!%" The Vogar Fissure Swarm is one of four en-echelon fracture swarms that connect the !&" Reykjanes Ridge to the South Iceland Seismic Zone and the Western Volcanic Zone. !'" Occurring in an area of flat topography, this fissure swarm is clearly visible at the surface, !(" where it can be seen to affect recent postglacial lavas. Using remote sensing methods to !)" identify and measure all the ...

The 2021 Mw 7.3 Maduo earthquake revealed the significant seismic hazard of faults developed within Bayan Har Block eastern Tibet, China (e.g., Kunlun Pass–Jiangcuo Fault). Relocated aftershock data are in good agreement with Interferometric Synthetic Aperture Radar (InSAR) coseismic displacement field and investigations. In this study, we used point cloud fitting to model relocated aftershocks...

Earthquake-related fault slip in the upper hundreds of meters of Earth's surface has remained largely unstudied because of challenges measuring deformation in the near field of a fault rupture. We analyze centimeter-scale accuracy mobile laser scanning (MLS) data of deformed vine rows within ±300 m of the principal surface expression of the M (magnitude) 6.0 2014 South Napa earthquake. Rather t...

[1] We estimate the current slip rates on active conjugate strike-slip faults in central Tibet using repeat-pass synthetic aperture radar interferometry (InSAR). The conjugate fault systems are centered along the east trending Late Jurassic–Early Cretaceous Bangong-Nujiang suture zone and are composed of NE striking left-slip faults to the north and NW striking right-slip faults to the south. T...

The 2016 Kumamoto earthquake (Mw 7.0) occurred in the central part of Kyushu Island, southwestern Japan, on April 16, 2016. The mainshock triggered an event of maximum acceleration 700 gal that caused severe damage to infrastructure and thousands of homes. We investigate the source location of the triggered event, and the timing of large energy release, by employing the back-projection method f...

High-resolution magnetotelluric (MT) studies of the San Andreas fault (SAF) near Hollister, CA have imaged a zone of high fluid content flanking the San Andreas fault and extending to midcrustal depths. This zone, extending northeastward to the Calaveras fault, is imaged as several focused regions of high conductivity, believed to be the expression of tectonically bound fluid pockets separated ...
