One of Iceland's most feared volcanoes, Hekla, looks ready to erupt, with measurement instruments showing likely magma movement, an Icelandic geophysicist told AFP on Wednesday.

"The movements around Hekla have been unusual in the last two to three days and have been recorded in five very precise metres placed around Mount Hekla," University of Iceland expert Pall Einarsson said, adding that while this might not necessarily mean an immediate blast, "the volcano is ready to erupt."
