The impact of a and b value uncertainty on loss estimation in the reinsurance industry
Completeness seismic risk b-value average annual loss insurance
2015/9/30
In the reinsurance industry different probabilistic models are currently used for seismic risk analysis. A credible loss estimation of the insured values depends on seismic hazard analysis and on the ...
Impact of the Mt. Pinatubo volcaniceruption on the lower ionosphere andatmospheric waves over Central Europe
volcanic eruption lower ionosphere atmospheric waves radio wave absorption
2015/9/17
The very strong volcanic eruption of Mt. Pinatubo in June 1991 directly affected the troposphere and lower and middle stratosphere. Here we look at its effects in the mesopause region as revealed by t...
Candidates for multiple impact craters?: Popigai and Chicxulub as seen by the global high resolution gravitational field model EGM2008
