A DETERMINATING METHOD OF AN ABRUPT MOTION OF THE SEA BOTTOM BY USING SNAPSHOT DATA OF WATER WAVES

摘要

PURPOSE: A submarine impact motion estimating method using the momentary measurement information of water waves is provided to measure a wave form change of the water surface caused by the sudden deformation of a sea-bed caused by earthquakes, landslides, and nuclear tests in a short time. CONSTITUTION: A submarine impact motion estimating method using the momentary measurement information of water waves is as follows. A wave form change of the water surface is measured by a measuring device. The deformation of a sea-bed is estimated by an analyzing device based on the measured wave form change of the water surface. The wave form change of the water surface is detected by snapshots of water surface photographed by a photographing device of a moving body such as an artificial satellite and an aircraft.
