Workflow of Tsunami Inversion Apr 13, 2015

Workflow and Data for Tsunami Inversion Make unit source create initial surface data (ini_surface.dat) by COMCOT. Input inversion area map then split it to unit source and make 1 meter water height to each unit source. Choose inversion area Decompose into Unit Sources Run COMCOT for each unit source Input: *bathymetry.xyz (bathymetry data) *comcot.ctl (control file) *ini_surface.dat (initial water surface data, 1 meter for each unit source) *ts_location.dat (tidal station location, at least one, three is better) Get initial water surface Input 1obs. data, tidal station records with time serial and 2COMCOT result, time serial records. Then use least square and smoothing method to get inverse initial water surface.

If Observed Time Series Data Is Missing, Only One Max Wave Height Could be Found Estimate the possible epicenter. Creating time serial record of water surface height by max water height. Do tsunami inversion by fictitious data.
