Wavelet maxima curves of surface latent heat flux anomalies associated with Indian earthquakes

Abstract

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 600 km. © 2005 Author(s). This work is licensed under a Creative Commons License.
