Exploring the relationship between InSAR coseismic deformation and earthquake-damaged buildings
Remote Sensing of Environment, 2021Abstract Strong ground vibration triggered by seismic waves is one of the most significant factors that causes building damage during a seismic event. The interferometric synthetic aperture radar (InSAR) technique can efficiently and quickly provide seismic deformation information.

Large Deformation Analysis of Coseismic Landslide Using Material Point Method
2021Realistic prediction of seismic landslides is critical for performance-based design in the seismically active regions. To date, analytical methods for estimating seismic landslides have been based on simplified models. Many gaps still remain in the scientific understanding of earthquake-induced landslides, especially the landslide triggering process ...

Defining the Coseismic Phase of the Crustal Deformation Cycle With Seismogeodesy
Journal of Geophysical Research: Solid Earth, 2021AbstractEarth's crustal deformation cycle is traditionally divided into coseismic, postseismic, and interseismic phases upon which transient motions from various sources may be superimposed. Here we present a new seismogeodetic methodology to define and identify the transition from the coseismic to the early postseismic phase.

Material point method for large deformation analyses of coseismic landslides
2023Estimation of coseismic landslides is of particular importance for seismic hazards assessment and mitigation strategies. To realitically and efficiently simulate the complete landslide process during earthquake from triggering to post-failure large movements, a robust computational tool is necessary.

Measurements of coseismic deformation in southern California: 1972–1982
Journal of Geophysical Research: Solid Earth, 1988Since 1972, a number of static strain changes have been measured at Piñon Flat Observatory, southern California, as a result of regional faulting. As recorded by a collection of long‐baselength strainmeters and tiltmeters, these signals are in good quantitative agreement with the deformation calculated for a dislocation in an elastic half‐space.

25-Second Determination of 2019 Mw 7.1 Ridgecrest Earthquake Coseismic Deformation
Bulletin of the Seismological Society of America, 2020ABSTRACT We have developed a global earthquake monitoring system based on low-latency measurements from more than 1000 existing Global Navigational Satellite System (GNSS) receivers, of which nine captured the 2019 Mw 6.4 Ridgecrest, California, foreshock and Mw 7.1 mainshock earthquakes.

Interpreting coseismic deformation using Holocene coastal deposits, Wellington, New Zealand
Quaternary International, 1995Abstract Eight Holocene palaeoshorelines (PS1–PS8) are recognised on Miramar Peninsula and Rongotai Isthmus, Wellington, New Zealand. Coseismic uplift (CU1) of PS1, by 1.35–1.50 m, occurred in 1855 associated with a magnitude 8.1–8.2 earthquake centred on the Wairarapa Fault, some 20 km east of the study area. The other palaeoshorelines (PS2–PS8) are

Morphological evidence of Holocene coseismic deformation in the Taormina region (NE Sicily)
Journal of Geodynamics, 2003In southern Italy, strongly uplifted coastal regions are located along the footwall of the main seismogenic fault segments which affect the Tyrrhenian side of southern Calabria and the Ionian coast of eastern Sicily. This morphotectonic picture is generally associated with high-level historical seismicity.

3D Green's functions for coseismic and postseismic deformation
2018Finite fault slip inversions are constrained by observational data of surface displacement and Green's functions calculated via a forward model of surface deformation. Although observational techniques in space geodesy have improved greatly in recent years, models of earthquake deformation generally do not include realistic Earth structure. Many finite
