The QuakeSim Problem Solving Environment uses a web-services approach to unify and deploy diverse remote data sources and processing services within a browser environment. Here we focus on the high-performance crustal modelling applications that will be included in this set of remote but interoperable applications. PARK is a model for unstable slip on a single earthquake fault represented as di...

Chaotic features of the macro-instability (MI) of flow patterns in stirred tanks are studied in this paper. Datasets obtained by measuring the axial component of the fluid velocity and the tangential force affecting the baffles are used. Two geometrically identical, flat-bottomed cylindrical mixing tanks (diameter of 0.3m) stirred with either pitched blade turbine impellers or Rushton turbine i...

A new methodology for table-form extraction and recovery with little previous knowledge is presented. The first module performs the identification of line intersections in a table-form, the second module detects and corrects wrong intersections produced by fault intersection segments or by table artefacts (smudges, overlapping of handwritten data and fault segments). In this module, an artefact...

Abstract Periodic components are of great significance for fault diagnosis and health monitoring rotating machinery. Time synchronous averaging is an effective convenient technique extracting those components. However, the performance time seriously limited when separate segments poorly synchronized. This paper proposes a new method capable periodic without external reference accurate period to...

Studying small repeating earthquakes enables better understanding of fault physics and characterization of fault friction properties. Some of the nearby repeating sequences appear to interact, such as the 'San Francisco' and 'Los Angeles' repeaters on the creeping section of the San Andreas Fault. It is typically assumed that such interactions are induced by static stress changes due to coseism...

Fuzzy theory and Bayesian network theory were based on the fault tree. The fault tree analysis method improved the fault analysis to obtain number of event's exact problem. Considering the characteristics of the fuzzy risk analysis at the same time, it also solved the problem of scale fault analysis modeling. The theory is applied to the cost of construction shield tunnel risk analysis, floatin...

We use high-resolution Synthetic Aperture Radarand GPS-derived observations of surface displacements to derive the first probabilistic estimates of fault coupling along the creeping section of the San Andreas Fault, in between the terminations of the 1857 and 1906 magnitude 7.9 earthquakes. Using a fully Bayesian approach enables unequaled resolution and allows us to infer a high probability of...

Abstract. The deposition of fluvial sediments in tectonically active areas is mainly controlled by tectonics, climate, and associated Earth surface processes; consequently, can provide a valuable record changes regional climate tectonic activity. In this study, we conducted detailed analysis the grain-size distribution modern from upper Min River, eastern Tibet. These data, combined with inform...

The 2021 Mw 7.3 Maduo earthquake revealed the significant seismic hazard of faults developed within Bayan Har Block eastern Tibet, China (e.g., Kunlun Pass–Jiangcuo Fault). Relocated aftershock data are in good agreement with Interferometric Synthetic Aperture Radar (InSAR) coseismic displacement field and investigations. In this study, we used point cloud fitting to model relocated aftershocks...
