While extracting land cover from remote sensing images, each pixel in the image is allocated to one of the possible class. In reality different land covers within a pixel can be found due to continuum...
The temporal and spatial variations of low frequency geomagnetic pulsations at polar cusp and cap latitudes
Geomagnetic pulsations Antartica
2015/10/8
Geomagnetic field measurements at two Antarctic stations are compared during two weeks in the local summer (January 1-15, 1992). Low frequency (0.6-6 mHz) pulsations are observed at each station near ...
Temporal characteristics of some aftershock sequences in Bulgaria
Aftershock Aftershock decay rate secondary Aftershock sequences

Deep-sea borehole seismological observatories in the western Pacific: temporal variation of seismic noise level and event detection
deep-sea borehole observatory broadband seismometer seismic noise level
2015/9/7
Seismological networks provide critical data for better understanding the dynamics of the Earth; however, a great limitation on existing networks is the uneven distribution of stations. In order to ac...
Earthquake forecasting in Italy,before and after Umbria-Marche seismic sequence 1997.A review of the earthquake occurrence modeling at different spatio-temporal-magnitude scales

The main goal of this work is to review the scientific researches carried out before and after the Umbria-Marche sequence related to the earthquake forecasting/prediction in Italy. In particular, I fo...
Forecasting Italian seismicity through a spatio-temporal physical model: importance of considering time-dependency and reliability of the forecast
spatio-temporal physical model considering time-dependency
2015/8/28
We apply here a forecasting model to the Italian region for the spatio-temporal distribution of seismicity based on a smoothing Kernel function, Coulomb stress variations, and a rate-and-state frictio...
