parameters major earthquakes
2015/9/30
Source parameters for three majo earthquakes in the East African rift are re-computed from historical seismograms and bulletins. The main shock and the largest foreshock of the August 25, 1906 earthqu...
Evolution of magnetotelluric,total magnetic field,and VLF field parameters in Central Italy:relations to local seismic activity
Magnetotelluroc tectonomagnetism VLF waves
2015/9/28
Magnetotelluric data were collected at Collemeluccio (41.72°N, 14.37°E) in Central Italy from summer 1991 to spring 1998. Analyzed by means of tensor decomposition on the geoelectric potential and rob...
Source parameters of the Izmit-Bolu 1999 (Turkey) earthquake sequences from teleseismic data
source inversion complex earthquake North Anatolian Fault
2015/9/28
Body waveform modelling and far-field displacement spectral analyses were used to study the source parameters of five of the largest earthquakes of the (Izmit-Bolu) Turkey 1999 sequence. The derived s...
Evaluation of the seismic hazard parameters for selected regions of the world:the maximum regional magnitude
maximum regional magnitude activity rate seismic hazard parameters seismic hazard level k-index circum-pacific belt
2015/9/28
Parameters of seismic hazard are estimated by the application of the maximum likelihood method. The technique is based on a procedure which utilizes data of different quality, e.g., the ones where the...
