But data in mounting and suggesting that magma is about to start flowing into the volcano at faster rates then before (via dike intrusions). Tungnafellsj\u00f6kull volcano has not erupted in historical times (at least no eruption is documented) so it is impossible to know for sure what happens next in this volcano. If an eruption where to take place it would be mostly basalt based on post sub-glacier eruptions (when they erupted is not known). Current earthquake activity might die down as it did in the year 2012 when (and earlier this year [2013] also) this swarm like activity at depth (15+ km) started to happen.<\/p>\n<p><em>Blog post updated at 04:36 UTC.<\/em><br \/>\n<em>Blog post updated at 04:46 UTC.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>There is currently ongoing interesting earthquake swarm activity in Tungnafellsj\u00f6kull volcano.
