Hekla is an active volcano in southwestern …

Years: 1104 - 1104

Hekla is an active volcano in southwestern Iceland, located in an agricultural area seventy miles (one hundred and thirteen kilometers) east of Reykjavik.

Known as Cloak Mountain, Icelandic folklore holds it to be one of the gates to purgatory, guarded by witches.

Hekla in Icelandic is the word for a short hooded cloak which may relate to the frequent cloud cover on the summit.

An early Latin source refers to the mountain as Mons Casule.

Hekla had been dormant for at least two hundred and fifty years when it erupts explosively in 1104 (probably in the autumn), covering over half of Iceland (fifty-five thousand square miles) with 1.2 square kilometers / 2.5 square kilometers of rhyodacitic tephra.

This is the second largest tephra eruption in the country in historical times with a VEI of 5 like H3.

Farms upwind of the volcano in Þjórsárdalur valley (fifteen kilometers distant), Hrunamannaafréttur (fifty kilometers distant) and Lake Hvítárvatn (seventy kilometers distant) are abandoned due to the damage.

The eruption causes Hekla to become famous throughout Europe.

Stories, probably spread deliberately through Europe by Cistercian monks, told that Hekla was the gateway to Hell.
