Sorry for the late article. I’ve been busy in other project that involves taking a lot picture and putting them up on my Instagram that can be found here.
Two earthquake swarms have appeared that I am now keeping an eye out for. This is earthquake activity in Grímsvötn (Grímsfjöll) volcano and then in Þórðarhyrna volcano (Thordarhyrna). Last time Þórðarhyrna erupted was in the year 1902 and that was at the same time an eruption took place in Grímsvötn volcano. Over the last few months there has been increase in earthquake activity in Þórðarhyrna and Grímsvötn volcanoes. Its not completely symmetrical increase in earthquakes, but close to it as of writing of this article. Last time Þórðarhyrna erupted without an eruption in Grímsvötn volcano was in the year 1887 (15th August) to 1889 (?).

It is going to be a serious problem if an eruption happens in Þórðarhyrna volcano because that volcano is completely covered with a glacier that is up to 200 meters thick or thicker. Other risk factor is that Grímsvötn volcano might erupt outside of the caldera resulting in glacier floods and other problems.
