“…51 In this report, many risk factors were identified, with earthquakes considered to be the most hazardous factor because the Himalayas are still tectonically active. 46,52 The data published in this report showed that since 1809 AD, Himachal Pradesh has experienced more than 80 earthquakes measuring !4 on the Richter scale . The most noticeable earthquakes were in the districts of Kangra (1905, magnitude 7.8) and Kinnaur (1975, magnitude 6.8), which claimed 20,000 and 60 lives, respectively.…”

Forensic anthropologists are not only active in courtroom testimonies but also contribute to disaster victim identification. The timely recovery and identification of victims in any disaster is crucial, and anthropologists play a vital role in this process. In mass disasters such as airplane crashes, tsunamis, earthquakes or terrorist attacks, fragments of dead bodies are usually brought for identification. Each fragment demands special tactics to fulfil any of the basic attributes of forensic identification such as age, sex, stature or ancestry. If sex and stature can be estimated from a single fragment, then it can potentially reduce the identification time and possible victim matches. In this study, an attempt has been made to estimate sex and stature from the second- and fourth-digit lengths. Different predictive and accuracy models have been devised using statistical techniques. No bilateral difference was observed in the digit lengths in either sex. Consequently, an average of the digit lengths was employed for model approximations. The fourth-digit length provided the best sex estimates (M=82.1%, F=79.2%) when binary logistic regression (BLR) statistics were applied. It was also observed that overall sex estimations improved from 78.8% (from BLR) to 79.8% when discriminant function analysis was used for sex estimation. Second- and fourth-digit lengths were used independently and together for stature estimation models for males and females individually and for the pooled sample. In stature estimation models, three major interpretations were perceived: (1) the second-digit length provided the best stature estimates; (2) the estimation models compute better stature estimates for females than their counterparts, that is, standard errors are less in females than males; and (3) second and fourth digits predict more reliable stature estimation when the sex of the digits is known than that of the pooled sample.

“…Geomorphologists Singh & Tandon 2010) have not commented on whether they are all out-of-sequence thrusts, presumably because absolute dates are unavailable. Around 2 m displacement was reported for the Pinjaur Garden Fault (review, Verma & Bansal 2014). Malik et al (2007b) identified two strands of the Pinjaur Garden Fault, F1 and F2, which they speculated might merge at a shallow depth.…”

“…Hence earthquakes are generally less likely to occur than near plate boundaries, as in the foothills of the mighty Himalayas. There are 30 neotectonic faults in stable PI, mostly limited to paleorift systems (Verma and Bansal 2016). It is to be noted that the information on the fault-plane geometry, mechanism (strike-slip, normal, oblique, thrust or subduction), extension, and activity rates is inadequate in order to adopt these faults within a PSHA framework.…”

“…It is to be noted that the information on the fault-plane geometry, mechanism (strike-slip, normal, oblique, thrust or subduction), extension, and activity rates is inadequate in order to adopt these faults within a PSHA framework. Paleoseismological studies constrained the recurrence intervals of the earthquake in the stable continental regions such as PI to 10,000 years (Verma and Bansal 2016). The control region considered for the present study includes a circular area of 300 km radius considering Gol Gumbaz, Vijayapura as its centre.…”

Probabilistic seismic hazard analysis (PSHA) is carried out for the archaeological site of Vijayapura in south India in order to obtain hazard consistent seismic input ground-motions for seismic risk assessment and design of seismic protection measures for monuments, where warranted. For this purpose the standard Cornell-McGuire approach, based on seismogenic zones with uniformly distributed seismicity is employed. The main features of this study are the usage of an updated and unified seismic catalogue based on moment magnitude, new seismogenic source models and recent ground motion prediction equations (GMPEs) in logic tree framework. Seismic hazard at the site is evaluated for level and rock site condition with 10% and 2% probabilities of exceedance in 50 years, and the corresponding peak ground accelerations (PGAs) are 0.074 and 0.142 g, respectively. In addition, the uniform hazard spectra (UHS) of the site are compared to the Indian code-defined spectrum. Comparisons are also made with results from National Disaster Management Authority (NDMA 2010), in terms of PGA and pseudo spectral accelerations (PSAs) at T = 0.2, 0.5, 1.0 and 1.25 s for 475-and 2475-yr return periods. Results of the present study are in good agreement with the PGA calculated from isoseismal map of the Killari earthquake, M w = 6.4 (1993). Disaggregation of PSHA results for the PGA and spectral acceleration (S a) at 0.5 s, displays the controlling scenario earthquake for the study region as low to moderate magnitude with the source being at a short distance from the study site. Deterministic seismic hazard (DSHA) is also carried out by taking into account three scenario earthquakes. The UHS corresponding to 475-yr return period (RP) is used to define the target spectrum and accordingly, the spectrum-compatible natural accelerograms are selected from the suite of recorded accelerograms.
