Ecuador - December 1st, 2009

Cayambe (or Volcán Cayambe) is the name of a volcano located in the Cordillera Oriental, a branch of the Ecuadorian Andes. It is located in Pichincha province some 70 km (43 mi) northeast of Quito, in the upper left quadrant of this orthorectified image.

It is the third highest mountain in Ecuador. Cayambe, which has a permanent snow cap, is a Holocene compound volcano which has not erupted in historical times. At 4,690 m (15,387 ft) on its south slope is the highest point in the world crossed by the Equator and the only point on the Equator with snow cover. The volcano is located within the Cayambe-Coca Ecological Reserve.

Another volcano, Reventador, can be seen to the southeast of Cayambe, just about the center of the image. It is an active stratovolcano which lies in the eastern Andes of Ecuador. It lies in a remote area of the national park of the same name. The volcano’s main peak lies inside a U-shaped caldera which is open towards the Amazon basin to the east. Its lavas are andesitic.

Since 1541 it has erupted over 25 times, although its isolated location means that many of its eruptions have gone unreported. Its most recent eruption was in 2009, but the largest historical eruption occurred in 2002. During that eruption the plume from the volcano reached a height of 17 km and pyroclastic flows went up to 7 km from the cone.
