt that borders and parallels the west coast of Central America. The capital of Nicaragua, Managua, is the highly reflective (lighter in color) area south of Lake Managua. Masaya Volcano, a composite twin volcano with multiple summit craters and a caldera lake along the east side of the volcano, is discernible southeast of the city of Managua (slightly below the center of the image). Notice how the color infrared picture (green vegetation is portrayed as reddish colors) helps to document the deeply eroded western flanks of the low mountains in the lower third of the picture.

Nicaraguan Volcanoes

Smoke can be seen streaming from the vicinity of Nicaraguas Masaya volcano in this SeaWiFS image. Another smoke-like feature can be seen further north (perhaps originating at the San Cristobal volcano complex). The smoke plumes are set against the highly productive waters in the upwelling region known as the Costa Rica Dome.

Volcano San Cristobal

There appears to be a lot of haze blowing southward from Central America in this SeaWiFS image. The plume near the right side of the image appears to originate at the top of the volcano, San Cristobal, in Nicaragua.

Nicaraguan Smoke Plumes

There still appears to be a bit of smoke coming from the volcano San Cristobal in this SeaWiFS image. A considerably more prominent smoke plume appears to originate at Volcan Masaya between Lake Managua and Lake Nicaragua.

San Cristobal Volcano

On December 16, 2002, the San Cristobal volcano in Nicaragua spewed out a plume of smoke and ash visible from space. The gray plume of smoke can be seen in this image captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite. San Cristobal is an active stratovolcano in the San Cristobal complex on the west coast of Nicaragua. The volcano periodically spits out ash and smoke over the Central American jungles. The red dots at the bottom of the image are brush fires in southern Nicaragua.
