REYKJAVIK, April 18 (Reuters) - Powerful tremors from an Icelandic volcano that has been a menace for thousands of travellers worldwide rocked the countryside on Sunday as eruptions hurled a steady stream of ash into the sky.
Ash from the volcano drifted southeast towards Europe, sparing the capital Reykjavik and other more populated centres but forcing farmers and their livestock indoors as a blanket of ash fell on the surrounding areas.
Iceland's Meterological Office said tremors from the volcano had grown more intense and had increased from a day ago, but that the column of steam and ash rising from the volcano had eased back to 4-5 km (2.5-3 miles) from as high as 11 km when it started erupting earlier this week.
"We are seeing mixed signals. There are some hints that the eruption will be decreasing, and others that show it is not decreasing," Einar Kjartansson, a geophysicist at the Meteorological Office, told Reuters.http://live.reuters.com/Event/Volcanic_ash_cloud_developments
