Tabas mines in Iran have coal sources which are suitable for use in metallurgy industries as coking coal. But the high sulfur content of this coal imposes severe limitations on its utilization as the sulfur oxide gases evolved from the combustion of high sulfur coals result in acid rains and corrosion of equipments. In this work, attempts have been made to reduce sulfur from high sulfur coa...

Introduction: Quaternary basalts are one of the last signs of magmatism in Iran, some of which are related to deep fractures and active faults in the Quaternary. Quaternary basalts of Tabas are very important due to their high expansion and location in eastern Iran, and are located 140 km south east of Tabas city and according to the proposed divisions are part of the Lut zone. The aim of this...

This paper introduces the application of seismic wave method in earthquake prediction and early estimation. The advantages of the seismic wave method over the traditional earthquake prediction method are demonstrated. An example is presented in this study to show the accuracy and efficiency of using the seismic wave method in predicting a medium-sized earthquake swarm occurred in Wencheng, Zhej...

rhaetian strata from the nayband formation of the tabas block, east- central iran, were studied palynologically. the materialexamined contained moderately diverse and well-preserved dinoflagellate cyst assemblages which lead to the identification ofrhaetogonyaulax rhaetica zone. the assigned age of this dinozone (rhaetian) is justified by plant fossils such as equisetitesarenaceus, scytophyllum...

Research concerning the impact of earthquake victims' individual behavior and its association with earthquake-related injuries is lacking. This study examined this relationship along with effectiveness of earthquake rescue measures. The six most severely destroyed townships during the Lushan earthquake were examined; 28 villages and three earthquake victims' settlement camp areas were selected ...

Physical modeling of earthquake generation processes is essential to further our understanding of seismic hazard. However, the scale-dependent nature of earthquake rupture processes is further complicated by the heterogeneous nature of the crust. Despite significant advances in the understanding of earthquake generation processes, and the derivation of underlying physical laws, controversy rema...

According to the features and demands of earthquake rescue on-site, automatic modelling and scene generation methods based on fundamental geographic data were investigated, and an earthquake scene model was proposed considering both effect of local site conditions on ground motion and vulnerability of different buildings. Based on ArcGIS Engine, the system in which the scene of pre-earthquake a...
