one fault gouge smoothly cuts the microbreccia, while the other gouge is undulated and fragmented, indicating the recurrence of microbrecciation and shear localization along the thin gouge zones. On X-ray computed tomography (CT) images, the gouges...

2006). Hence, the spatial 3D b-value map prepared during present study for these three regions showed variation of the volcansim with depth and laterial variation of the low velocity zones respectivelly, which are confirmed by the high and the low b-values associated with occurance of Large ...
σ1–σ3) produced by fault/shear-zone interactions are of sufficient magnitude to drive changes in strain-rate in viscous shear zones, that in turn drive periods of rapid or slowed slip on overlying brittle faults
Stress drop is an earthquake property indicative for the characteristic relation of slip to fault dimension. It is furthermore affected by fault strength, fault topography, the presence of fluids, rupture size, slip, and velocity. In this article, the st
of the North Anatolian Fault. Liquefaction effects preserved in beds ofsandandpeathave provided evidence—when radiometric dating methods are used—for large paleoearthquakes extending back for more than 1,000 years in many seismically active zones, including thePacific Northwestcoastof theUnited States...
hope to pursue with the U.S. Geological Survey is to send waves of energy underground, such as through a hammer, and then see how they move through the earth. If a fault is there, the energy will move in a specific way, and studying it will help scientists better map the fault. ...

The region where the February 6, 2023,M7.5 earthquake sequence occurred is seismically active, although seismicity is moderate (<M7) compared to the nearby plate boundary zones in Turkey. The epicenter of this event places it on the Sürgü fault, directly west of the East Anatolian fault. ...
In addition, the terrain in this area is complex, located in the Longmenshan fault zone (one of the fault zones with the largest topographic gradient in the world), and there have been many strong earthquakes. By investigating the occurrence of geological hazards (e.g., landslides) in the ...
