地質学的概要
La Grille is a basaltic shield volcano at the N end of Grand Comore Island (Ngazidja). Unlike the larger Karthala volcano to the S, it lacks a summit caldera but has an abundance of pyroclastic cones. The cones were erupted along fissures paralleling the irregular N-S summit ridge and from radial fissures that reach as far as the coast. 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.
