Volcanos

Roundup of Global Volcanic Activity

Nishino-shima (Volcano Islands, Japan): The eruption on the island continues with apparently relatively steady lava effusion that feeds active flows reaching and enlarging the SE corner of the island, which has now 2.7 square kilometer of surface. Mild strombolian activity and strong degassing occurs at the main vent, where a nice cinder cone has grown. The lava mostly flows through tubes, where it is hidden, to reach the active lava delta on the SE tip of the island. A smaller part seems also to feed/inflate inland surface lava flows in an area NE of the cone.

Sinabung (Sumatra, Indonesia): A series of larger pyroclastic flows occurred yesterday, reaching lengths of up to 4.5 km and producing ash plumes that rose up to approx. 4 km. Most likely, the now relatively large dome is currently again a phase of increased destabilization and more of such dangerous pyroclastic flows (hot block and ash flows) can be expected.

Sakurajima (Kyushu, Japan): The volcano remains highly active, producing regularly 5-10 or even more vulanian-type explosions on a daily basis. A few hours ago, JMA recorded the 650th this year alone.

Zhupanovsky (Kamchatka, Russia): A small ash emission from the volcano was reported on Saturday. Based on satellite imagery, an ash plume rose to 24,000 ft (7.2 km) altitude and drifted north (Tokyo VAAC).

Asama (Honshu): Weak activity continues from the volcano's summit crater. Small ash emissions, intense degassing as well as weak incandescence from the volcano's crater have been observed during the past days.
