Icelandic Met Office has posted an interesting analysis of the last weeks earthquake on the Reykjanes. But this earthquakes where connected to Krýsuvík volcano activity. By relocating the earthquakes, it is possible for Iceland Met Office to see better how long and how deep the fault that created this earthquakes is. In this case, it was around 2 km long and the movement was east-west, like the one found on SISZ.
The orange ones are re-located using relative locations. I am not sure how this technique works. But it often gives better image on what is going on with the earthquakes. Both in terms of the fissure making the earthquakes and the depth where they are taking place.
The fissure in question was on N-S axes and is inclined about 70° in west direction. According to IMO, the aftershocks suggest that movement of this fissure was right slip, along with minor drop in it. That means this according to IMO. The west part of the fissure moved to north and down, while the west part of the fissure moved to the south and little bit upwards. According to IMO. This movements happens in SISZ on large fissures there (when they break).
I am currently waiting for more earthquakes in this area. This activity is not over in my opinion any time soon.
Source of data: Week 9 – Iceland Met Office (Icelandic).
Other: I am sorry for lack of updates. There has not been anything special going on and I have been working on confirming getting an apartment in May 2012.
