"We returned to the fissure early this morning and saw considerable volcanic activity at around 7 AM," says Dr. Hoskuldsson. He and other scientists spent the night at a mountain hut nearby, after an evacuation was ordered yesterday when volcanic tremor was detected in the area, leading to fears that a subglacial eruption was imminent. "The main craters are now very active and the lava fountains from them rise up to 120 - 130 meter height," he says.A commenter at Ice Age Now said,
At the moment this eruption alone is pouring out more SO2 than the whole world’s human production.
I saw some Iceland Met office figures a day or so ago. 80%+ of the emissions are H20. 15% CO2 and 5% SO2 + assorted. If the fluorine count increases this will be a real worry.
There are some reports that the Laki fissure eruptions of the 18th century had lava fountains over a kilometer high.
I'm impressed that one volcano gives off more sulfur dioxide than the entire human race. So far, this is considered a small eruption. But remember: your SUV, or the exhaust from your lawnmower, or from your outboard motor, are a threat to the planet.
