enjoyable time during this work, both in the office and in the field.
This work was carried out as a part of the Skaftá cauldrons research project which
was funded and supported by the Icelandic Centre For Research (RANNÍS), Kvískerja-

of how
events unfold over time (Gallopı´n et al., 1997; Raskin et al., 2002).
The key element in the context of this paper is that scenarios can be
either qualitative (told in words) or quantitative (told in numbers).
In that spirit, many of the recent (global) scenario exercises have
been structured as what has become known as a Story-and-
Simulation (Fig. 1) approach (Alcamo, 2001).

afterwards,
strong social interactions and converging prosperity worldwide, rapid development and spread of
new technologies, and a balanced use of fossil and non-fossil energy sources.
The monthly fields from the various general circulation model (GCM) runs are interpolated onto a

boundary at 47 N, the study domain covers Newfoundland, but excludes various marginal and
inland seas with significant independent storm activity, such as the Mediterranean and Adriatic
Seas, as well as the Black and Caspian Seas. The northern boundary at 80 N takes the domain
up to Fram Strait, including Svalbard, but excluding

level in Skeidará waned. The last sign of a
crater explosion was seen at GRF early on 6
November, leaving only a weak tremor signal
from the remnants of the jökulhlaup. The
jökulhlaup fi nally ended in early December,
after ~0.8 km3 of water had drained from the
Grímsvötn lake (J. Hardardóttir, personal com-
munication, 2005).

Such landslides fall from a comparatively high
elevation, cause extensive disruption and upheaval of loose materials and soils in their
way, and can travel considerable distances uphill against opposing slopes.
Secondly, there are medium-sized or large, rapid debris flows that are released from com-
paratively high elevations and are confined to gullies as they travel down the mountain-
side, similar
