Here goes Katla volcano again.
Earthquake activity in Katla volcano has been slowly increasing today (06-October-2016). It is not yet at the levels as it was week ago, but as Katla showed last week this change can happen rapidly and without much warning. Largest earthquake since this morning had the magnitude of 2,4 at 14:11 UTC. Other earthquakes so far have been smaller in magnitude. Other earthquakes have been smaller in magnitude.

The fact that current earthquake swarm is in a really tight location suggests that a dyke intrusion is possibly trying to drill its way out up through the crust at this location. I did see something similar before Bárðarbunga volcano erupted. It is not possible to know how long this process takes, since the crust is different between volcanoes. Then there is always the question if this process stops, at this moment I find that doubtful due how long its been going already. I’m expecting the earthquake activity in Katla volcano to increase until a new peak is reached or an eruption starts. Currently no eruption has started.

Off-line warning
Due to hurricane Matthews there is a risk of this website going off-line from tomorrow as the hurricane hits Florida and Orlando, where this website is hosted. I will take a backup of it later today just in case. At worst some comments might be lost and even some articles (if I update the website after I take my backup).
