Mount Karthala or Karthola (Arabic: القرطالة Al Qirtālah) is an active volcano and the highest point of the Comoros at 2,361 m (7,746 ft) above sea level. It is the southernmost and larger of the two shield volcanoes forming Grande Comore island, the largest island in the nation of Comoros. The Karthala volcano is very active, having erupted more than 20 times since the 19th century. Frequent eruptions have shaped the volcano's 3 km by 4 km summit caldera, but the island has largely escaped broad destruction. Eruptions on April 17, 2005 and May 29, 2006 ended a period of quiet.

April 2005 eruptionEdit
The crater was clearly changed by the April 2005 eruption. A grey field of ash surrounds the crater and the caldera itself seems larger and deeper. The crater lake, which formed after Karthala's last eruption in 1991 and once dominated the caldera, is now gone completely. In its place were rough, dark grey rocks, possibly cooling lava or rubble from the collapsed crater.
May 2006 activityEdit
Flora and faunaEdit
The mountain is covered by moist evergreen forest up to about 1800 metres above sea-level. Higher up the vegetation consists of stunted trees and heathland where the giant heather Erica comorensis grows.
Many of the species found on the mountain are unique to the Comoros and four bird species are found only on the slopes of Mount Karthala: Humblot's flycatcher, Comoro white-eye, Comoro drongo and Karthala scops owl.
