Earthquake prediction activities and Damavand earthquake precursor test site in Iran

摘要: Iran has long been known as one of the most seismically active areas world, and it frequently suffers destructive catastrophic earthquakes that cause heavy loss human life widespread damage. The Alborz region in northern part is an EW trending mountain belt 100 km wide 600 long. range bounded by Talesh Mountains to west Kopet Dagh east consists several sedimentary volcanic layers Cambrian Eocene ages were deformed during late Cenozoic collision. Several faults affect central Alborz. main are North Tehran Mosha faults. fault major shown its strong historical seismicity clear morphological signature. Situated vicinity city, this 150-km-long N100° E represents important potential seismic source. For earthquake monitoring possible future prediction/precursory purposes, a test site established region. proximity capital with high population density, low frequency but magnitude occurrence, their events have considered criteria for selection. In addition, within site, there hot springs deep water wells can be used physico-chemical radon gas analysis precursory studies. present activities include magnetic measurements; application methodology identification seismogenic nodes M ≥ 6.0 developed International Institute Earthquake Prediction Theory Mathematical Geophysics, IIEPT RAS, Russian Academy Science, Moscow (IIEPTM feasibility study using dense network locations stations short-term prediction medium- large-size based on Markov extended self-similarity data. establishment ongoing, selected IASPEI evaluation report precursors installation (i) local consisting 25 short-period seismometers, (ii) GPS eight instruments 70 stations, (iii) four instruments, (iv) wells.
