Global Volcanism Program | Image GVP-10455

Cones can be seen here on the flanks of La Grille shield volcano at the N end of Grand Comore Island (also known as Ngazidja). It is located N of Karthala volcano, and the scoria cones reach up to 800 m in height. Recent lava flows, some perhaps as young as a few hundred years, have reached the sea from fissures on the lower W, N, and E flanks. Copyrighted photo by Stephen and Donna O'Meara, 2002.
