Audio-Visual and Hydroacoustic Observations of the Dead Sea Calibration Experiment

摘要

Three chemical charges of 500, 2060 and 5000 kg were detonated in November, 1999 in the Dead Sea at water depth of about 70 m (480 m below the ocean level). The main objective of the experiment was to calibrate the seismic travel times at local and regional distances. Using a specially designed recording system and GPS measurements, it was possible to provide an accuracy of 5 milliseconds for the detonation time and few meters for the location. However, the actual location accuracy was reduced to 50 meters due to strong variable undercurrents and winds in the Dead Sea.
