It is well-known that the Gutenberg-Richter power law distribution has to be modified for large seismic moments, due to energy conservation and geometrical reasons. Several models have been proposed, either in terms of a second power law with a larger b-value beyond a cross-over magnitude, or based on a “hard” magnitude cutoff or a “soft” magnitude cut-off using an exponential taper. Since the ...

background : on december 26, 2003 an earthquake measuring 6.8 on the richter scale, shook the city of bam in the south east of iran and killed more than 40000 people and nearly 30000 were injured. this is an epidemiological study performed on the victims of bam earthquake to analyze different types of injuries of patients admitted in kerman hospitals. methods:  in a retrospective cross-sectiona...

an earthquake with magnitude ms = 6.5 on the richter scale occurred in december 26th, 2003 in bam region in southeastern part of iran. this study investigates the chemical variations of the groundwater resources in the effected region. for this purpose, 30 wells were selected and chemical compounds, in terms of cations (ca+2, mg+2, na+, k+); anions (hco3, so4, cl, no2), as well as ec, tds and p...

In Seppelt and Richter (2005) we presented and discussed the differences in numerical simulations obtained from different modelling tools applied to a predatoreprey test-system. Based on analytical findings of this highly non-linear Lotkae Volterra-type model, including capacity-limited growth of the prey and density-dependent predation success, we were able to demonstrate that resulting trajec...

Sungun Copper Mine is located in an area with a high level of seismic hazard. Most recently, the Ahar-Varzeqan earthquake with a magnitude of 6.2 on Richter scale occurred on August 11, 2012; at a distance about 40 kilometers away from the mine. Nevertheless, the seismic stability of the final pit wall has not been comprehensively reviewed. In this research, the southwestern wall of the final p...

This paper study the recent seismicity in Earthquake hazard zones in India. A large historical earthquake event catalog to cover the period of 1900-2018, the parameters date, time, latitude, longitude, depth and magnitude has been used to calculating frequency-magnitude distribution (b-value) of seismic hazard zones in India. To convert different magnitude scales into a single moment magnitude ...
