Understanding variability in the size and location of large earthquakes along subduction margins is crucial for evaluating seismic tsunami hazards. We present a coseismic slip model 2021 M8.2 Chignik earthquake investigate relationship this to previous major events Alaska Peninsula region interseismic coupling. Stress changes from 2020 M7.8 Simeonof event triggered event, together, partially filled an unruptured section 3000-km margin that has experienced series ruptures almost its entire...
Abstract On 23 June 2020, an Mw 7.4 earthquake struck offshore Oaxaca, Mexico, providing a unique opportunity to understand the seismogenic tectonics of Mexican subduction zone. In this study, near-field coseismic deformation caused by event was retrieved from Global Positioning System (GPS) observations and Interferometric Synthetic Aperture Radar (InSAR) measurements. Given static geodetic measurements, high-rate GPS waveforms, teleseismic fault geometry rupture process for 2020 Oaxaca...
Abstract Coulomb stress change is the in resultant force of shear and friction imposed on a receiver fault plane. The resulting often computed using 3.4 postseismic Green’s functions components (PSGRN-PSCMP) programs. Notwithstanding both preferences, have incomplete optimally oriented failure planes (OOPs) are inconvenient to resolve changes various placed varying depths. Here, we present an alternative program termed AutoCoulomb. It leverages shell command-line tool automatically...
SUMMARY A remarkable earthquake sequence struck the island of Lombok in Indonesia during period from 2018 July 28 to August 19. In this study, we use Sentinel-1 and ALOS-2 radar images investigate deformation related these events. The co-seismic surface was pre-dominated by uplift without rupture. It is worth noting that some rupture offshore. For thrust-dominated earthquakes, whether incomplete onshore obtained InSAR observation can well constrain geometry underground faults a question...
Abstract The Jinghe, Xinjiang, earthquake on 8 August 2017 is not only one of the largest events that happened along north Tien Shan but also first Mw>6 event received adequate seismic and geodetic observations in this region, providing a rare chance to gain insights into faults bound Shan. A previous rupture model (Zhang et al., 2020) was built based hypothesis north-dipping seismogenic fault, field geological mapping suggests fault be south dipping. Different geometry would result...
On 29 July 2021, an Mw 8.2 megathrust earthquake struck the Alaska Peninsula. Quantifying coseismic slip and afterslip that followed this provides us opportunity to clarify budget hazard potential there. However, estimated distribution inversion result is strongly affected by assumptions made in inversion. The spatial pattern of stress-driven mainly controlled distribution, so it can provide new information about useful assess orientation relative magnitudes postseismic displacements at...
The Pamir, situated in central Asia, is a result of the ongoing northward advance Indian continent, leading to compression Asian landmass. While geodetic and seismic data typically indicate that most significant deformation Pamir along its northern boundary, an Mw 7.2 earthquake on 7 December 2015 6.8 23 February 2023 have occurred remote interior Pamir. These two ≥ 6.5 earthquakes, with good observations satellite synthetic aperture radar data, provide rare opportunity gain insights into...
Abstract On 8 August 2017, an Ms 6.6 earthquake occurred in Xinjiang province, Northwest China. As no visible surface ruptures, coupled with the complex regional fault systems, seismogenic structure of is still unclear. Rich aftershock data can constrain to some extent, but only a handful aftershocks were recorded by China Earthquake Networks Center (CENC) this case. To augment CENC catalog, we first relocated and then adopted them as templates scan continuous waveforms five days before...
