Iceland volcano

Summary

19 April 2010

Scientists say the cloud of ash from the eruption¹ of the Icelandic volcano, which has caused chaos² to air travellers across Europe, appears to be changing.

Report

Conditions on the ground immediately downstream of the volcano are extremely difficult. A lot of ash is falling. Approximately ten centimetres of volcanic³ dust has settled on the ground.

Visibility is down to just a few metres and the authorities are using specially⁴ modified vehicles, armoured personnel carriers to visit and check on people who remain in the area.

But the top of the ash cloud reaching into the sky has lowered. It is no longer registering on weather radar⁵ and scientists estimate its maximum height is now around three to four thousand metres.

Much less ash is now being released into the atmosphere compared to the beginning of this eruption and scientists say they believe the volcanic activity may now be entering a different phase.
