Flight discovers lower dome temperatures

14/10/2016 Nick

After trying to fly for several weeks, finally we managed to have the right conditions and 5 willing participants. After having measured high temperatures earlier in the month (highest temps. yet measured for this volcano) the temperatures were much lower with a maximum of only 320° C. This reflects the reduction in the effusion rate. The eruption is shifting from passive magma emplacement to the more common small Vulcanian eruptions occurring at least once per hour.
