(Reuters) — Iceland’s Bardarbunga volcano poured out more lava on Wednesday, but no ash was emerging from the eruption, authorities said.
The ash warning for aviation stood at orange, the second-highest level on a five-color scale indicating a risk of ash that could hinder air traffic, after a brief rise to the top level of red on Sunday when lava fountains rose 55 yards high.
In 2010, an ash cloud from the Eyjafjallajokull volcano, in a different region of Iceland, closed much of Europe’s air space for six days after an eruption under the icecap.
“The eruption is still going on at the same pace as before,” said Einar Heinarsson, a spokesman at Iceland’s department of civil protection. “It has been continuous.”
He said lava emerging from a fissure near the volcano had covered an area of about 2.5 square miles and was moving northeast towards a river where geoscientists expected some minor gas explosions.
Seismic activity in the area had not diminished and remained stable, he added.
If the fissure that the lava is flowing from closes, there is a possibility that new ones might open up, possibly closer to the Vatnajokull glacier, said Kristin Jonsdottir, a geophysicist at the Meteorological Office.
“Therefore, an eruption at Bardarbunga, beneath the glacier, cannot be ruled out,” she said.
