Sakurajima volcano (Japan): activity summary 4-10 Sep 2013
Wednesday Sep 11, 2013 10:05 AM | BY: T
JMA reported that 15 explosions from Sakura-jima's Showa Crater ejected tephra as far as 1,300 m during 2-6 September. Incandescence from the crater was visible some nights. An explosion at 1100 on 4 September generated an ash plume that rose 2.8 km and drifted S, causing ashfall in areas downwind including Arimuracho (4 km SSE). Tephra 4 cm in diameter was confirmed in an area 3 km S, and tephra 1 cm in diameter was reported 10 km SSE.
Based on information from JMA, the Tokyo VAAC reported that during 4-10 September explosions generated plumes that rose to altitudes of 2.4-4.3 km (8,000-14,000 ft) a.s.l., and most days drifted N, NE, E, S, and SW. On 6 and 8 September pilots observed ash plumes that rose to altitudes of 3-4.6 km (15,000 ft) a.s.l.; plumes drifted NE on 8 September.

On 21 August, the volcano had at least 8 (!) vulcanian-type explosions with ash plumes rising up to 15,000 ft (4,5 km) altitude that often drifted over the bay and Kagoshima city, causing ash fall there. Some of the explosions can be seen on the following time-lapse video. The volcano has been in an elevated state of activity during the past weeks. A significant hot spot is visible on MODIS data, suggesting that magma levels are high in the crater and the presence of significant amounts of still hot fresh deposits on the flanks. ... [more]
