AB: Three Indian coastal earthquakes (Gujarat, Pondicherry and Andaman) have occurred near the western and eastern coasts of India. These earthquakes are known as intraplate earthquakes which occurred far from the plate boundaries. The physics of such earthquakes are still a mystery to the scientific community. These earthquakes at times have proved to be disastrous e.g. 20000 people were killed in the Gujarat earthquake of January 26, 2001. In the present paper, detailed analysis of remote sensing data has been carried out of various land, ocean and atmospheric parameters prior and after the earthquake. The IRS P4 OCM data have shown significant changes in chlorophyll concentration. The MODIS data from these earthquakes have shown significant changes of the land infrared thermal temperature. The surface latent heat flux retrieved from the NOAA satellites over the epicentral region of these earthquakes show anomalous increase prior to the main earthquake. Various parameters deduced from various satellites data have been analysed statistically and also using signal - noise decomposition of time series using the continuous wavelet transform. The detailed analysis of these parameters shows strong interaction between land-ocean-atmosphere prior to the earthquake. Such interaction shows anomalous behavior of land, ocean and atmospheric parameters that can be used in the early warning of impending coastal earthquakes.
