Aerial footage shot in September shows massive lava flows cascading down the side of the mountain. A look inside the crater of the volcano shows lava being spewed hundreds of feet in the air.
Icelandic authorities first became aware of this latest eruption in late August. Airspace around the volcano was closed, but officials said commercial air traffic was not affected.
The eruption first raised concerns because of one in 2010, when Iceland's Eyjafjallajoekull volcano erupted and sparked a week of international aviation chaos. Thousands of flights were cancelled when Europe's air space was closed for five days, fearing that volcanic ash could harm jet engines.
