European air traffic is in chaos again as that Icelandic volcano continues to erupt and emit ash into the air.

More than a dozen airports throughout the Republic of Ireland, Northern Ireland and Scotland have been shut down, stranding tens of thousands of passengers.

Scientists have observed more powerful earthquakes about 20 kilometers beneath the volcano, which means it is still active and likely to cause more flight delays in Europe throughout summer.

European air traffic agency Eurocontrol has warned English airports at Liverpool, Bristol, Leeds and Manchester could be affected soon, as the ash drifts south-west.
