Satellites, tsunamis, and early warnings



In the early morning of 26 December 2004 the ocean research satellite Jason flew over the Indian Ocean and recorded a surface tsunami wave less than 1 meter high. If it was no more than chance that a satellite equipped with a sensitive radar passed over at that precise moment, then the potential role of orbiting spacecraft in future early warning systems was established.

This special tsunami workshop was convened during the PORSEC biennial symposium to review the performance of satellites and consider the extent to which future space systems could contribute to reducing the impact of marine hazards.
