Volcanic eruptions in Iceland are capable of affecting air traffic across Europe, as the Eyjafjallajokull volcano showed by grounding flights for a week in 2010.
Katla has had numerous earthquakes since Oktober 2010. This swarm of quakes have been nearer the surface and this indicates that something is happening with Magma moving towards the surface.
Now, recent tremors around the much larger Katla volcano indicate that it may be nearing eruption as well. Experts are concerned that such an event could bring global travel disruptions and flooding from melted glaciers.
Last December, multiple strange bright lights were spotted in area around Katla Volcano and recorded on the Katla Webcam.
The UFOs are too bright in this distance being a snowmobile as well as the moves of these objects.
