Description :
A dark tephra layer, named a, is found in soils in East and Northeast Iceland. Its volume is approximately 2 km and it covers about 40 % of Iceland. An isopach map and grain-size study suggests that the tephra deposit forms a distinctly two-lobed layer and was erupted in the year 1477 from the central volcano Kverkfjoll, at the northern margin Vatnajokull.
