The 2008 Wells earthquake occurred on a northeast-striking, southeast-dipping fault that is clearly delineated by the aftershock swarm to a depth of 10-12 km below sea level. However, Cenozoic rocks and structures around Wells primarily record east-west extension along northto north-northeast-striking, west-dipping normal faults that formed during the middle Miocene. These faults are responsibl...

This paper presents an approach for slip prediction from a distance for wheeled ground robots using visual information as input. Large amounts of slippage which can occur on certain surfaces, such as sandy slopes, will negatively affect rover mobility. Therefore, obtaining information about slip before entering such terrain can be very useful for better planning and avoiding these areas. To add...

Understanding the interaction between tectonics, climatically-driven surficial processes, and bedrock erodibilityprovides insight into how landscape develops over space time. Although numerous active faults, lithologicand climatic variability control across Northern Thailand, influence of these factors on thespatial adjustment a dynamic is largely unknown. In study, we focus lower-order channel...

The Longmen Shan is the steepest topographic front at the India-Asia collision zone and the site of the Mw 7.9 Wenchuan earthquake. Here to explain the interseismic GPS velocities across the greater Longmen Shan region, we develop a boundary element model including earthquake cycle effects, topography, the westward dipping Beichuan Fault and a ∼20 km deep, shallowly dipping, detachment, inferre...

Microbialites can have complex morphologies that preserve clues to ancient microbial ecology. However, extracting and interpreting these clues is challenging due to both the complexity of microbial structures and the difficulties of connecting morphology to microbial processes. Fenestrate microbialites from the 2521±3 Ma Gamohaan Formation, South Africa, have intricate structures composed of th...

the chambers. (ii) A drop of the culture is placed on the grid and then withdrawn until the fluid level is just below the surface of the grid; if the surface is wet, the covering film will not stick properly. (iii) The floor of the chamber is formed by dipping the cover slip through a film which has been previously cast on glass and stripped off onto a water surface; casting, stripping, and dip...

Compressive and extensive horsetails are common structures on the lateral termination of brittle strike-slip faults, which forms within the shallow continental crust. Here we report another possibility, the lateral termination of a brittle strike-slip fault in a formation-parallel low-temperature ductile shear zone within sulphatic, gypsum-dominated evaporites. In the Southern Alps, over a dist...

[1] Using a hybrid MPI/OpenMP parallel finite element method for spontaneous rupture and seismic wave propagation simulations, we investigate features in rupture propagation, slip distribution, seismic radiation, and seafloor deformation of the 2011 Mw 9.0 Tohoku-Oki earthquake to gain physical insights into the event. With simplified shallow dipping (10 ) planar fault geometry, 1D velocity str...
