Cervone R. P. Singh M. Kafatos C. Yu Center for Earth Observing and Space Research, School of Computational Sciences, George Mason University, Fairfax, VA 22039, USA Department of Civil Engineering, Indian Institute of Technology, Kanpur 208 016, India Wavelet maxima curves of surface latent heat flux (SLHF) have been recently used to provide early warning information about coastal earthquakes. The present paper reports further validations of the spatial and temporal analysis of wavelet maxima curves associated with earthquakes occurred in different parts of the Indian sub-continent. Prominent anomalies that exhibit spatial and temporal continuity are found in case of coastal earthquakes, while no anomaly is detected in case of intraplate earthquakes. The precursory SLHF anomalies are found up to 2 weeks prior to the main earthquake event, with an extent area of up to 600km.
