Komaga-take

Komaga-take

Clouds of steam pour from a new eruptive fissure cutting the summit of Japan's Komaga-take volcano on March 7, 1996. A phreatic eruption began the evening of the 5th and deposited ash on snow. The eruption originated from vents in the 1929 crater and from a 200-m-long N-S fissure. Eruptive activity, producing steam-rich ash clouds, was strong until March 7, and declined after after March 12. Komaga-take is one of the most active volcanoes on Japan's northernmost island, Hokkaido.

Komaga-take

A pyroclastic-flow deposit from the 1929 eruption of Komaga-take volcano, on the northern Japanese island of Hokkaido, overlies a brown, pre-eruption surface. The upper part of the deposit contains large blocks of pumice; layers both depleted and enriched in finer-grained material occur at the base. A geological hammer provides scale.
