Villages cleared after volcano erupts in Iceland
A volcano erupted near a glacier in Iceland, shooting up ash and molten lava and forcing the evacuation of hundreds from nearby villages yesterday.
The eruption at the Eyjafjallajokull volcano, located near a glacier of the same name, shot ash and molten lava into the air but scientists called it mostly peaceful. It occurred just before midnight Saturday at a fissure on a slope — rather than at the volcano's summit — so scientists said there was no imminent danger that the glacier would melt and flood the area.
TV footage showed lava flowing along the fissure, and many flights were canceled due to the threat of airborne volcanic ash. After an aerial survey, scientists concluded the eruption struck near the glacier in an area that had no ice.
"This is the best possible place for an eruption," said Tumi Gudmundsson, a geologist at the University of Iceland.
Nonetheless, officials sent phone messages to 450 people between the farming village of Hvolsvollur and the fishing village of Vik, some 100 miles southeast of the capital, Reykjavik, urging them to evacuate immediately.
A state of emergency was declared although there were no immediate reports of injuries or damage. Evacuation centers were set up near the town of Hella, but many people returned to their homes later yesterday. The most immediate threat was to livestock because of the caustic gases the eruption released.
"We had to leave all our animals behind," Eli Ragnarsdottir, a 47-year-old farmer, told RUV, Iceland's national broadcaster from an evacuation center. "We got a call and a text message ... and we just went."
Scientists say it is difficult to predict what comes next. Like earthquakes, it is hard to predict the exact timing of volcanic eruptions.
"It could stop tomorrow, it could last for weeks or months. We cannot say at this stage," Gudmundsson said.
The last time there was an eruption near the 100-square-mile Eyjafjallajokull glacier was in 1821, and that was a "lazy" eruption — it lasted slowly and continuously for two years.
The latest eruption came after thousands of small earthquakes rocked the area in the past month. Scientists in Iceland have been monitoring the volcano using seismometers and global positioning instruments, but Gudmundsson noted that the beginning of Saturday's eruption was so indistinct that it initially went undetected by the instruments.
"The volcano has been inflating since the beginning of the year, both rising and swelling," said Pall Einarsson, a geophysicist at the University of Iceland's Institute of Earth Science. "Even though we were seeing increased seismic activity, it could have been months or years before we saw an eruption like this ... we couldn't say that there was an imminent risk for the area."
Einarsson and Gudmundsson said the eruption could trigger a more damaging eruption at the nearby Karla volcano, which lies under the thick Myrdalsjokull icecap and threatens massive flooding and explosive blasts if it erupts.
"One of the possible scenarios we're looking at is that this small eruption could bring about something bigger. This said, we can't speculate on when that could happen," Einarsson said.
