The Longmenshan forms the eastern margin of Tibetan Plateau adjacent to Sichuan Basin. This range is anomalous because it formed despite low convergence and slip rates without development a foreland basin. devastating A.D. 2008 Wenchuan earthquake (Mw = 7.9) has renewed debate about tectonics Longmenshan. A magnetotelluric (MT) study was undertaken subsequent investigate crustal structure Longmenshan, inversion data reveals low-resistivity (high-conductivity) layer at depth ∼20 km beneath...
SUMMARY The 2008 Wenchuan earthquake, which occurred on the eastern edge of Tibetan Plateau, produced significant time-dependent post-seismic deformation in northeastern Plateau. To explore spatio-temporal evolution crustal and its impact nearby active faults due to we first solve velocity fields, strain rates slip major at different stages earthquake cycle, based GPS observations spanning approximately 10 yr before after earthquake. results show that: (a) during late interseismic phase,...
ABSTRACT Earthquake forecasting models play a vital role in earthquake occurrence assessment. Despite improved availability of seismic and geodetic data processing techniques to produce high-resolution catalogs deformation history, the implementation with remains challenge. In this study, we utilize seismicity Global Navigation Satellite Systems (GNSS) propose time-independent grid-based regional likelihood for southeastern Tibetan plateau (RELM-TibetSE). First, solve GNSS velocity field...
Abstract An updated GPS velocity field and set of focal mechanism solutions have allowed us to quantify the detailed tectonic deformation Northeast Tibet. By employing block kinematic modelling, we show how relative motion modelled blocks is accommodated by on major fault structures across region, from Eastern Kunlun Range Qilian Shan, with slip rate decrease centre towards east in Kunlun, Haiyuan Altyn Tagh Fault, as well strain partitioning these faults. The deflection both derived strains...
The Qilian fold-and-thrust belt (QFTB) offers an excellent example to demonstrate the strain transition from strike–slip shearing oblique crustal shortening, which plays important role in dissecting stress propagation of Indian–Eurasian convergence plateau interior surrounding blocks. Various geological or numerical models have attempted describe regional tectonic characteristics QFTB. However, these only interpret one part deformation behaviors QFTB, and distribution across along QFTB as...
A base band sum-difference scenario used in digital monopulse radar system is introduced this paper. The angle measurement error caused by the amplitude and phase imbalance of receiving channels also analyzed based on structure. calibration method as well compensation result represented.
Summary Utilizing statistical tests to evaluate earthquake forecasting models is crucial improve strategies for seismic hazard assessment. We develop a novel evaluation method alarm-based forecast, taking into account the magnitude of energy and impact area earthquakes, instead using solely event number epicenter locations in conventional approaches. First, we derive scale-law Seismic Area by statistically analyzing coseismal maps past M ≥ 7.0 earthquakes. Second, proportionally allocate...
It is critical in the study of crustal deformation to reduce TRF-related system errors and enhance accuracy GPS coordinate time series. To associated with series, which are related terrestrial reference frame (TRF) realization, we develop a recursive TRF realization strategy regional data processing. We have processed whole set CMONOC (Crustal Movement Observation Network China) by using Bernese 5.2 software employed controlled datum removal (CDR) filter deal rank defect problem daily normal...
Technological parameters of semi- bionic extraction( SBE) flavones from chestnut flower were optimized using single factor and orthogonal experiment,and the antibacterial activity was investigated by measuring inhibition zone minimum inhibitory concentration( MIC).The results showed that optimum extracting conditions time 10 min,the temperature 80 ℃ material- to- liquid ratio 1∶ 20( m∶ V).Under these optimal conditions,the extraction yield of( 6.76% ± 0.11%) obtained. The exhibited against...
This study investigated the durability of recycled lime-fly ash treated aggregates (RTA) as pavement base and sub-base layers. First, both physical chemical properties waste aggregate (WTA) materials were tested. Then, RTA designed according to specifications further examined for its long-term including shrinkage, freeze-thaw, fatigue permeability. The actually cement-stabilized RTA, a stabilized blend 70% WTA 30% virgin layer, 100% respectively. Test results follows: 1) particle surfaces...
