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...
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
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 ...
搭载于ENVISAT卫星上的SCIAMACHY是目前唯一采用近红外波段观测大气温室气体(CO2,CH4,CO)的高光谱传感器.与其它热红外卫星传感器如AIRS、MOPITT、IASI等相比,SCIAMACHY用于CO探测的近红外波段对与人类活动密切相关的底层大气具有更高的敏感性.但无论从光谱角度(该波段CO吸收强度较弱,且存在很强的CH4和H2O重叠吸收),还是从SCIAMACHY仪器问题的角度(...
Numerical simulation and first-order hazard analysis of large co-seismic tsunamis generated in the Puerto Rico trench: near-field impact on the North shore of Puerto Rico and far-field impact on the US East Coast
Numerical simulation first-order hazard analysis large co-seismic tsunamis generated the Puerto Rico trench
2010/10/21
We perform numerical simulations of the coastal impact of large co-seismic tsunamis, initiated in the Puerto Rican trench, both in far-field areas along the upper US East coast (and other Caribbean is...
AbstractField investigations allow to constrain the co-seismic surface rupture zone of ～400km with a strike-slip up to 16．3 m associated with the 2001Mw 7．8 Central Kunlun earthquake that occurred alo...
Abstract27×10-8）大致呈EW向分布，长约800 km，宽约280 km，面积约22.41万km2。整个CO逸出区[WTBX]φ[WT](CO)为2002年正常值的1.57～4.10倍，与从卫星热红外图像上发现的2000年4月29~30日在青藏高原上的大面积多处孤立升温有较好的一致性，且这种CO逸出的现象至少在2000年4月30日之前的数天内是持续存在的，它们都是200...
Detecting co-seismic displacements in glaciated regions: An example from the great November 2002 Denali earthquake using SPOT horizontal offsets
Alaska Denali earthquake earthquake rupture SPOT offsets
2014/4/15
We use SPOT image pairs to determine horizontal offsets associated with the Mw 7.9 November 2002 Denali earthquake in the vicinity of Slate Creek, AK. Field measurements and aerial photographs are use...
Co-Registration of Optically Sensed Images and Correlation (COSI-Corr): an Operational Methodology for Ground Deformation Measurements
Co-Registration Optically Sensed Images Correlation an Operational Methodology Ground Deformation Measurements
2014/4/15
Recent methodological progress, Co-Registration of Optically Sensed Images and Correlation, outlined here, makes it possible to measure horizontal ground deformation from optical images on an operatio...
Co-registration and correlation of aerial photographs for ground deformation measurements
Aerial Photography Change detection Registration Correlation
2014/4/15
We describe and test a procedure to accurately co-register and correlate multi-temporal aerial images.We show that this procedure can be used to measure surface deformation, and explore the performanc...
Co-seismic slip from the 1995 July 30Mw=8.1 Antofagasta, Chile, earthquake as constrained by InSAR and GPS observations

2014/4/9
We analyse radar interferometric and GPS observations of the displacement field from the 1995 July 30Mw=8.1 Antofagasta, Chile, earthquake and invert for the distribution of slip along the co-seismic ...
