toward ENE and it has been elongated considerably since yesterday. Since this
morning, a preliminary estimate of lava field extension is about 10.8 km2.
Seismic activity is still detected in the northern part of the dyke intrusion, along the
eruption site and extending south below Dyngjujökull. Event rates are lower than in

Seismic activity in Bardarbunga continues to be strong. The strongest earthquake since noon on Monday, 8.
December, was magnitude M4,9 on Tuesday at 18:00. About 20 earthquakes larger then M3,0 were detected since
Monday. In total about 180 earthquakes were detected in Bardarbunga since noon on Monday

assuming global sea-level rise of about 1 m towards the end of the century, the
relative sea-level change will range from a 40–60 cm rise in subsidence regions
to 10–180 cm sea-level drop-in regions of fast uplift. There is considerable
uncertainty in these estimates, with easily justifiable revisions of additional
25–40 cm of sea-level rise. However
