Abstract We image the Zhaotong-Ludian fault (ZLF) in southeastern margin of Tibetan plateau (SE plateau) using waveforms from local and teleseismic earthquakes recorded by 14 seismic stations. identify two types zone head wave (FZHW) clusters applying an automatic picking algorithm a horizontal particle motion analysis. The first type FZHWs shows linear time–distance moveout is only observed at...

Abstract Renun Segment is located in the center of Sumatran Fault, parallel to Famous Toba Lake Volcano. The fault cuts thick, and vast Young Tuffs (YTT) deposited ∼74,000 years ago during supervolcano eruptions. It shows a series noticeable dextral strike-slip offsets river valleys that deeply incised tuffs. Our study will determine geological slip rate this location by measuring river-valley ...

We combine Global Positioning System and Interferometric Synthetic Aperture Radar (InSAR) data to characterize the interseismic behavior (i.e., locked or creeping), strain partitioning for faults along Caribbean-South American transform plate boundary. Interseismic is distributed mainly on three faults, San Sebastian, El Pilar, Central Range but occurs across multiple in west (San Sebastian La ...

current research in order to identify neo tectonic activity of the ziyarat basin has been made on the northern slopes of the eastern alborz in south-gorgan and using the index of morpho tectonic and tectonic evidence in the area. in this regard, the 6 morphological parameters were calculated and the results are analyzed. the overall results of these features, as indicators of the relative activ...

Based on the observation of geochemical characteristics 19 hot springs in Litang Fault Zone (LFZ) from 2010 to 2019, major elements, trace and stable isotopes were investigated, a conceptual model ground fluid circulation LFZ was established. The main hydrochemical type spring water samples is HCO3−-Na+. δ2H values range −157.6‰ −123.4‰ δ18O −24.5‰ −15.4‰. fault zone mainly recharged by infiltr...

considering recent developments in earthquake engineering, researchers has detected different effects of earthquakes far and near from the fault. investigations that have been done in this area show that near fault earthquakes have shorter time period comparing far fault earthquakes and in the velocity of near fault earthquakes, there are one or more impacting pulses with a big domain and perio...

[1] We derived a coseismic slip model for the Mw 7.9 2008 Wenchuan earthquake on the basis of radar line‐of‐sight displacements from ALOS interferograms, GPS vectors, and geological field data. Available interferometric synthetic aperture radar (InSAR) data provided a nearly complete coverage of the surface deformation along both ascending (fine beam mode) and descending orbits (ScanSAR to Scan...

Earthquake hazard assessments and rupture forecasts are based on the potential length of seismic rupture and whether or not slip is arrested at fault segment boundaries. Such forecasts do not generally consider that one earthquake can trigger a second large event, near-instantaneously, at distances greater than a few kilometres. Here we present a geodetic and seismological analysis of a magnitu...
