A volcano, 1,491 m (4,891 ft) high, of southwest Iceland. In medieval Icelandic folklore, Hekla was believed to be one of the gateways to purgatory. It is Iceland's most active volcano, having had more than a dozen major eruptions since the 1100s.
On the west of Mount Hekla this plain connects by a regular slope directly with the tableland, to the great injury of its inhabited districts, which are thus exposed to the clouds of pumice dust and driftsand that cover large areas of the interior.
The best-known volcano is Hekla (5108 ft.), which was in eruption eighteen times within the historic period down to 1845.
