A number of seismic and other geophysical phenomena exhibit significant lateral heterogeneity along the strike Cascadia forearc. Both overriding downgoing plate have been invoked to play dominant role in controlling along-strike correlations between seismogenic behavior, potential field measurements, morphological/tectonic characteristics, structure; however, feedbacks likely exist two. In this...

Earthquakes occurring at the Pacific Rim can trigger tsunamis that propagate across the ocean and can produce significant damages far away from the source. In French Polynesia, the Marquesas Islands are the most exposed to the far-field tsunami hazards, since they are not protected by any outer coral reef and since submarine slopes are less steep than in other islands. Between 1994 and 1996, fo...

[1] Faulting and brittle deformation of mantle rocks occurs in many tectonic settings such as oceanic transform faults, oceanic detachment faults, subduction zones, and continental rifts. However, few data exist that directly explore the frictional properties of peridotite rocks. Improved constraints on the brittle deformation of peridotite is important for a more complete understanding of the ...

A sequence of earthquakes occurred on March 3rd and 4th in Northern Thessaly, northern Greece, associated with previously unknown, blind normal faults within the crystalline Palaeozoic basement Pelagonian geotectonic zone. Surficial ground deformation, such as liquefaction phenomena fluvial plains, well soil fissures rock falls, have been mapped. Geological indications unmapped seismic fault, i...

The well-established variation in the depth of earthquakes along both branches East African Rift System offers an opportunity to probe controls on depth-extent seismogenesis, and length-scales over which this may vary. We present updated compilation well-determined earthquake depths from teleseismic regional seismic data for System, combined with a summary distribution smaller-magnitude microse...
