Percolating water from the melt-
ing snow may have increased the rate of movement. Seismic data
indicate that a sudden movement occurred around 40 minutes be-
fore the slide, but at 23:24 the failure point was reached and the
rockslide was released.

METHODS AND DATA
This article is based on empirical data that originated
from the analysis of the participatory exercise in the
Dhuenn basin. The strong involvement of
researchers from two research projects (NeWater[1]
and ACER[2]) linked by a joint case study led to the
variety of sources available for exploration,
including

and Herðubreiðartögl. A few small ones were also detected in the dyke intrusion.
30 December 2014 - now confirmed 82.8 km²
Two days ago, difficulties in approaching the lava led to doubts about the newest estimate of its size. The Institute of Earth Sciences has now confirmed that the lava is almost 83 km², see map (enlarge).

days considered here, are listed in Table 1. Changes in orbital parameters are mainly significant
between the last and the previous two cases, with a drop in noontime solar intensity, defined as
the sine of the sun altitude angle, by 14–17%. This difference needs to be taken into account
when comparing shortwave radiation fluxes between the different cases.
The diurnal cycles of net

there also stopped before they led to a slope failure. A year later, in November
18
2002, multiple tension cracks formed in Botnabrún during a heavy rainstorm after a long wet
period. Most of the cracks that formed during the rainstorm occurred in the upper part of Botna-
brún, between Skuldarlækur and Nautaklauf. These movements led to the release of two debris
slides, just west of Búðará

and Langjökull. The number of days where temperature never exceeds 0°C is expected to
drop by half in the RCP8.5 scenario by the end of the century. In comparison, Vatnajökull is
expected to retain three quarters of its cold days.
In Figure 13 histograms are made for minimum temperatures in the entire Iceland domain.
