Physical features and ecosystem
The fjord landscape is formed by glacial deposits. The average depth is 5 meters and the residence time
of water in the fjord is about 20 days. As to tidal variations

Wednesday (18.03) to review the
latest data.The deformation is occurring in the
same location as before, but at a slower rate. The uplift started in January
and halted temporarily at the end of February. The most recent data show that
since the beginning of March the uplift is about 20 mm. “The deformation now
seems to be quite slow, slower than in January. Indeed, 20 mm is a small uplift

system. The eruptions were effusive
(non-explosive) fissure eruptions erupting on 1-10 km long fissures. No
explosive eruptions are known from this system. The largest eruption in the
swarm, from 13th century, formed Arnarseturshraun lava (estimated 0,3 km3 and
20 km2). Historically, the duration of these eruptions spans from a few days up
to several weeks. Seismic activity is very common

Abstract. The Little Ice Age maximum extent of glaciers in
Iceland was reached about 1890 AD and most glaciers in the
country have retreated during the 20th century. A model for
