The snow cover above the topmost row did not move or break up. It is possible that this is due to the supporting structures but as the fracture line to the west of the structures is approximately at the elevation of the top row it is not clear whether the snow cover above the structure would have been released as an avalanche in the absence of the structures.
In a few locations one could see

making process and a part of the work within
information management is to investigate how the
process of information dissemination to the energy
companies can be improved.
In some cases there is increased inflow in the
hydropower plants, the snow storage will increase
abow certain elevation and spring and autumn floods
will change.

at Bárðarbunga was measured
with the radar system of Isavia’s aircraft. The measurements show large changes on
the ice-surface. Up to 15 m subsidence has occurred in the centre of the caldera,
which corresponds to a volume change of 0.25 km3. The shape of the subsidence
area is in accordance with the elevation of the caldera floor having lowered by that
amount.

Heading: West–northwest from the eruption site.
Colour: Light, low-lying clouds of steam observed over the eruption site, together
with occasional bursts of grey to black-coloured cloud, which rose to up to
half of the total height of the eruption plume. Above this level, the plume
was lighter in colour with a capping of white cloud

and the flow of glaciers is used to re-
construct the 20th century retreat history of Hoffellsjökull, a
south-flowing outlet glacier of the ice cap Vatnajökull, which
is located close to the southeastern coast of Iceland. The
bedrock topography was surveyed with radio-echo soundings
in 2001. A wealth of data are available to force and constrain
the model, e.g. surface elevation maps from ∼1890

and a river close to the site and a lake nearby. Elevation is 65 m above sea level, distance from the sea is 26 km and distance to towns of about 1000 inhabitants is about 15 km. This is an ideal inland background station at 64oN 21oW.

(three-day earthquake rate, in red) from 2011. Seismicity is often elevated
during June, July and August (these months are shown in light blue). In
dark-blue, the air temperature at Reynisfjall is shown, adjusted to the elevation
of the Katla caldera. A couple of explanations have been suggested to explain
the seasonal seismicity, for example increased pore
