Description
Summary:The present study describes a prototype we built and named REMOTE for detecting and monitoring in real time tsunami events, based on changes in infrared radiation emitted from the sea when up thrust crustal movements from a major or a great tsunamigenic earthquake disturb the ocean floor and change the thermal properties of the water column in the source region. Specifically, we describe the hardware and software components of this system and present its performance results from recent tsunamis. Declouding of satellite images is often required and this is accomplished by the application of wavelet analysis. Also, in the present study we address the problem of signal delay due to the satellite scanning cycle and discuss possible solutions. Finally, we enumerate the relative benefits of our system. Our proposed system is available to all the countries with access to a geostationary weather satellite.
