Clouds cover the flanks of the Karthala shield volcano at the S end of Grand Comore Island. A scoria cone of the northern La Grille shield volcano is on the coast in the foreground. Karthala contains a 3 x 4 km summit caldera and elongated rift zones that extend to the NNW and SE from the summit. More than twenty eruptions have been recorded at Karthala since the 19th century, but no historical eruptions are known from La Grille volcano. Copyrighted photo by Stephen and Donna O'Meara, 2002.
