BARREN ISLAND VOLCANISM DURING 12-13TH JANUARY, 2006

To monitor the ongoing volcanism of Barren Island Volcano a team of Geological Survey of India comprising Dr. M.M. Mukherjee, Dy. Director General, Op: WB-SK-AN, Dr. P.C. Bandopadhyay, Geologist(Sr), Op: WB-SK-AN, Dr. Tapan Pal, Geologist(Sr), Sri N.R. Mohapatra, Geologist(Sr), Op: WB-SK-AN and Sri Prasun Ghosh, Geologist(Jr), Op: WB-SK-AN approached Barren Island by Indian Coast Guard Ship, C.S. GANGA DEVI during 12-13th January, 2006. The party could reach very close to the Barren Island (up to 0.8 km) and studied the nature of eruption from shipboard during daytime and after sunset. The eruption resembled fire works of different colours over the crater and on the slope of the volcanic cone. Dense cluster of incandescent tephra particles of various sizes were ejecting out from the crater mouth forcefully with ballistic trajectories. Apart from eruption form the main crater, glow of fire from the northern flank of the volcanic cone and thin layers of red hot materials on western slope were observed. The volcanic activity compared to its early stage of eruption during May-June, 2005 had subsided to a grey smoke and minor amount of ash were emitting out from the same crater, producing very thin (about 20m to 30 m high) eruption column. Lava flow sensustricto was not noticed.
