Synoptic detection of the short-term atmospheric precursors prior to a major earthquake in the Middle East, North Saravan M 7.8 earthquake, SE Iran

摘要: At the present study, we applied a synoptic prospect to analysis of short-term atmospheric precursors that occurred prior major earthquake. The North Saravan M 7.8 earthquake on April 16, 2013 was first recorded in Middle East for past 40 years. We compiled eight variables during March, April, and May by using NASA/Giovanni NOAA/NCEP data. According anomaly detection variables, determined sudden increasing anomalies surface-specific humidity, surface-latent heat flux, surface-wind velocity 8–9, 2013, 6–7 days After O3 NO2 anomalous records long-term pressure levels, observed abnormal cloud fractions generated due severe greenhouse effect violent low geopotential height. Based satellite observations as obtained from MODIS Meteosat data, exposed local-waved shape clouds circular pattern high scale, respectively. believed plays main role triggering chain increased variations, ascending air turbulence, circulation 1 week Over results, propose use continuous monitoring reactive gasses release, e.g., O3, CH4, NO2, SO2, etc. motive precursor precursor’s chain, possible earthquakes active fault region Makran subduction zone.
