Grímsfjall volcano continues to prepare for a new eruption

As I did mention in a blog post from 16. January 2012. Grímsfjall volcano is preparing for a new eruption. That progress has not slowed down at all. I am rather sure that the eruption prepare progress in Grímsfjall volcano has sped up. But this is nothing confirmed at the moment. I am just noticing slow increase in earthquakes from Grímsfjall volcano.

It is impossible to know for sure when next eruption starts in Grímsfjall volcano. But at the current time, the clock is ticking down faster then it did before in my opinion. As is known from history. Grímsfjall volcano has erupted sometimes the year after. Even after a big eruption. As was the case last year (2011), when it had the largest eruption in 140 years.

    I am assuming this is approaching harmonic at the lower end for Grmsfall Jon? I had noticed new activity on the glacier, but didn’t think it sufficient to suggest anything imminent, although there is so much strain across Iceland it could in reality go anywhere at any time.

    Have you any other data on this?

    1. It seems that it’s nothing serious, I think lack low frequency increased from 0.5 to 1 Hz

  2. hello everyone

    hekla had three earthquakes in the two days, not too sure if it in the volcano itself or just near to it but the largest is at 2.1 mag and at 7.1 kms might mean magma is on the move. Hekla only gives a few hours warning before its erupts or none at all..
    Frimann what do think is happern at hekla this morning could this lead to a eruption or are these earthquakes just happern part of a flault line near the volcano.
    thankyou!! jack

  3. Most of those quakes appear to be along existing fissure/fault lines. Is Grimsfjall displaying any harmonic tremor?
