METHODS OF TSUNAMI DETECTION AND OF POST-TSUNAMI SURVEYS

Abstract

In our paper we describe some of the methods of the last 25 years which have been used extensively to examine and register tsunami traces - particularly by satellite imaging of coastal zones before and after a tsunami has struck, thus assessing quickly the extent of coastal inundation over large areas without the need of a site visit. Nearly all countries bordering oceans, seas and bodies of water have established digital systems of water level registration in the range of tsunami waves. In this article we describe methods of tsunami detection and runup measurements, some based on our own participation in post-tsunami surveys. Also, we discuss the possibility of using robotic systems to survey tsunami traces in hard-to- reach places.
