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...
The fine structure of the dynamics of seismicity before earthquakes in the area of Reggio Emilia (Northern Italy)
seismicity earthquakes prognostic parameter seismic quiescence foreshock activation
2015/9/30
We present the results of studies of seismicity in the Reggio Emilia area (Northern Italy). The Istituto Nazionale di Geofisica instrumental earthquake catalogue (1975-1996) reported about three moder...
Significance test for seismicity rate changes before the 1987 Chiba-toho-oki earthquake (M 6.7) Japan
quiescence seismicity rate increasa quantitative analysis significance test the 1987 Chiba-toho-oki earthquake
2015/9/30
A precursory seismic quiescence lasting 1.5 ± 0.5 years was observed prior to the 1987 M 6.7 Chiba-toho-oki earthquake, Central Japan. This event was the largest mainshock to occur in the region in 60...
Some preliminary results of a worldwide seismicity estimation: a case study of seismic hazard evaluation in South America
Seismicity maximum observed magnitude seismic moment seismic momente rate
2015/9/30
Global data have been widely used for seismicity and seismic hazard assessment by seismologists. In the present study we evaluate worldwide seismicity in terms of maps of maximum observed magnitude (M...
Analysis of the seismicity of Southeastern Sicily: a proposed tectonic interpretation
Historical seismicity Macroseismics source parameters quaternary tectonics seismogenic faults hyblean plateau SE Sicily
2015/9/30
Southeastern Sicily is one of the Italian regions with high seismic risk and is characterised by the occurrence in the past of large destructive events (MS = 6.4-7.3) over a territory which is densely...
Space-time variations of the Umbria-Marche region instrumental seismicity
b value seismicity Apennines
2015/9/29
In the Umbria-Marche region, space and time variations concerning the b value were studied by instrumental seismicity from January 1987 to May 1999, according to the Bender method. Data were divided i...
Tectonics and seismicity of the ApulianRidge south of Salento peninsula(Southern Italy)
tectonics seismicity multichannel seismic reflection apulia lithosphere flexsure
2015/9/28
Multichannel reflection seismic data were acquired south of the Salento peninsula, in an area where crustal seismicity has been recorded. Seismic profiles show the presence of small grabens bounded by...
