Soputan, Sulawesi, Indonesia

CVGHM reported that the eruption of Soputan during 6-7 June caused part of the crater wall to collapse creating an opening to the W, and the diameter of the crater to increase. Ash plumes generated on 6 June drifted NW, W, SW, and as far as 60 km S. Ash deposits were about 4 cm thick in an area 5 km NW. A nearby coconut plantation reported damage to trees. During 7-18 June, seismicity decreased and white plumes at altitudes at or less than 1.8 km (5,900 ft) a.s.l. were spotted when clouds did not inhibit observations. On 18 June, the Alert Level was decreased to 2 (on a scale of 1-4).
