Analysis of Tide-Gauge Records of the 2011 East Japan-off Pacific Coast Earthquake Tsunami

Abstract

The main goal of this paper is to analyze the tide-gauge records of the 2011 East Japan-off Pacific Coast Earthquake Tsunami. All tide gauge records are collected from UNESCO/IOC, Japan Meteorological Agency and Korea Hydrographic and Oceanographic Administration. These collected data filtered from the tidal component. They are used to re-determine observed tsunami characteristics (positive and negative amplitudes, heights, travel time). The results of given analysis are compared with the results of the direct numerical simulation of the tsunami wave propagation in the framework of the linear shallow-water theory using the GEBCO 30 arc second bathymetry.
