or possible icequakes occurred about 12-20 km south of the volcano
yesterday evening.
GPS deformation: The GPS-station at Mt. Grimsfjall showed insignificant displacements
from 00:00 – 24:00 yesterday.
Overall assessment: Based on the development of plume height, ash fall in inhabited areas
in Iceland, number of lightning strikes, seismic tremor and ground
deformation, it is inferred

wide and
1000 m long shelf called Þófi, terminating at 80–100 m a.s.l., see Map 4. The inclination of
the shelf is 15 on average. The surface of Þófi is covered with unconsolidated glacial till and
landslide deposits and marked with five gullies. The brook called Þófalækur near the middle of
the shelf divides it into an inner and outer part. On the outermost part of the shelf, there is a small

currents. Because of the wide range of likely flow rheologies, three Manning's n values are assessed: 0.05, 0.1, and 0.15 s/m1/3. Results indicate that a large part of the lowland between the rivers Skaftafellsá and Breiðá (350 km2) is susceptible to flooding because of jökulhlaups descending the western and southern slopes of Öræfajökull. Characterised by average flow velocities in excess of 20 m/s
