Thats not so concerning at all, the sttimnaerers were down in the -20'000 range a few days ago. this looks purely like changes in atmospheric pressure (weather). I think what we should look out there is:As long as BUR and STO behave similiar, theres nothing going to happen. When Burfell takes the Opposite direction of STO, then we should watch out.why do i think this? some days ago someone posted a link with a picture of the MET office during the hekla eruption in 2000. There you could clearly see the strain lines of STO and BUR. but what i dont know is why the strainrates for HELLA are changing that much and that often (something going on in the SIZ)
