Engineering Analysis of Strong Motion Data from Recent Earthquakes in Sichuan, China
ground motion prediction equations NGA-West2 project code-based spectrum pulse-like ground motions
2018/6/13
Recent earthquakes in the Sichuan Province have contributed to significantly expand the existing ground-motion database for China with new, high-quality ground-motion records. This study investigated ...
ESTIMATION OF CO- AND POSTSEISMIC DEFORMATION AFTER THE Mw 8.6 NIAS-SEMEULUE AND Mw 8.5 BENGKULU EARTHQUAKES FROM CONTINUOUS GPS DATA
GPS earthquake postseismic deformation
2016/10/14
The Mw 8.5 Bengkulu earthquake of 30 September 2007 and the Mw8.6 28 March 2005 are considered amongst large earthquake ever recorded in Southeast Asia. The impact into tectonic deformation was record...
Monitoring of Earthquakes Activities along the Syrian Rift System (Left-Lateral) by Using Remote Sensing and GIS Database
Remote Sensing Thematic Geology Data Structures SAR DEM/DTM

This paper, based on the data of contemporary earthquakes in both Zhejiang Province and nearby districts, attempts to analyze firstly the historical damages, then study the distribution of an earthqua...
A detailed analysis of some local earthquakes at Somma-Vesuvius
Somma-Vesuvius seismicity focal mechanisms spectral analysis
2015/10/8
In this paper, we analyze local earthquakes which occurred at Somma-Vesuvius during two episodes of intense seismic swarms, in 1989 and 1995 respectively. For the selected earthquakes we have computed...
Observations of volcanic earthquakes and tremor at Deception Island - Antarctica
volcanic earthquakes tremor antartica
2015/10/8
Deception Island - South Shetlands, Antarctica is site of active volcanism. Since 1988 field surveys have been carried out with the aim of seismic monitoring, and in 1994 a seismic array was set up ne...
Coseismic displacement of the 27th September 1997 Umbria - Marche (Italy) earthquakes detected by GPS: campaigns and data
Umbria-Marche earthquakes IGM95 GPS coseismic displacement

On September 26,1997 two earthquakes of Mw 5.7 (00.33 GMT) and Mw 6.0 (9.40 GMT), occurred in the Umbria-Marche region (Central Apennines, Italy). The epicentres were located in an area of the Apennin...
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...
