Hekla 3 eruption

From Wikipedia, the free encyclopedia

The Hekla 3 eruption, dated to 1159 BC, is considered the most severe eruption of Hekla during the Holocene.[1] It may have triggered an eighteen-year span of climate worsening that is recorded in Irish bog oaks.[2][3] The eruption is detectable through Greenland ice-cores, the bristlecone pine sequence, and the Irish oak sequence of extremely narrow growth rings.[4] In 2000 skepticism concerning conclusions about connecting Hekla 3 and Hekla 4 eruptions with paleoenvironmental events and archaeologically attested abandonment of settlement sites in northern Scotland was expressed by John P. Grattan and David D. Gilbertson.[5].

In Sutherland, northwest Scotland, a spurt of four years of doubled annual luminescent growth banding of calcite in a stalagmite, otherwise unaccountable, coincided with the eruption.[6]
