Grande Comore: Grande Comore (in Swahili: Ngazidja ) is an island in the Indian Ocean off the coast of Africa.  It is the largest island in the Comoros nation.  Most of its population is of the Comorian ethnic group.  Its population as of 2006 is about 316,600.  The island's capital is Moroni, which is also the national capital.  The island is made up of two shield volcanoes, with Mount Karthala being the country's highest point at 2361 m above sea level.  According to the 2009 revision of the constitution of 2002, it is governed by an elected Governor, as are the other islands, with the federal government being much reduced in power.

Geography of the Comoros: The Comoros archipelago consists of four main islands aligned along a northwest-southeast axis at the north end of the Mozambique Channel, between Mozambique and the island of Madagascar.  Still widely known by their French names, the islands officially have been called by their Swahili names by the Comorian government.  They are Grande Comore (Njazidja), Mohéli (Mwali), Anjouan (Nzwani), and Mayotte (Mahoré).  The islands' distance from each other—Grande Comore is some 200 kilometers from Mayotte, forty kilometers from Mohéli, and eighty kilometers from Grande Comore—along with a lack of good harbor facilities, make transportation and communication difficult.  The islands have a total land area of 2,236 square kilometers (including Mayotte), and claim territorial waters of 320 square kilometers.  Mount Karthala (2316 m) on Grande Comore is an active volcano.  From April 17 to 19, 2005, the volcano began spewing ash and gas, forcing as many as 10,000 people to flee.
