Grande Comore, also known as Ngazidia, has an area of 1'148 square kilometres.

The island is made up by two volcanoes, Karthala and La Grille.

The Mount Karthala is the highest point of the Comores archipelago. It rises at 2'361 m above sea level. Karthala erupted about 20 times during the 19th century.

Moroni translated means “in the heart of the fire”, perhaps alluding to the city’s proximity to Mount Karthala.

La Grille Volcano

The volcanic crater lake, Lac Sale (Salt Lake), is situated on the northern tip of the island.

The crater grew from the beach along a fissure line. The fissure line, dotted by volcanic cones, is apparently stretching from the volcano La Grille down to the sea. The unfinished stratovolcanic structure indicates, that the volcano blew its top (unlike the other craters up in the mountains) in an enormous explosion, probably due to leaking seawater, into the active crater. The algae-rich water of the lake changes its colour twice a day; from a deep green to a shimmering blue.
