rust, as the lava’s volume and chemistry suggest, then it, too, may continue for months or even years....the plume is not high enough to penetrate the stratosphere and cause widespread climate perturbations. But the million tonnes of sulphur emitted so far are an unprecedented experiment in testing the effects of toxic-gas exposure, Barsotti says.
Lessons from Iceland may prove useful in understanding long-term gas exposure in other volcanic regions, such as Japan, Indonesia and Hawaii. In the early 2000s, residents around the Miyake-jima volcano in Japan were evacuated when it began erupting with roughly the same level of sulphur emissions.
In Iceland, the last similar event was a fissure eruption known as the Krafla fires that began in 1975 and lasted on and off until 1984, says Freysteinn Sigmundsson, a volcanologist at the University of Iceland and co-leader of FUTUREVOLC. If the current eruption is tapping magma deep in the c
If Brad Singer knew for sure what was happening three miles under an odd-shaped lake in the Andes, he might be less eager to spend a good part of his career investigating a volcanic field that has erupted 36 times during the last 25,000 years. As he leads a large scientific team exploring a region in the Andes called Laguna del Maule, Singer hopes the area remains quiet.
But the primary reason to expend so much effort on this area boils down to one fact: The rate of uplift is among the highest ever observed by satellite measurement for a volcano that is not actively erupting.
That uplift is almost definitely due to a large intrusion of magma — molten rock — beneath the volcanic complex. For seven years, an area larger than the city of Madison has been rising by 10 inches per year.
