Abstract
  One of the most important issues in seismology is to accurately determine the epicenter of earthquake, mainly because the accuracy of dependent studies such as seismic risk analysis, fault mechanism, depends on the accuracy of mentioned parameter. Double difference method is one of the conventional relative ...  Read More

Volume 29, Issue 114 , December 2019, , Pages 35-40

https://doi.org/10.22071/gsj.2018.152368.1549

Abstract
  Hydraulic fracture is known as one of the effective methods for producing or being caused a change in the physical structure of a reservoir rock. In oil and gas reservoirs which have been fractured by a hydraulic approach, this method causes that a production well and the time of reservoir production ...  Read More
