Thermal structure and megathrust seismogenic potential of the Makran subduction zone

Geophysical Research Letters, 2013
The Makran subduction zone experienced a tsunamigenic Mw 8.1 earthquake in 1945 and recent, smaller earthquakes also suggest seismicity on the megathrust; however, its historical record is limited and hazard potential enigmatic.

Frictional controls on the seismogenic zone: Insights from the Apenninic basement, Central Italy [PDF]

Earth and Planetary Science Letters, 2022
Crustal seismicity is in general confined within the seismogenic layer, which is bounded at depth by processes related to the brittle-ductile transition (BDT) and in the shallow region by fault zone consolidation state and mineralogy.

Characterizing the seismogenic zone of a major plate boundary subduction thrust: Hikurangi Margin, New Zealand

Geochemistry, Geophysics, Geosystems, 2009
The Hikurangi subduction margin, New Zealand, has not experienced any significant (>Mw 7.2) subduction interface earthquakes since historical records began ∼170 years ago.

Seismogenic width of a fault zone

Doklady Earth Sciences, 2011
High-precision catalogues containing data on the spatial distribution of earthquake sources associated with several fault zones have been processed. The analysis shows a high degree of spatial localization of seismicity. Most of the events are observed in a narrow zone with a characteristic width of about 100 m. This value is a part of a percent of the

Characterization of Seismogenic Zones of Romania

Pure and Applied Geophysics, 2000
—Although the time and magnitude range covered by available seismological data is limited, several significant regional trends are outlined in the seismogenic zones of Romania. Vrancea region, which is by far the most seismically active area, has a persistent rate of occurrence of intermediate-depth earthquakes, clustered in a very confined focal ...

Seismogenic zoning of southeast Australia

Australian Journal of Earth Sciences, 1997
In the period from 1958 to 1996 the Australian National University seismological network has located more than 7600 earthquakes in southeastern Australia with a network concentrated between Canberra and Sydney. This catalogue of earthquakes provides a good database for the analysis of the temporal and spatial distribution of events in the region.

Transition of accretionary wedge structures around the up-dip limit of the seismogenic subduction zone

Earth and Planetary Science Letters, 2007
The Nankai accretionary prism is divided into three segments: outer and inner wedges and their transition zone. These wedges reflect different aspects of wedge taper, internal deformation, and basal plate boundary fault.

A Note on the Geometric Configuration of Seismogenic Zones

Seismological Research Letters, 1986
An empirical classification scheme, based upon a length to thickness ratio, is developed to describe the geometric configuration of seismogenic zones as planar, tabular, or volumnar. That scheme is applied to 33 recent, high-quality studies of seismicity patterns and aftershock studies in the contiguous United States, Alaska, Canada, Nicaragua ...

The seismogenic zone of subduction thrust faults

Island Arc, 1997
Abstract Subduction thrust faults generate earthquakes over a limited depth range. They are aseismic in their seaward updip portions and landward downdip of a critical point. The seaward shallow aseismic zone, commonly beneath accreted sediments, may be a consequence of unconsolidated sediments, especially stable‐sliding smectite clays.
