close to Hveragerði). Deformation measurements in recent years also indicate possible stress accumulations in the region, which might be released as a larger earthquake. Historic recordings show that earthquakes in that region can be up to M6.5. The last earthquakes of M>6 were in 1929 and 1968. Both of these events caused no major damage in the capital area. In modern times, however, urban

record data at regular intervals (e.g., every 10 minutes), while manual observations are made typically every three hours, or more.
Manual measurements of cloud cover, visibility and precipitation are essential, despite technological advances in automated measurement.
Satellite-based observations are an increasingly important factor in modern-day weather forecasting.

), for the purpose of predicting earthquakes, has been described as the Holy Grail of
seismology, i.e. highly desirable goal but with elusive results. Preseismic signals of the order of 10–
20%, reported in the 1960ies and 1970ies, have not been convincingly reproduced. Lower level (0.5–
3.5%) coseismic and postseismic in situ changes have, however, repeatedly been reported. Due to lack

The cryosphere exists on all latitudes of the Earth and occurs in approximately one hundred countries of the world. While the cryosphere is an integrative element within the climate

approximately 140 earthquakes between 30 January and 22 April that year. The
reason probably being the depth of the seismic cluster, which was near the base of the
crust.
The purpose of this research is to analyze the seismic activity within Eyjafjallajökull
recorded by the SIL network during the period 1991–2006, in order to study the processes
that caused the heightened seismicity and uplift

The volume of storage in the subglacial flood path, reached a maxi-
mum of 35 Gl which corresponds to two-thirds of the total flood volume. The volume
of subglacial storage was an order of magnitude larger than could have been melted
with the initial heat of the lake water and heat formed by friction in the flow along the
flood path. The largest part of the space for subglacial storage

The gray planes represent depths at 0 km, 5 km and 10 km from the true surface. The colour code of the earthquakes indicates days as counting from 16th August which

Exploring reasons why the risks of natural hazards seem to be ignored
by H. Asbjørn Aaheim, CICERO
Researchers give different explanations to why the risks of natural hazards seem to be ignored by
individuals, and management strategies are often deemed inappropriate. This presentation combines
empirical evidence from various disciplines and theoretical insights in order to identify critical
