Email:*linbfrank@gmail.com # wzhu@umes.edu Abstract: We describe a satellite based tsunami early detection system called REMOTE. Its response time is typically 2 minutes for all tsunamis. There will be no false positives and false negatives. It is inexpensive to install and can be made available to all coastal countries threatened by tsunamis. Keyword—Tsunami Early Warning, Tsunami Signal, Remote Sensing, Cloud, Tsunami Radiation I. INTRODUCTION In previous communications 1,2,3,4 we have reported the detection of tsunami radiation in the infrared domain for the submarine earthquakes of the Great Sumatra Tsunami of 2004 and the Tohoku tsunami of 2011. We have introduced the Signal Diagram and the Wavelet Diagram as representations of tsunamis in infrared space, and demonstrated the occurrence of tsunamis upon their births. We have also shown that these diagrams, as well as the vector representation of tsunamis, can be mapped into each other by a linear transformation. In this report we shall describe a system to detect the births of tsunamis based on the above findings, which has the advantage that its response time is almost instantaneous; it does not give false positive or false negative warnings; it is very inexpensive to implement and it can be made available to every country threatened by this natural calamity. *Corresponding author.

METHODS AND DATA We propose a satellite based Tsunami Early Warning System, called ‘REMOTE’, with the following components: PMEL ↓ SatelliteÆ Antenna Æ Receiver Æ Computer Æ Visualization ÆMonitoringÆAlarm In this scheme, the tsunami signal from the satellite is captured by the antenna and inputted into the receiver, which processes the signal and the resulting satellite image is scanned into the computer, which is generally a PC. At the same time, a real time warning with the location and time of a submarine earthquake is received from the PMEL or another watchdog. If the earthquake magnitude is greater than six on the Richter scale, a visualization of the signal is carried out and if the presence of a tsunami signal and the accompanying wavelet signal is found, a tsunami warning is immediately issued. This system is a significant improvement to the DART system in use today. The main advantages of the new system are: a. Time Delay For the DART System, the earthquake is registered by an underwater pressure gauge, which forwards this information acoustically to a buoy at the surface of the ocean. Since the signal travels at the speed of sound over hundreds of kilometers, a time lapse is incurred. This time lapse is critical for the effectiveness of
