Ambient air pumped for an hour into a ~10 litre aluminium container, thereby collecting a compressed sample of great volume, done weekly or semi-monthly depending on season. Various components are analysed, investigating the stability of atmospheric composition.

methodology is widely utilized by many automatic earthquake detectors, but instead of having
window lengths on the order of minutes, like the ALERT module, they have window durations
on the order of seconds. A longer STA window duration will make the module less sensitive to
small signals (Trnkoczy, 1999). Additionally, the total duration of the STA and LTA windows
may not exceed 24 hours

processes in order to be able
to compare and evaluate alternative management regimes
and to implement and support transition processes if
required.
This article also addresses the question whether a higher
level of AIWM is showing a different response in coping
with floods and droughts than case-studies with a lower
level of AIWM. This will be done by looking at their
adaptation strategies

), 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 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
