A strong volcano in Iceland is about to spray

A more frightening volcano of Eyjafjallajakull - which caused European air turbulence last month - is preparing to erupt.

British scientists have just reported this news and they are concerned that movements beneath the volcano under the Eyjafjallajokull glacier may awaken Katla - a more dangerous volcano nearby. If Katla awakens, world aviation may face the worst scenario ever.

Katla's ability to erupt in the near future is quite large , AFP quoted a report from the University of London, UK, released today.

If Katla woke up, it would erupt about 10 times stronger than the Eyjafjallajokull volcano and its ashes also flew higher. Experts are concerned that the European sky will be closed much longer than the April ban.

Volcanic eruption in the Eyjafjallajakull glacier begins on April 14. Its ash fly across Europe and paralyzes airline activity on the continent for days. This is the longest and largest flight ban in Europe since World War II. More than 100,000 flights were canceled and 8 million passengers were stranded at airports.
