Roundup of Global Volcanic Activity – New Activity for the Week 29 April 2020 – 5 May 2020
Bagana | Bougainville (Papua New Guinea) : Based on satellite and wind model data, the Darwin VAAC reported that on 1 May an ash plume from Bagana rose to 3 km (10,000 ft) a.s.l. and drifted NW and W.
Kavachi | Solomon Islands : Satellite data showed discolored water around Kavachi beginning in January 2020; the discolored plumes became more frequent, dense, and stretched for longer distances. On 25 April a satellite image showed a plume in the water that was about 15 km long but spread over an approximate area of 30 square kilometers. A small brown circle about 50,000 square meters in area indicated the presence of material over the likely vent location. An image acquired on 30 April showed a thin ribbon of discolored water extending about 50 km W of Kavachi.
Kikai | Japan : An eruption at 0609 on 29 April at Satsuma Iwo-jima, a subaerial part of Kikai’s NW caldera rim, generated a volcanic plume that rose 1 km above the crater. This was the first eruption recorded since 2 November 2019. The Alert Level remained at 2 (on a 5-level scale).
