Today around 13:00 or 14:00 UTC (not sure exactly when) there was a possible minor harmonic tremor at Grímsfjall volcano. But earlier today I did write about the fast rise that is happening at Grímsfjall according to GPS data. It seems that things might get interesting soon if the current trend continues as it has for the past few weeks.
I do not believe that this is weather interference that I am currently seeing.
