Hyaloclastite ridge showing sandstone, Grimsvotn volcanic eruption, Icealnd
On Mt Grimsfjall, Hyaloclastite ridge is a linear, steep-sided ridge formed by a subglacial fissure eruption and are a prominent landscape feature of Iceland. The last Grimsvotn eruption began on May 21, 2011 spewing tons of ash; initially the plume was over 20 kilometers high. Volcanic ash is an extreme danger to jet engines closing airspace in Iceland and parts of Europe. Grimsvotn is Iceland's most frequently erupting basalt volcano located under Vatnajokull Ice Cap; the largest glacier in Europe. Date photographed May 30, 2011
