“…10A), if the fault rupture coseismically acts (e.g., the Nankai out-of-sequence megasplay and other fault systems; see Planfker 1972; Tanioka and Satake 2001; Baba et al 2006;Kawamura et al 2009;Strasser et al 2009Strasser et al , 2011. Seismites are generally related to close seismic source areas subjected to a minimum magnitude of earthquake >5 (e.g., Atkinson 1984; see also Allen 1975Allen , 1986Youd 1978;Seed, 1979;Seed et al 1983;Obermeier et al 1993). Hence, the widespread occurrence of such structures over a broad area (hundreds to about thousands of kilometer square), characterized by the same geological setting, may suggest earthquake shaking of greater magnitude (e.g., Seed, 1968;Obermeier et al 1993;Moretti et al 1995;Perucca and Moreiras 2006), which worked in conjunction and cumulatively with generalized fluid flows, creating different weakness zones within the hanging wall of the out-of-sequence thrust (Fig.…”

(2015) -International GeologyThe definitive version is available at:La versione definitiva è disponibile alla URL:http://www.tandfonline.com/loi/tigr20 AbstractIn the Northern Apennines of Italy, mud-rich olistostromes (sedimentary mélanges) occur at different stratigraphic levels within late Oligocene -early Miocene sedimentary record of episutural/wedge-top basins. They are widely distributed along the exhumed outer part of the Ligurian accretionary complex, atop of the outer Apenninic prowedge, over an area of about 300 km long and 10-15 km wide. Olistostromes represent excellent examples of ancient submarine mass-transport complexes (MTCs), consisting of stacked cohesive debris flows that can be directly compared with some of those observed in modern accretionary wedges. We describe the internal arrangement of olistostrome occurrences in the sector between Voghera and the Monferrato, analyzing their relationships with mesoscale liquefaction features, which are commonly difficult to observe in modern MTCs. Slope failures occurred in isolated sectors along the wedge front, where out-of-sequence thrusting, seismicity and different pulses of overpressured tectonically-induced fluid flows acted concomitantly. Referring to the Northern Apennines regional geology, we also point out a gradual lateral rejuvenation (from late Oligocene to early Miocene) toward the SE and an increasing in size and thickness of the olistostromes along the strike of the frontal Apenninic prowedge. This suggests that morphological reshaping of the outer prowedge via mass transport processes balanced with different pulses in a short time span the SE-ward migration and segmentation of the accretionary processes. The latter have been probably favored by the occurrence in the northwestern part of the Northern Apennines of major, inherited paleogeographic features controlling the northward propagation of the prowedge. The detailed knowledge of olistostromes, as ancient examples of MTCs related to syn-sedimentary tectonics and shale diapirism, and of their lateral variations in term of age and size, provides useful information for better understanding both the tectono-stratigraphic evolution of the Apenninic prowedge and the submarine slope failures in modern accretionary wedges.

“…Statistical studies show that the number of cycle s representative of different magnitude earthquakes is typically as shown in Table 1. Furthermore a representati v e shape for the relationship between cyclic stress ratio an number of cycles required to cause liquefaction show s that the relative values of stress ratio required to caus e liquefaction in different numbers of cycles are typicall y close to those shown in the table (Seed et al, 1983) Thus by multiplying the boundary curve in fig. 3 by th e scaling factors shown in column (3) of Table 1, boundar y curves separating sites where liquefaction is likely to occu r or unlikely to occur may be determined for earthquake s with different magnitudes.…”

“…The results have been compiled in the U.S. over a 14 year period (1969-present) and the most recent compilation of this field data collection is shown in fig. 3 (after Seed, Idriss and Arango, 1983). Values of cyclic stress ratio known to be associated with some evidence of liquefaction or no liquefaction in the field are plotted as a function of the normalized penetration resistance Ml of the sand deposit involved.…”

“…The reports (SPT bore logs) are widely available for any city, as it widely used for calculation of bearing capacity for foundation design. Hence, the correlations exist between SPT-N and Vs30 in the literature to obtain the Vs profiles with depth (Imai & Tonouchi 1982;Seed et al 1983;Sisman 1995). In this study, Vs profiles were obtained through MASW tests at 27 locations in the Agartala city area and Vs30 estimated for these 27 locations.…”

The design response spectrum is smooth in shape compared to other response spectra. The objective of design spectra is to estimate the possible earthquake lateral loads which may experience on a particular structure during its design life. In this study, an attempt has been made to develop, design response spectra for the Agartala city, Tripura which is one of the North Eastern states in India considered at the highest level of seismic activity in the country having a zone factor 0.36g as per Indian seismic code (BIS 1893(BIS -2002. Based on the present data set collected from 1731-2011, the region is characterized and the seismicity parameters estimated separately for each source zone by Gutenberg and Richter (G-R) relationship. The two ground motion models were used for the hazard prediction. However, hazard curve, and uniform hazard response spectra (UHRS) (2% and 10% probability level for 50 years) has been developed for the Agartala at seismic bedrock level condition. Further, the NEHRP (National Earthquake Hazards Reduction Program) site classes D and E-types have been identified based on the average shear wave velocity at an upper 30 m depth of the subsurface soil profile. The direct shear wave velocity profiles were obtained through multi channel analysis of surface wave tests conducted at 27 locations at Agartala city. The design response spectra have been developed at the surface level for both the site classes. The results could be used as direct inputs for earthquake resistant design of civil engineering infrastructures of the study area.
