Fully nonlinear inversion of fundamental mode surface waves for a global crustal model [PDF]
, 2007 We use neural networks to find 1-dimensional marginal probability density functions (pdfs) of global crustal parameters. The information content of the full posterior and prior pdfs can quantify the extent to which a parameter is constrained by the data.

Deformation and exhumation in thick continental crusts induced by valley incision of elevated plateaux [PDF]
Solid EarthSurface processes such as erosion and sedimentation play a critical role in crustal deformation, particularly in actively deforming orogenic belts. While these processes have been extensively studied in large-scale erosive and tectonically active regions,

Qinghai-Tibet Plateau crustal thickness derived from EGM2008 and CRSUT2.0
Geodesy and Geodynamics, 2014 Qinghai-Tibet Plateau is the most complex region for crustal thickness inversion, while high-resolution earth gravity model (EGM) makes it possible to obtain high precision gravity anomaly, which is a key parameter to depict the Earth’s inner structure ...

Efficacy of crustal superfluid neutrons in pulsar glitch models [PDF]
, 2015 In order to assess the ability of purely crust-driven glitch models to match the observed glitch activity in the Vela pulsar, we conduct a systematic analysis of the dependence of the fractional moment of inertia of the inner crustal neutrons on the ...

Cenozoic evolution of the eastern Black Sea: a test of depth-dependent stretching models [PDF]
, 2008 Subsidence analysis of the eastern Black Sea basin suggests that the stratigraphy of this deep, extensional basin can be explained by a predominantly pure-shear stretching history.

Crustal thickness beneath Rio de Janeiro, Brazil, from spectra of SH waves at station RDJ [PDF]
Geofísica Internacional, 2006 Amplitude and phase spectra of long period analog S wave records were used to estimate crustal thickness under Rio de Janeiro seismic station. Earthquakes with shallow focal depths (10-33 km) and epicentral distances varying from 83 to 88 degrees ...

Subparallel thrust and normal faulting in Albania and the roles of gravitational potential energy and rheology contrasts in mountain belts [PDF]
, 2009 The active tectonics of Albania and surrounding regions, on the eastern margin of the Adriatic Sea, is characterized by subparallel thrust and normal faulting which, we suggest, is likely to be related to gravitational potential energy contrasts between ...

Satellite magnetic anomalies of the Antarctic crust
Annals of Geophysics, 2000 Spatially and temporally static crustal magnetic anomalies are contaminated by static core field effects above spherical harmonic degree 12 and dynamic, large-amplitude external fields.

Global crustal thickness from neural network inversion of surface wave data [PDF]
, 2007 We present a neural network approach to invert surface wave data for a global model of crustal thickness with corresponding uncertainties. We model the a posteriori probability distribution of Moho depth as a mixture of Gaussians and let the various ...
