Abstract

The present paper reports the modification in refractivity prior to the Iran earthquake that had occurred on 16 April 2013 in Iran (28.10°N, 62.05°E). The reception of over horizon GPS signal from two GPS receivers Surat (21.16°N, 72.78°E) and Lucknow (26.91°N, 80.95°E) and results of atmospheric refractivity profile derived from Radio Occultation observations from COSMIC satellite obtained for epicenter region are presented in this paper. It is seen that atmospheric refractivity gets modified from 8 to 6 days prior to the earthquake at the epicenter.
