ディアブロティン山

Morne Diablotins, in northern Dominica, is the largest and highest on the island. A complex of at least five coalescing lava domes forms the broad summit, and other domes are found to the SE. Pyroclastic-flow deposits emplaced ~22,000-40,000 years ago, known as the Grand Savanne Ignimbrite, extend in five radial lobes around the volcano as far as the coast. Pre-Columbian block-and-ash flow aprons on the NW flank are relatively unmodified by erosion. No recent eruptions are known, although numerous hot springs, both onshore and submarine, are found near Glanvillia, on the NW flank. Severe earthquake swarms in 1841 and 1893 originated either from Morne Diablotins or Morne aux Diables to the N.
