Natural HazardsSummary: Destructive tsunamis are infrequent compared with other natural disasters, and their evidences tend to disappear quickly. Conventional data acquisition have been limited in coverage and tend to be unreliable. Readily available and transient data should be collected by field survey teams as soon as possible. Since tsunamis are always triggered by the simultaneous or in-advance occurrence of another phenomena, they can be considered close to the source as a syndrome, leaving a variety of almost simultaneous effects at the nearby coasts. By observating the evidence left by these local interaction effects, the surveyors should be able to identify and evaluate at least the maximum horizontal extension and the vertical reach of the inundation. High water marks and lines of landward limit of sea grass, debris or sediment deposited, may help in this identification and measurement process. Guidelines to conduct post-tsunami field surveys and standards for the observations have been established by the International Coordination Group for the Tsunami Warning System in the Pacific (ICG/ITSU) upon agreement with the scientific community. A Post-Tsunami Survey Field Guide was published by the Intergovernmental Oceanographic Commission (IOC) of UNESCO. - Reproduced
