October 11th, 1996
An overflight this morning confirmed that the eruption continues, but activity may be declining somewhat. The eruption plume reaches an altitude of 11000 feet, less than in the last few days, and no cocktail explosions were observed. Poor visibility allowed limited inspection of the eruption site, but it could be confirmed that the eruptive crater is still covered with a column of water.
The ice cover of Grimsvotn has bulged up, confirming the huge amount of water has been accumulating in the Grimsvotn caldera. No signs of water escaping from Grimsvotn has so far been detected. Total volume in the caldera is estimated to be somewhat more than 2 km3.
