On 05-October and 06-October-2017 there was an strong earthquake activity in Bárðarbunga volcano. The first earthquake had the magnitude of 3,7 on 5-October and the second earthquake had the magnitude of 3,4 on 6-October-2017. The first earthquake was in the south-west part of the caldera an area that for some reason does not see a lot of earthquake activity. The magnitude 3,4 earthquake was in the usual place of north-east part of the Bárðarbunga volcano caldera.

Few other earthquakes happened in this activity, they where all smaller in magnitude. Largest of the aftershocks had the magnitude of 2,2 and all other earthquakes where smaller in magnitude.
Dear Jón,
I notice an increase in earthquakes and magnitude of those eartquakes in Hvannadalshnjúkur.
More quakes between MW 1 and 2.
Kind regards,

That activity has been noticed by Icelandic Met Office, me and others. It is clearly magma that is creating this earthquake activity. From what I can tell nobody knows if this is normal or not. Last time increase like this happened (not quite as big as current activity) it got quiet again after few weeks of activity. I don’t know if that happens now.
I hope the website is now faster since it is hosted in the UK.
