[1] The southwestern half of a 500 km long seismic gap in the central Kuril Island arc subduction zone experienced two great earthquakes with extensive preshock and aftershock sequences in late 2006 to early 2007. The nature of seismic coupling in the gap had been uncertain due to the limited historical record of prior large events and the presence of distinctive upper plate, trench and outer r...

The frontal thrust of the Oregon accretionary prism scrapes off about 2 km of incoming sedimentary section and underlies a fault-bend fold of the first ridge landward of the abyssal plain. Scarps with associated chemosynthetic biological communities at the surface and pore-water anomalies at depth indicate that the frontal thrust is tectonically and hydrologically active. At Site 891, near seis...

Turtle Mountain, the site of the 1903 the Frank Slide, has been widely studied. A large database of structural measurements allows the comparison and testing of recently developed techniques. This paper commences with a review of recent mapping of Turtle Mountain. A report on a recent investigation of the mountain using a combination of airborne and terrestrial laser scanning techniques is then...

[1] We document a new model of crustal structure of the Andean front in Argentina where numerous historic earthquakes destroyed the cities of Mendoza in 1861 (Ms = 7) and San Juan in 1944 (Mw = 7.0). The Cerro Salinas anticline is formed above the west directed Cerro Salinas thrust. An east facing monocline with an amplitude of about 2 km folds the Cerro Salinas thrust and overlying Neogene suc...

[1] The 8th October 2005 Kashmir Earthquake Mw 7.6 involved primarily thrust motion on a NE-dipping fault. Sub-pixel correlation of ENVISAT SAR images gives the location of the 80 km-long fault trace (within 300–800 m) and a 3D surface displacement field with a sub-metric accuracy covering the whole epicentral area. The slip distribution inverted using elastic dislocation models indicates that ...

S U M M A R Y The arrival pattern (AP) method and teleseismic data have been used to relocate aftershocks following three major (M w >= 7.8) interplate earthquakes that occurred in eastern Papua New Guinea in 2000 November. The first event was an M w = 8.0 strike-slip earthquake that ruptured the Weitin fault over a length of ∼100 km. No aftershocks were located in the upper 15 km, suggesting t...

We have investigated the possible cause-and-effect relationship due to stress transfer between two earthquakes that occurred near Christchurch, New Zealand, in September 2010 and in February 2011. The Mw 7.1 Darfield (Canterbury) event took place along a previously unrecognized fault. The Mw 6.3 Christchurch earthquake, generated by a thrust fault, occurred approximately five months later, 6 km...
