In search of evidence of deep fluid discharges and pore pressure evolution in the crust to explain the seismicity style of the Umbria-Marche 1997-1998 seismic sequence (Central Italy)
fluid geochemistry/seismicity porepressure field Umbria-Marche 1997-1998 seismic sequence
2015/9/30
Starting soon after the first main-shocks of the long seismic sequence which has occurred along the Umbria-Marche boundary since September 1997, fluid geochemistry surveying was accomplished (around 2...
Geomorphology of the Gubbio Basin (Central Italy):understanding the active tectonics and earthquake potential
tectonic geomorphology normal fault seismogenic sources Umbria-Marche Apennines-29 April 1984 Gubbio earthquake
2015/9/16
The Gubbio Basin is a 22 km long, 4 km wide depression located within the North-Central Apennines fold-andthrust belt. The basin is bounded to the east by the Gubbio Fault, a W-dipping, normal fault d...
Rupture history of the 1997 Umbria-Marche (Central Italy) main shocks from the inversion of GPS, DInSAR and near field strong motion data

Seven missing damaging earthquakes in Upper Valtiberina (Central Italy) in 16th-18th century: research strategies and historical sources
missing earthquakes historical seismology Italian earthquake catalogues Upper Valtiberina
2015/9/8
The Italian earthquake catalogue is considered to be fairly complete starting from the 17th century and for classes
of earthquakes of magnitude greater than 5.5. However, dedicated historical researc...
