Volcanos

Roundup of Global Volcanic Activity – New Activity for the week 9 March – 15 March 2022

Asosan – Kyushu (Japan) : JMA reported that the amplitude of volcanic tremor signals at Asosan had decreased at around 1540 on 27 February and remained low. White plumes rose 600-800 m above the crater during 7-14 March. During field surveys conducted on 8 and 10 March sulfur dioxide gas emissions were 1,300 and 900 tons per day, respectively; these values were higher than those measured before the October 2021 eruption.

Bezymianny – Central Kamchatka (Russia) : According to the Tokyo VAAC an ash plume from Bezymianny was visible in satellite images at 0310 on 15 March drifting W at an altitude of 4.9 km (16,000 ft) a.s.l., signifying renewed explosive activity. By 0600 ash plumes rose to 6.1 (20,000 ft) a.s.l. and drifted S. Ash continued to be emitted through the day. The eruption intensified and at 1322 ash plumes rose to 8.2 km (27,000 ft) a.s.l. and drifted SW. Satellite images showed block-and-ash flows descended the SE flank to the base, with dense, dark brown ash plumes rising along its path. Thermal anomalies were visible at the summit and at the end of the flow. At 1750 possible ash plumes rose to 4.3 km (14,000 ft) a.s.l. and drifted W. Ash emissions continued to be visible in subsequent satellite images. Activity again intensified, and at 0110 on 16 March ash plumes rose to 11.6 km (38,000 ft) a.s.l. and drifted NE. Ash emissions continued to be detected in images through the day.

Manam – Northeast of New Guinea : The Darwin VAAC reported that on 14 March an ash plume from Manam rose to 2.4 km (8,000 ft) a.s.l. and drifted W. Ash plumes later that day and on 15 March rose to 3 km (10,000 ft) a.s.l. and drifted SW and W.
