IOP Conference Series: Earth and Environmental Science, 2021 Abstract in order to study the influence of ground fissures on the construction of expressway, a ground fissure (F1) with a strike of NE20∼45° and length of 120km in Yunnan Province is selected as the research object. The FLAC3D numerical software is used to study the characteristics of displacement and stress. The results show that: (1)

Recent Crustal Deformation in West-Central South America [PDF]
, 2003 I use interferometric synthetic aperture radar (InSAR) to create maps of crustal deformation along the coast and within the volcanic arc of central South America. I image deformation associated with six subduction zone earthquakes, four volcanic centers,

Measuring and Modeling Viscoelastic Relaxation of the Lithosphere with Application to the Northern Volcanic Zone, Iceland [PDF]
, 2010 Viscoelastic relaxation of the stress perturbation caused by an earthquake or diking event can produce measurable ground deformation over 100 km away from the source. We consider the role of viscoelastic relaxation in two different contexts.
