Growth of bending-moment faults due to progressive folding: Insights from sandbox models and paleoseismological implications
2019, GeomorphologyCitation Excerpt :Active anticlines are usually cut by many closely-spaced BMFs; in such settings microfaulting and fracturing is locally pervasive, allowing fluid and gas seepage from deeper reservoirs (e.g., Bonini, 2007). In the El Asnam thrust earthquake (ML 7.3; 10 Oct. 1980), a normal fault scarp on the anticlinal crest was the most prominent coseismic surface rupture, being mistaken as a primary fault itself (Yielding et al., 1981; Philip and Meghraoui, 1983). Development of similar bending-moment normal faulting, accompanying the 1978 Tabas-e-Golshan (Iran) earthquake, (MS 7.7; 16 Sept. 1978) is reported by Berberian (1979).
Growth and seismic hazard of the Montserrat anticline in the North Canterbury fold and thrust belt, South Island, New Zealand
2017, Journal of Structural GeologyCitation Excerpt :In fold and thrust belts around the world, many folds overlie blind thrust faults, which are capable of producing large magnitude earthquakes (King et al., 1988; Lin and Stein, 1989; Jackson et al., 1996). Numerous investigations confirm coseismic deformation from fault-related folds, including the 1982–1985 California earthquake sequence (Stein and King, 1984; Stein and Ekstrom, 1992), the 1980 El Asnam (Algeria) earthquake (Yielding et al., 1981), and the 1999 Chichi earthquake in Taiwan (Lin et al., 2007). The North Canterbury region on the South Island, New Zealand is an example of an actively growing fold and thrust belt where thrust faults, sometimes blind, underlie folds, presenting a potential seismic hazard.
The Al-Borani submarine landslide and associated tsunami. A modelling approach
2015, Marine GeologyDefining fault avoidance zones and associated geotechnical properties using MASW: A case study on the Springfield Fault, New Zealand
2014, Engineering GeologyCitation Excerpt :The challenge is increased because the internal structure of faults is not limited to a simple planar surface but incorporates a damage zone ranging up to hundreds of metres in extent, within which complex distributed deformation may take place. For example, well documented observations from surface rupturing earthquakes such as Algeria (King and Vita-finzi, 1981; Yielding et al., 1981; Ruegg et al., 1982; Philip and Meghraoui, 1983), Chi Chi (Kelson et al., 2001; Lee et al., 2006, 2010, 2011) and recently New Zealand (Van Dissen et al., 2011; Quigley et al., 2012; Duffy et al., 2013), demonstrate that folding, tilting and secondary faulting in a variety of configurations may extend well beyond the main rupture trace. Buildings sited across discrete surface ruptures invariably sustain the greatest rupture-related damage during an earthquake, followed by those buildings that lie within the zone of distributed deformation, in close proximity to the fault (Kelson et al., 2001; Van Dissen et al., 2011).
