“…The Stable Cratonic Regions (SCR) of the intraplate cratonic environments also referred as stable cratonic cores (Fenton et al, 2006) are the areas where no large earthquake or abundant paleoearthquakes are evidenced similar to the area of the present study. In the SCR paleoearthquakes may cause minor tilting of fault bounded blocks, giving rise to geomorphic anomalies for which there are not likely depositional and erosional explanation (Schumm et al, 2000).…”

Abstract:The Jurassic to Quaternary succession of Jaisalmer region has formed horst and graben structures as a result of Neogene tectonic movements. The topography and long stretches of streams indicates influence of faults and regional lineaments. Deflections in the streams are due to faults present on either sides of the tilted blocks and the formations of flood plains adjoining the highlands can be attributed to horsts and grabens. Abrupt changes in the ground water levels in wells of the same hydrological formation are also inferred due to tilted blocks in the region.

“…From investigations of similar geological areas around the world, the expected maximum magnitude of a tectonic-origin seismic event in Gauteng could be in the order of 6.8 (Fenton et al, 2006). However, most seismic hazard models in South Africa, without taking the potential effects of acid mine water into consideration, estimate an expected maximum magnitude of 5.5 for the Gauteng region due to normal mining activities (Davies and Kijko, 2003).…”

“…However, strong devastating earthquakes in them also occur. Estimated probabilities of extreme events (M ≥ 7) for the sites recommended for radioactive waste disposal in the shields of ancient platforms, though uncertain, are very low (Fenton et al, 2006). The time of the existence of high-seismicity zones along the boundaries of tectonic plates and, hence, the low-seismicity regions located between these zones within the plates is hundreds of millions of years (geotectonic megacycles), which far exceeds the reasonable period of safety assessment for long-lived radioactive waste repositories.…”

We consider possible approaches to the long-term prediction for seismic hazard in relation to the practical need for the safety of geological disposal of long-lived radioactive waste. The required period of prediction significantly exceeds the one reflected in the set of maps of General Seismic Zoning of the territory of the Russian Federation (GSZ-97). The first geological repository in Russia is planned to be set up in the Nizhnii Kan granite massif in the Krasnoyarsk Krai. This region is an intraplate territory with a relatively high seismic activity. We summarize the analysis of the known empirical generalizations and theoretical principles underlying the seismic hazard prediction. Real seismic events constantly violate forward-looking statements even for relatively short periods of time. These and other arguments suggest that the hypothesis of stationarity of the seismic regime, which is the basis of long-term prediction today, has limited and uncertain applicability in time. Intraplate earthquake prediction is especially uncertain because of the uncertainty in the factor responsible for generating tectonic stresses in these regions. The short horizon of the prediction, based on statistical methods, can be attributed to the nonlinearity of seismic geodynamic processes. Fundamental laws of tectonic processes should be used as the scientific basis for long-term predictions for seismic hazard at the sites chosen for geological disposal of long-lived radioactive waste. These processes can be reflected in models for the migration of the seismically active boundaries of lithospheric plates and the occurrence of seismic activity in intraplate regions.
