The reason for this earthquake activity is inflation in Bárðarbunga volcano. This is pushing the crust that fell down in the eruption of 2014 – 2015 in Bárðarbunga volcano (Holuhraun area) up again and that friction creates earthquakes. New magma is flowing into shallower magma chamber (at depth of ~10 km) from more depth under the volcano (20+ km depth). This started in September-2015 and is going to continue for many more months, maybe until next eruption in Bárðarbunga volcano.

    Maybe you could list the specific part of the non-English language that I could click on to change the page to English.
