In the northern part of Sumatra Island, Indonesia, Great Sumatran Fault, which can cause an earthquake, was divided into two segments: Aceh and Seulimeum. An effort to reduce risk is mapping fault area, especially in region that does not clearly show sign on surface, e.g., Lamtamot Indonesia. Electrical resistivity widely used study shallow structures, but method requires more time when applied...

We present the results of a paleoseismic survey Incapuquio Fault System, prominent transpressional fault system cutting forearc South Perú. High-resolution Digital Elevation Models, optical satellite imagery, radiocarbon dating, and trenching indicate that at least 2–3 m net slip occurred on generating complex, ∼100-km long set segmented scarps in early 15th century (∼1400–1440 CE). interpret c...

The Burdur Basin, which is located in the Lakes Region SW Anatolia, was formed by vertical faulting movements. erosion surfaces were developed on marl deposit accordance with lowering of base level each movement east Basin. These are at an elevation 980, 995, 1040, 1115, 1200, 1300-1340 m Neogene and knickpoints along valleys indicate six times depressed fault lines scarp extending Basin dissec...

Abstract Lobate scarps (thrust faults) in the lunar south polar region (90°–60°S) provide important insights into tectonic history, seismicity, and seismic hazard potential of landing sites. In this study, we discovered 75 new lobate >500 segments, exhibiting latitudinal variation geometry movement directions. Formation ages 141 prominent scarp segments show fault growth rates directions, de...

The Bilila-Mtakataka Fault (BMF), at the southern end of western branch East African Rift System (EARS), has been used in various scaling relation studies and arguments about strength lithosphere. We present evidence for a similar, though more degraded, frontal scarp on graben-bounding synthetic Chirobwe-Ntcheu (CNF), showing that this fault is active simultaneously with BMF. deployed 17 geopho...

Abstract. Seismic hazard assessment in slow straining regions is challenging because earthquake catalogues only record events from approximately the last 100 years, whereas recurrence times on individual faults can exceed 1000 years. Systematic mapping of active allows fault sources to be used within probabilistic seismic assessment, which overcomes problems short-term records. We use Shuttle R...

The 20 May 2016 MW 6.1 Petermann earthquake in central Australia generated a 21 km surface rupture with 0.1 to 1 m vertical displacements across low-relief landscape. No paleo-scarps or potentially analogous topographic features are evident pre-earthquake Worldview-1 and Worldview-2 satellite data. Two excavations the expose near-surface fault geometry mixed aeolian-sheetwash sediment faulted o...

SUMMARY This study explores the geomorphological expression and geological context of a normal fault scarp in stable continental region (SCR) which we interpret as having failed large (Mw >7) earthquakes. Records such faulting events an SCR (or even more rapidly deforming regions) are extremely rare, so understanding this feature is international interest. The exceptionally well-preserve...
