Maps showing Quaternary deposits and active fault traces, paleoseismic trenches, scarp diffusion analyses, and soil characteristics in displaced alluvial surfaces are combined with previous paleoseismic studies to examine the character of late Pleistocene earthquake recurrence and estimate the net extension rate across the interior of the Great Basin of the western United States at the latitude of ~39°N. The study area includes faults bounding the Desatoya, Toiyabe, Moni tor, Simpson Park, Toquima, Antelope, Fish Creek, Butte, Egan, and Schell Creek Ranges. The rate of earthquake recurrence is documented to be signifi cantly less than observed within the Walker Lane-Central Nevada seismic belt and along the Wasatch, which respectively defi ne the western and eastern bound aries of the interior of the Great Basin. Late Pleistocene extension across the interior of the Great Basin is calculated to equal ~1 mm/yr across the 450 km transect and is consistent with rates defi ned by recent geodetic studies. The agreement in extension rate estimates over different time scales indicates that tectonic deformation in the Great Basin has been characterized by relatively slow and consistent extension through the late Pleistocene to the present. The internal deformation of the Great Basin and the pattern of strain release may refl ect a broad transition zone from northwest-directed shear in the west to extension along the eastern edge of the Pacifi c-North American plate boundary.

[1] The relationship of strain accumulation to strain release over different timescales provides insight to the dynamics, structural development, and spatial and temporal pattern of earthquake recurrence in regions of active tectonics. The Great Basin physiographic province of the western United States is one of the Earth's broadest regions of ongoing continental extension, encompassing an area reaching $800 km in width between the Sierra Nevada to the west and Wasatch mountains to the east. We present observations arising from excavations, scarp profiling, optically stimulated luminescence, and radiocarbon dating to place limits on the late Pleistocene paleoseismic history of faults bounding eight ranges across the interior of the northern Great Basin, specifically, the Shawave, Hot Springs, Humboldt, Sonoma, Shoshone, Tuscarora, Dry Hills, and Pequop ranges. Combining the observations with similar previously published studies within and at the margins of the Great Basin yields a transect that extends eastward across the basin between the 40th and 41st parallels. The sum of observations provides a picture of the patterns and rates of earthquake recurrence over the region during the last $20-45 kyr that may be compared to patterns of contemporary seismicity and recently reported measures of strain accumulation across the area using GPS. The recurrence rate of large surface rupture paleoearthquakes along ranges at the margins of the Great Basin is systematically greater than observed along ranges in the interior. The pattern is similar to seismological and geodetic measurements that show levels of background seismicity and strain accumulation are also concentrated along the margins of the Great Basin. An east-west extension rate across the interior of the Great Basin on the order of 1/2 mm yr À1 (strain rate of $1 nstrain yr À1 ) over the last $20-45 kyr is estimated by summing the record of paleoseismic displacements across the 400 km breadth of the transect, as compared to $2 mm yr À1 of strain accumulation indicated by a recently reported analysis of a collinear GPS survey. The comparison is hindered by significant uncertainties coupled to the geologic rate estimate. The transect also crosses the northern limit of the central Nevada seismic belt. The central Nevada seismic belt is defined by a north-northeast trending alignment of historical surface rupture earthquakes, increased levels of background seismicity, and strain accumulation rates greater than observed elsewhere in the interior of the Great Basin. The reported recurrence rate of late Pleistocene surface rupture earthquakes within the central Nevada seismic belt is also generally greater than observed along our transect. The observations when taken together suggest that the characteristics of strain release observed historically within the central Nevada seismic belt have been operative over the latest Pleistocene and that the apparently greater rates of strain accumulation and release in the central Nevada seismic belt are diminished or less localiz...

“…The database structure (see the Supplement) was inspired by other databases developed in the world, such as the ones from the USA (QFAULT; Haller et al, 2004), New Zealand (NZAFD; Langridge et al, 2016), Japan (Active Fault Database of Japan; AIST, 2016), Italy (ITHACA; Michetti et al, 2000) and Iberia (QAFI; García-Mayordomo et al, 2012). The proposed map for metropolitan France is associated with a relational database describing the state of knowledge for each fault segment.…”

Abstract. The French Institute for Radiation Protection and Nuclear Safety (IRSN), with the support of the Ministry of Environment, compiled a database (BDFA) to define and characterize known potentially active faults of metropolitan France. The general structure of BDFA is presented in this paper. BDFA reports to date 136 faults and represents a first step toward the implementation of seismic source models that would be used for both deterministic and probabilistic seismic hazard calculations. A robustness index was introduced, highlighting that less than 15 % of the database is controlled by reasonably complete data sets. An example of transposing BDFA into a fault source model for PSHA (probabilistic seismic hazard analysis) calculation is presented for the Upper Rhine Graben (eastern France) and exploited in the companion paper (Chartier et al., 2017, hereafter Part 2) in order to illustrate ongoing challenges for probabilistic faultbased seismic hazard calculations.
