A strong earthquake
29.5.2008
Today, Thursday 29 May 2008 at 15:45, an earthquake of the size 6.1 on the Richter scale occurred in Southwest Iceland. It was found in Reykjavík and elsewhere. Its origin was near mountain Ingólfsfjall, 5 km northwest

GMT explosive activity increased again and the plume rose to about 7.5 km height. The increased activity was observed for about 20 minutes, then the activity dropped down at 21:15 GMT and increased again at 21:45 GMT. This pulsating activity is also clearly seen on tremor plots (click to enlarge) from near seismic stations, i.e. at Grímsfjall, located 5 km east of the eruption site

stations, i.e. at Grímsfjall, located 5 km east of the eruption site, and at Skrokkalda located 50 west of the eruption.
Water is clearly seen in the fissure (photo below). The eruptive activity is now concentrated at two small vents surrounded by a thin circle of tephra. The eruption plume drifted slowly southwards but ash fell down from the plume into a brownish layer of ash which spread out over

Oblique spreading leads to extensive volcanism and large earthquakes, a combination that is otherwise
uncommon in Iceland. The fissure swarms of individual volcanic systems contain normal faults and
fissures, with a NE-trend, also quite oblique to the plate boundary. The fissure swarms fade out towards
the NE and SW as they extend into the plates on either side. Overprinting this pattern

pressures and temperatures. He found that at shallow depths one expect in general brittle and stable slip
(not unstable slip, earthquakes). This prevailed for the top 5 km of granitic crust. Between 5 and 20 km
depth one got brittle unstable slip and when temperature and depth increased one got eventually

The first session started with an introduction to the sector / case considered, followed by a
brief general discussion on the outlined features of the sector. The rest of that session was used
to deliberate on questions 1 to 4. In the second break-out session the rest of the questions 5 to
7 were addressed. The third
