The goals of seismic impact assessment can be achieved by seismic monitoring systems and seismic impact simulator. Seismic monitoring system, for the purpose of hazard analysis, local site effects analysis, vulnerability analysis, and estimation of loss, is one application of SHM in earthquake engineering. A prototype, conceptual seismic impact simulator integrating SHM, FEM, GIS, and Virtual R...

Introduction: Over the past several years, we have presented new data and proposed a cold-based glacial hypothesis for the Tharsis Montes fan-shaped deposits [14], which were first identified and analyzed using Viking data [5-8]. Based on stratigraphic relationships with young lava flows in Tharsis, we know that the deposits are of midto late-Amazonian age [8,9], but we have little information ...

Taking the fluvial reservoir of Neogene Minghuazhen Formation in Bozhong S oilfield China as an example, a detailed study interlayer was conducted. From perspective sedimentary genesis interlayer, three types are summarized and analyzed, namely, fine grain sediment inter peak channel, suspended post flood abandoned channel sediment. At same time, combined with seismic waveform analysis, distrib...

We present a new crustal cross section through the east-west trending ultrahigh-pressure (UHP) Dabie Shan orogenic belt, east central China, based on a 400km-long seismic refraction profile. Data from our profile reveal that the cratonal blocks north and south of the orogen are composed of 35-km-thick crust consisting of three layers (upper, middle, and lower crust) with average seismic velocit...

296 A wellfield (Boise Hydrogeophysical Research Site or BHRS) is being developed in Boise, Idaho, for hydrologic and geophysical research in a shallow, coarse (cobble-and-sand), alluvial aquifer. Our goal is to develop cost-effective methods for quantitatively characterizing the distribution of permeability in heterogeneous alluvial aquifers using hydrologic and geophysical techniques. Respons...

this study aims to develop seismic fragility curves for a typical pile-supported wharf. fragility curve is one of the popular tools in seismic performance evaluation of a structure. the software flac2d was used to simulate the seismic performance of the wharf structure. using eight time history records, occurred in past, as seismic loading, incremental dynamic analysis (ida) was applied for sei...

Outcrop analogs play a central role in understanding subseismic interwell depositional facies heterogeneity of carbonate reservoirs. geologists rarely utilize near-surface seismic data due to the limited vertical resolution and difficulty visualizing signals as “band-limited rocks.” This study proposes methodology using combination forward modeling conditional generative adversarial network (cG...

To understand the seismic damage characteristics of bottom frame-wall buildings and to study their seismic performance, the seismic damage outcomes of  bottom frame-wall structures in Du jiang weir by the Wen chuan earthquake on May 12,2008, China were field observed and studied. The assesment of the seismic damage to the bottom frame-wall masonry in Du jiang weir urban showed that the damage t...

A detailed outcrop and sub-surface analysis was completed on the Peay Member sandstone (Frontier Formation) in the northeast Bighorn Basin, Wyoming, building on previous work by Clark (2010) and Hutsky (2011). Regional correlations reveal the sandstone body to be digitate in planform geometry, elongate along depositional dip, and restricted across depositional strike. It is interpreted to be th...

For decades, how to improve the resolution limit of seismic data has been a concern for seismologists. this reason, several geoscientists have proposed various methods improving bandwidth data. Discovering an easy and scientifically reliable means would undoubtedly help geophysicists interpret more complex details subsurface geology. In study, we transformed bandlimited time-domain frequency do...
