I it's looking like this time the dyke will fail to erupt.
It's being suggested that it is still looking for the easiest route out. Some say it'll erupt right below, or even on, Mt keilir, while others claim that the magma is being bounced back to the more traditional (in recent years) eruption site. All we can do at this stage is wait and see.
