Activity summary:
The seismicity at Grímsvötn is back to normal level (with few earthquakes detected over the past 3 weeks). No unusual gas has been detected in Grímsfjall over the past months. There is still uncertainty on assessing the status of the cauldron which deepened during the last flood, so it is still difficult to evaluate the level of the geothermal activity around Grímsvötn. In light of the current available observations, the aviation color code for Grímsvötn is moved back to green.
