JMA reported that in 3-7 March six explosions from Showa Crater at Aira Caldera’s Sakurajima volcano ejected tephra as far as 1,300 m. The Tokyo VAAC reported explosions throughout 5-11 March. Plumes rose to altitudes of 1.2-3 km (4,000-10,000 ft) a.s.l. and drifted NE, E, SE, and S.
One of the explosions, recorded at 2010 on 28 November, produced an eruption plume that rose three.three km. JMA reported that in February there were 34 explosions and 19 non-explosive eruptive events detected by the Minamidake Crater (at Aira Caldera’s Sakurajima volcano) seismic community. Ash plumes rose as excessive as 2.4 km above the crater rim and materials was ejected 600-1,100 m away from the crater. The sulfur dioxide emission rate was elevated at 1,900 tons/day on 20 February.
On four and 5 June, intermittent eruptions at Sakura-jima, from an higher E-flank vent, near or inside the 1946 vent, produced ash clouds that reached unknown heights. This was the first reported Sakura-jima eruption from a vent outside the summit crater in fifty eight years. The 1946 vent was the source of major lava flows that reached the E and S coasts of the previous island. The JMA reported that explosions from Showa crater on 2 October ejected incandescent tephra 800 m away from the rim. On 3 October, Minami-dake crater exploded violently, producing an ash plume that rose three km above the crater.
JMA reported that during March two explosions from Showa Crater at Aira Caldera’s Sakurajima volcano ejected tephra so far as 1,300 m. Volcanologists conducting a area survey on 10 March noted that sulfur dioxide emissions were one hundred ninety tons per day, lower than the 1,900 tons per day they measured on four March. JMA reported that during february 7 2008 cartoon network 7-11 April two explosions from Showa Crater at Aira Caldera’s Sakurajima volcano ejected tephra as far as 800 m. Incandescence from the crater was detected in the course of the night time of 10 April. The Tokyo VAAC reported that on 10 and 12 April plumes rose to an altitude of two.4 km a.s.l. Plumes drifted SE on 10 April.
The most amplitude of explosion seismic indicators at JMA statement point A (4.6 km WNW of the active crater) was 17 µm for the 0513 explosion on 14 January. A Japan Meteorological Agency volcanic advisory on 19 May acknowledged that a swarm of volcanic earthquakes began at about 1700; in the following 4 hours, approximately 220 earthquakes have been recorded. Daily earthquake counts had been 334 on 19 May and 41 on 20 May.
