Active tectonics and earthquake potential of the Myanmar region [PDF]
, 2014 This paper describes geomorphologic evidence for the principal neotectonic features of Myanmar and its immediate surroundings. We combine this evidence with published structural, geodetic, and seismic data to present an overview of the active tectonic ...

Geophysical Research Letters, 2012 On February 27th 2010, a MW8.8 earthquake struck the coast of south‐central Chile, rupturing ∼500 km along the subduction interface. Here we estimate the amount of seismically‐released afterslip (SRA) and the mechanisms underlying the distribution of ...

Future Cascadia megathrust rupture delineated by episodic tremor and slip [PDF]
, 2009 A suite of 15 episodic tremor and slip events imaged between 1997 and 2008 along the northern Cascadia subduction zone suggests future coseismic rupture will extend to 25 km depth, or approximately 60 km inland of the Pacific coast, rather than stopping ...

Impact of Upper‐Plate Faulting on Megathrust Foreshocks: Insights From the 2014 Iquique Earthquake
Geophysical Research LettersThe role of upper‐plate faulting in the seismic cycle of large megathrust earthquakes remains poorly understood. We use quasi‐dynamic numerical simulations of seismic cycles to analyze the interaction between crustal faulting and the foreshock sequence ...

SeismicaOn October 19, 2020, the Mw7.6 Sand Point earthquake struck south of the Shumagin Islands in Alaska. Moment tensors indicate the earthquake was primarily strike-slip, yet the event produced an enigmatic tsunami that was larger and more widespread than ...

Do Coupled Megathrusts Rupture?
Megathrust earthquakes are among the most destructive and least predictable natural hazards. Kinematic geodetic coupling models, which identify regions of the plate interface where interseismic strain accumulates, are essential for seismic and tsunami hazard assessment.

Importance of forearc topography for the triggering of aftershocks of megathrust earthquakes: insights from mechanical models and the Tohoku-Oki and Maule earthquakes [PDF]
Solid EarthAftershocks of megathrust earthquakes at subduction zones may be driven by stresses arising from the topography of the forearc. However, the effect of topographic stresses on aftershock triggering is quantitatively not well understood and has been ...

Hypocenter estimation for 14 earthquakes in south-central Alaska (1929-1975) [PDF]
, 2018 We provide results from an analysis of 14 historical earthquakes in the region of Cook Inlet and Susitna, south-central Alaska. Using global arrival times of P and S waves, we estimate probabilistic hypocenters using the code NonLinLoc.
