Preservation of amorphous ultrafine material: A proposed proxy for slip during recent earthquakes on active faults
The criteria for designating an "Active Fault" not only are important for understanding regional tectonics, but also are a paramount issue for assessing the earthquake risk of faults that are near important structures such as nuclear power plants. Here we propose a proxy, based on the preservation of amorphous ultrafine particles, to assess fault activity within the last millennium. X-ray diffr...
متن کاملinterseismic behavior of active faults estimation based on geodetic observation, the case study: north tehran fault
studying active faults behavior for earthquake prediction and recognition is a concentrated subject in earth science. precise measurements of earthsurface deformation by geodetic observation provide a good reference for studying different geodynamic phenomena. applying geodetic measurements in postseismic and interseismic intervals is an important tool for estimating strain accumulation and rh...
متن کاملDeeper penetration of large earthquakes on seismically quiescent faults.
Why many major strike-slip faults known to have had large earthquakes are silent in the interseismic period is a long-standing enigma. One would expect small earthquakes to occur at least at the bottom of the seismogenic zone, where deeper aseismic deformation concentrates loading. We suggest that the absence of such concentrated microseismicity indicates deep rupture past the seismogenic zone ...
متن کاملFDM simulation of earthquakes off western Kyushu, Japan, using a land–ocean unified 3D structure model
Seismic activity occurred off western Kyushu, Japan, at the northern end of the Okinawa Trough on May 6, 2016 (14:11 JST), 22 days after the onset of the 2016 Kumamoto earthquake sequence. The area is adjacent to the Beppu–Shimabara graben where the 2016 Kumamoto earthquake sequence occurred. In the area off western Kyushu, a M7.1 earthquake also occurred on November 14, 2015 (5:51 JST), and a ...
متن کاملHeterogeneous fault stresses from previous earthquakes and the effect on dynamics of parallel strike-slip faults
[1] We combine a viscoelastic model for the interseismic process and an elastodynamic model for the coseismic process to explore the dynamics (over multiple earthquake cycles) of two parallel strike-slip faults embedded in a two-dimensional full space. The step over fault geometry results in a buildup of heterogeneous fault stress near the step over. This heterogeneous stress accumulates at the...
