Air travel over Essex could be disrupted again after earthquakes were felt near Iceland's largest volcano range.
Yesterday the country's Met Office raised the risk level to the aviation industry to orange after tremors beneath the Bardarbunga volcano, warning "heightened or escalating unrest with increased potential of eruption".
"Seismic activity" has been recorded over the last week, with magma movement noticed only 10km beneath the surface.
In 2010 an eruption of the Eyjafjallajokull volcano, which is in a different system to Bardabunga, brought much of Europe's air travel to a standstill for nearly a week, affecting more than 10 million people.
If Bardarbunga erupts it could cause a flood and create an ash cloud similar to 2010, Iceland's Met Office has warned.
There is no confirmation on when any eruption could occur.
