Abstract Computing receiver function (RF) from teleseismic records can be affected by noise present in the seismic waveforms, and therefore, visual inspection is still preferred for quality control purposes. However, human handpicking RF lacks consistency requires a significant amount of time labor. From manually picked data sets, we have identified 4 features that effectively separate good bad RFs. Using these selected features, developed fuzzy clustering‐based method to automate...
Abstract We develop a data‐driven clustering method to evaluate velocity model using surface wave dispersion. This is done by first computing theoretical dispersion curves for 1‐D profiles of all the grid locations and then splitting resulting into certain number groups via K‐means clustering. The observed are also clustered following same procedure assessed comparing spatial patterns obtained synthetic data sets. applied two community models in southern California, CVM‐S4.26 CVM‐H15.1,...
Abstract The rate–state frictional law, coupled with the Coulomb failure stress changes (ΔCFS), is one of most popular physics-based models to forecast seismicity rate following a major earthquake. However, its effectiveness hampered by parameter uncertainties. To seek possible solutions for such uncertainties, this article carried out retrospective forecasts decade-long in Longmenshan region, China, after 2008 Mw 7.9 Wenchuan earthquake, and proposed methods constrain First, we derived...
Abstract We computed the stress-change tensor around 2015 Mw 7.8 Gorkha earthquake with two different rupture models: a simple uniformly dipping model and complex ramp-flat-ramp-flat fault-slip model. In general, Coulomb failure stress changes (ΔCFS) on optimally orientated faults based showed best spatial correlation aftershock seismicity. This close relationship was further verified by focal mechanism solutions of 17 intermediate-size aftershocks. The ΔCFS calculated from known mechanisms...
