Mad Jock,
There has been a significant drop in the number of earthquakes last few days and their have been none over Mag 4 for a day now.
Could it be that the scientists first likely scenerio has proved to be right, that it is about to stop ?.
However this volcano has defied everyone so far and understanding of volcanoes has had the rule book ripped up, doing things never observed before.
So it may still have a sting in the tail left over the coming weeks.
