Volcanos

Roundup of Global Volcanic Activity

Alaid (Northern Kuriles): The new eruptive phase that started in late February continues. An intense thermal anomaly has been detected from the volcano's summit area on satellite imagery and weak ash emissions extending approx. 60 km NW from the island were observed yesterday and this morning.

Suwanose-jima (Ryukyu Islands): The latest eruptive phase of the volcano continues, but seems to be less vigorous. An explosion that generated a small ash plume was reported by Tokyo VAAC yesterday.

Sinabung (Sumatra, Indonesia): Activity of the volcano continues essentially unchanged with very slow lava extrusion and intermittent small to moderate explosions at the lava dome. These occur at irregular intervals almost daily, generating ash plumes that rise 1-3 km: last evening, an explosion produced a plume that rose approx. 2500 m, local observers reported. This morning, an ash plume to 9,000 ft (2.7 km) altitude was reported by Darwin VAAC.

Copahue (Chile/Argentina): Ash emissions from the volcano (which had been less vigorous and more intermittent over the previous days) have increased this morning and become continuous. Buenos Aires VAAC reported a plume at approx. 12,000 ft (3.6 km) altitude extending 35 km east from the volcano.
