Iceland's Eyjafjallajokull volcano has thrown out about 140 million cubic meters of ash over the past three days, Icelandic scientists said on Sunday.
The Institute of Earth Sciences of the University of Iceland estimated that about 100 million cubic meters of the ash rose into the air and was blown across northern Europe, canceling thousands of flights
Aeroflot on Sunday canceled 42 Monday flights but there were signs of an easing of the disruption, as Spain reopened all affected airports and Germany began to allow flights to several destinations.
Britain and Denmark, meanwhile, extended the ban through 06:00 GMT on Monday.
The Icelandic volcanologists said most of the ejected material was fine-grained airborne tephra, but 30 million cubic meters of material was deposited around the volcano vent and another 10 million in the glacial lagoon of Gigjokulslon.
They said the average magma discharge rate of 750 tons per second was 10-20 times greater than the average of the eruption in late March.
The scientists warned that the eruption and melting the surrounding glaciers could threaten serious flooding south of Iceland.
