Outgoing Longwave Radiations as Pre-Earthquake Signals: Preliminary Results of 24 September 2013 (M 7.7) Earthquake

Outgoing longwave radiation (OLR) measurement, a satellite-based measurement can be used as a tool to identify the earthquake preparation process. OLR anomaly normally appears 1 to 30 days before the occurrence of earthquakes as revealed by analysis of previous earthquakes like the 2010 Haiti and 2011 Tohoku earthquakes. This communication presents the preliminary analysis of OLR anomaly prior to the recent 24 September 2013 (M 7.7) earthquake which occurred 63 km NNE of Awaran, Pakistan. The results show encouraging signs and forecasting of earthquakes is likely to be no longer 'elusive'.
