Deep earthquake activity in Katla volcano

Today (23-June-2016) a deep earthquake swarm took place in Katla volcano. None of the earthquakes that took place where strong, but many of them where deep. The deepest earthquake had the depth of 28 km, at this depth it’s only magma that creates earthquakes.

Other interesting feature that showed up is a dyke intrusion in the caldera wall to the south, it is located almost directly north of Vík í Mýrdal village. This dyke intrusion appeared in 2011 after the minor eruption in July that year (this is my view, at the moment it has not been approved by scientists). It is unclear how this dyke intrusion is evolving, but there might be some risk of eruption from it if the pressure increases. Currently there is nothing that suggests an eruption is about to happen.

  1. Hi everyone! Frequencies rising again in Dyn… it’s possible a jökulhlaup is starting in Bardarbunga area?

    1. A minor glacier flood has been confirmed from the western Skaftár cauldron. I’m going to write about it little later on. I just have to get to the store first.

  3. this is amazing – i was just writing to friends last week and placed bets with them for katla for the 24th

    it is deep low pressure combined with the ice melting and pressure release.

    Fantastic stuff to hear of a quake , right at the right time for one ..

    In ireland we believe we can feel the magma. it whistles and signs a sad song. and is perhaps some way connected with iceland.

    Journey to the centre of the earth.
