A new plate model is used to analyze the mean seismicities of seven types of plate boundary (crb, continental rift boundary; ctf, continental transform fault; ccb, continental convergent boundary; osr, oceanic spreading ridge; otf, oceanic transform fault; ocb, oceanic convergent boundary; sub, subduction zone). We compare the platelike (nonorogen) regions of model PB2002 (Bird, 2003) with the centroid moment tensor (cmt) catalog to select apparent boundary half-widths and then assign 95% of… Expand
Seismic imaging of the structure of the central Ecuador convergent margin : relationship with the inter-seismic coupling variations
The structural interpretation of 2D-Pre-stack Depth Migrated Multichannel Seismic Reflection sections collected during the SISTEUR cruise across the Ecuadorian margin was combined with multibeamExpand
Exploratory models of long-term crustal flow and resulting seismicity across the Alpine-Aegean orogen
[1] Long-term crustal flow is computed with a kinematic finite element model based on iterated weighted least squares fits to data and prior constraints. Data include 773 fault traces, 106 faultExpand
Seismic Hazard Inferred from Tectonics: California
In this paper we propose simple methods for estimating long-term average seismicity of any region, based on a local kinematic model of surface velocities and an existing global calibration ofExpand
Earthquake Patterns in Diverse Tectonic Zones of the Globe
We extend existing branching models for earthquake occurrences by incorporating potentially important estimates of tectonic deformation and by allowing the parameters in the models to vary acrossExpand
Revised Tectonic Forecast of Global Shallow Seismicity Based on Version 2 . 1 of the Global Strain Rate Map by Peter Bird and Corné Kreemer
A major upgrade of the Global Strain Rate Map, version 2.1, uses far more geodetic data, systematic data processing, more modeled plates and plate boundaries, an improved algorithm, and a finerExpand
Geodetic evidence for low coupling on the Hellenic subduction plate interface
We develop a block model for the Aegean and surrounding areas, constrained by Global Positioning System (GPS), in order to investigate the degree of coupling on the Hellenic subduction interfaceExpand
Effects of the heterogeneous subducting plate on seismicity: Constraints from b-values in the Andaman–Sumatra–Java subduction zone
Abstract The Andaman–Sumatra–Java subduction zone is characterized by significant spatial variations in subducting plate age, subduction velocity, and slab bending. With (i) the uplifting controlledExpand
The tectonic crustal stress field and style of faulting along the Pacific North America Plate boundary in Southern California
We invert for the state of stress in the southern California crust using a catalogue of high quality earthquake focal mechanisms (1981–2010). The stress field is best resolved where seismicity ratesExpand
Long-term fault slip rates, distributed deformation rates, and forecast of seismicity in the western United States from joint fitting of community geologic, geodetic, and stress direction data sets
[1] The long-term average velocity field of the western United States is computed with a kinematic finite element code. Community data sets include fault traces, geologic offset rates, geodeticExpand
In this paper we present GPS observations of crustal deformation in the Africa-Arabia-Eurasia zone of plate interaction, and use these observations to constrain broad-scale tectonic processes withinExpand


Transform fault earthquakes in the North Atlantic: Source mechanisms and depth of faulting
We have determined the centroid depths and source mechanisms of 12 large earthquakes on transform faults of the northern Mid-Atlantic Ridge from an inversion of long-period body waveforms. TheExpand
Nature of seismic coupling along simple plate boundaries of the subduction type
The downdip width of the seismogenic zone is defined for 19 subduction zones. This width is measured from the base of the accretionary prism to the maximum depth of nucleation of thrust events alongExpand
