Grumbling Katla?

Some speculation over at Wattsupwiththat about recent tremor activity under the Icelandic Caldera of Katla. The Icelandic Met Office still disagree that Katla is going to blow in the near future, because, as has been observed before, tremors alone do not an eruption make. There are other indicators.

Besides, this mornings screengrab shows no real 'swarm' type activity. For an eruption to be imminent, the tremors would also have to be far more closely spaced in time and depth.

But as Anthony rightly observes; "This may mean nothing, or it may be a prelude to an eruption. Either way it bears watching."

Exactly so.
