On May 4, 2012, a new system, known as the AIDA (Advanced Information and Data Acquisition) system for seismology, became operational as the primary tool to monitor, analyze, store and distribute seis...
Static stress transfer from the May 20,2012,M 6.1 Emilia-Romagna (northern Italy) earthquake using a co-seismic slip distribution model
Stress Transfer Slip distribution Italy
font style='font-size:12px;'>
2015/8/26
We model the static stress transfer for the May 2012 northern Italy earthquakes, assuming that failure of the crust occurs by shear. This allows the mechanics of the process to be approximated by the ...
Characteristics of flux-time profiles, temporal evolution, and spatial distribution of radiation-belt electron precipitation bursts in the upper ionosphere before great and giant earthquakes
