Foreshock activity and its probabilistic relation to earthquake occurrence in Albania and the surrounding area
Probability estimation of foreshock activity
2015/9/30
We investigate some characteristics of foreshock activity of moderate and large earthquakes which occurred in the present century in Albania and the surrounding area. Using a prediction algorithm, bas...
A probabilistic seismic hazard map of India and adjoining regions
Seismic hazard assessment India China UN/IDNDR earthquake continental collision active tectonics
2015/9/30
This paper presents the results of an exercise carried out under GSHAP, over India and adjoining regions bound by 0°N-40°N and 65°E-100°E. A working catalogue of main shocks was prepared by merging th...
Probabilistic seismic hazard maps for the North Balkan region
Seismic hazard map Pannonian basin Monte Carlo simulation Vrancea intermediate focus earthquake seismic hazard methodology UN/IDNDR
2015/9/29
A set of seismic hazard maps, expressed as horizontal peak ground acceleration, have been computed for a large area of Central and Eastern Europe covering the North Balkan area (Former Yugoslavia, Hun...
Probabilistic approach to earthquake prediction
precursors earthquake forecast statistical tests paleoseismology
2015/9/25
The evaluation of any earthquake forecast hypothesis requires the application of rigorous statistical methods. It implies a univocal definition of the model characterising the concerned anomaly or pre...
A probabilistic seismic hazard assessment for Greece and the surrounding region including site-specific considerations
seismicity of Greece probabilistic seismic hazard peak ground acceleration design earthquake procedure
2015/9/11
A probabilistic approach was applied to map the seismic hazard in Greece and the surrounding region. The procedure does not require any specification of seismic sources or/and seismic zones and allows...
Probabilistic seismic hazard assessment for Central Asia
PSHA for Central Asia Area source model Smoothed seismicity Frankel approach Woo approach Activity rates Central Asia earthquake catalog Seismic Hazard maps
2015/8/17
Central Asia is one of the seismically most active regions in the world. Its complex seismicity due to the collision of the Eurasian and Indian plates has resulted in some of the world’s largest intra...
Probabilistic seismic hazard assessment of Bishkek, Kyrgyzstan,considering empirically estimated site effects
PSHA Area source model Site effects Vs30 Site specific response spectrum ratio
2015/8/17
It is well known that variability in the surface geology potentially leads to the modification of earthquake-induced ground motion over short distances. Although this effect is of major importance whe...

Source Processes for the Probabilistic Assessment of Tsunami Hazards
Tsunami Hazards Source Processes
2015/7/17
The importance of tsunami hazard assessment has increased in recent years as a result of catastrophic consequences from events such as the 2004 Indian Ocean and 2011 Japan tsunamis. In particular, pro...
Fully probabilistic seismic source inversion – Part 1: Efficient parameterisation
Earthquake source inversion seismology non-linear uncertainty parameters the bayesian
2015/1/6
Seismic source inversion is a non-linear problem in seismology where not just the earthquake parameters themselves but also estimates of their uncertainties are of great practical importance. Probabil...
Relative impact of model quality and ensemble deficiencies on the performance of ensemble based probabilistic forecasts evaluated through the Brier score
model quality ensemble deficiencies ensemble based probabilistic forecasts Brier score
2009/11/11
The relative impact of model quality and ensemble deficiencies, on the performance of ensemble based probabilistic forecasts, is investigated from a set of idealized experiments. Data are generated ac...

probabilistic seismic hazard model cellular automata information theory
2009/11/9
We try to obtain a spatio-temporal model of earthquakes occurrence based on Information Theory and Cellular Automata (CA). The CA supply useful models for many investigations in natural sciences; here...
A probabilistic approach to heterogeneity in space plasmas:the case of magnetic field intensity in solar wind
probabilistic approach heterogeneity space plasmas magnetic field intensity
2009/10/30
Since the early 90s it was shown that Probability Distribution Functions (PDFs) of small scale differences (fluctuations) of several quantities in space plasmas display significant departures from Gau...
