Iceland volcano sends new tremors, lower ash cloud

STOCKHOLM (Reuters) - The erupting volcano in Iceland sent further strong tremors throughout the surrounding area on Monday but the ash plume which has caused air traffic chaos has descended to an altitude of about 2 km (1.2 miles), the Meteorological Office said.

"The ash plume is very low. It's not much higher than 2 kilometers," Hjorleifur Sveinbjornsson, a geologist at the Meteorological Office, told Reuters.

The column of ash from the volcano rose to an altitude of 11 km when it began erupting earlier last week.

"Strong winds from the north are blowing the ash south. We have seen strong volcanic tremors, so there must have been some changes on the surface of the volcano. Possibly there is some lava coming out," he said.
