The summit ridge of Eyjafjallajökull is seen here in 1992 from the NW with a steep-sloped valley glacier descending at the left toward the Markafljot plain. The summit is truncated by a 2.5-km-wide, ice-filled caldera breached to the north (towards bottom left). Prior to 2010, the last eruption known from Eyjafjallajökull was during December 1821 to January 1823.
