A glacial flood, possibly from an eruption of Katla volcano under the Mýrdalsjökull icecap has damaged Highway number 1 by the river Múlakvísl. The bridge across Múlakvísl has been damaged and the road is closed between Höfdabrekka, east of Vík, and Skálm River, near Álftaver. So far the eruption is not large, but people have
2011-07-06T23:05:56.634+10:00Hekla volcano in Iceland is showning signs of unrest. Signs of possible magma movement under the volcano has been detected for the past few days. Since 1970, Hekla volcano has erupted about every 10 years. The initial phase of each Hekla eruption is always highly explosive. The duration and magnitude of the explosive phase is directly correlated with the length of the preceding repose period
