No recent earthquakesIntroduction
La Grille shield volcano at the northern end of Grand Comore Island (also known as Ngazidja) lacks a summit caldera like its larger and more well-known neighbor to the south, Karthala volcano. The basaltic La Grille volcano also contrasts with Karthala in its abundance of pyroclastic cones up to 800 m in height. The cones were erupted along fissures paralleling the summit ridge, which has an irregular profile and is elongated in a N-S direction, 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 western, northern, and eastern flanks.---
