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...

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
