The E-W-trending summit ridge of Eyjafjallajökull (also known as Eyjafjöll), located west of Katla volcano, is seen here from the NW with the steep-sloped Falljökull valley glacier descending at the left toward the Markafljot plain. The summit of 1666-m-high Eyjafjallajökull is truncated by a 2.5-km-wide summit caldera, which is breached to the north. Prior to 2010, the last eruption known from Eyjafjallajökull was during December 1821 to January 1823.
