The erupting volcano in Iceland sent new tremors on Monday, but the ash plume which has caused air traffic chaos across Europe has dropped to a height of about 2 km (1.2 miles), the Meteorological Office said.

Visibility near the Eyjafjallajokull glacier was almost nil as falling ash saturated the air and covered agricultural fields with a thin layer of dust which could be dangerous to animals if eaten, local media quoted the police as saying.

There was a risk, however, that molten rock could create new pathways for water to run into the crater, causing more explosions and a higher level of ash production.

The ash plume, which has cost airlines millions of dollars per day in lost revenue, had descended to a lower altitude as strong winds continued to push the cloud southward.

The ash plume is very low. It’s not much higher than 2 kilometers. The column of ash rising from the volcano was as high as 11 km when it started erupting earlier last week.

Air traffic over Europe remained severely disrupted on Monday.

Europe’s air travel chaos deepened on Saturday as a huge cloud of volcanic ash spread southeast across the continent, halting more than three in four flights and stranding tens of thousands of passengers worldwide.

European aviation agency Eurocontrol said no landings or takeoffs were possible for civilian aircraft in most of northern and central Europe because of the ash spewed out by the Icelandic volcano, which was still erupting.

Many countries closed airspace until Sunday or Monday and weather experts forecast the cloud would not move far. They said the plume of ash could even become more concentrated on Tuesday and Wednesday, posing a greater threat to air travel.

The plume that floated through the upper atmosphere, where it could wreak havoc on jet engines and airframes, is costing airlines more than $200 million a day.

A plume of ash has spread across northern Europe from a volcano beneath the Eyjafjallajoekull glacier in southern Iceland. Icelandic media report that the eruption is continuing, but there have been no earth tremors since Thursday evening.

Volcanic ash has fallen in parts of eastern Iceland and there are fears that ash could spread to Reykjavik if the wind direction changes.

There are fears of an even bigger eruption if the vulcanism sets off the nearby Katla Volcano, which is also covered in ice.

Air traffic has been severely disrupted across northern Europe by the volcanic ash, seen stretching from Iceland (upper left corner) to Western Europe (right) in the main image.

Airspace has been closed or flights cancelled in countries including the UK, the Republic of Ireland, Denmark, Norway, Sweden, Finland and France.

All flights in and out of the UK and several other European countries have been suspended as ash from a volcanic eruption in Iceland moves south. Two of the detail images show the ash veiling the skies over Western Europe, while another provides a map of the spreading of the ash.

In addition, the eruption has caused parts of the glacier to break up and melt, causing flooding in areas around the erupting volcano and prompting the second evacuation of local people in 48 hours. The level of the glacial Markarfljot river – swollen with ice and mud – has also risen. The flooding has cut off the coast road from the area to the capital Reykjavik and threatens isolated farms.
