was magnitude 3.3 on the same day, 29 August. Following this earthquake, relatively little seismicity has been detected in the caldera.Throughout the summer, electrical conductivity levels in Múlakvísl, which drains from the eastern side of Mýrdalsjökull, have remained unusually high, reflecting a constant source of geothermal meltwater. Together with increased conductivity, there have been frequent reports

Small glacial outburst floods around Mýrdalsjökull

Floodwater continues to drain from geothermal sources beneath Mýrdalsjökull into the rivers Múlakvísl and Jökulsá á Sólheimasandi. Conductivity levels in both rivers remain higher-than-normal

in seismicity are common at Katla and the ongoing activity within the caldera is similar to summertime unrest observed in 2012 and 2014. Often this increased seismicity occurred in association with drainage of meltwater from several known ice-cauldrons, formed due to hydrothermal activity, as observed almost annually. Since late June 2016 there have been three small floods in Múlakvísl river

Further heavy rainfall is forecast for this region today, so river levels will increase further

following additional input from overnight rainfall.Múlakvísl, Jökulsá á Sólheimasandi, Krossá in ÞórsmörkThe discharge of glacial rivers Múlakvísl and Jökulsá á Sólheimsandi is high due to sustained rainfall. Both rivers are at levels seen only during outburst floods in recent decades. Glacial river Krossá in Þórsmörk is exceptionally high, resulting in widespread inundation of the valley. Note
