Bathymetry Data and Tsunami Waveforms of the 2011 Tohoku Earthquake in Hangzhou Bay

Phys. Fluids 33, 081702 (2021); doi: 10.1063/5.0059383 <br> 1) Bathymetry bathy.SD01.grd Bathymetry file of the whole research region (0.9 arc min) bathy.SD02.grd Bathymetry file of Hangzhou Bay (0.3 arc min) <br> The bathymetry data used in this work are derived from General Bathymetric Chart of the Ocean released in 2020. We note that the range of bathy.SD02.grd is 120.0/123.0/29.7/30.99. We slightly move the northern edge of the grid file from 31.0N to 30.99N to meet the requirement of JAGURS. According to the requirement, the grid size ratio between the neighboring layers should be 3:1, and the edges of coarse and fine grids should be strictly fitted. <br> 2) Tsunami Waveform i) Observed There are observed raw records at four tide gauges, from 2011-Mar-10 00:00:00 (China Standard Time) to 2011-Mar-12 23:59:59. The sampling is 60 s. The unit is cm. <br> ii) Synthetic The sampling rate is 0.25 s. The time series have a total length of 24 hr. The waveform file has the name of 'tgs0000XX_Extracted'. XX is the number of the tide gauge.

The first column is the time (s) after the earthquake origin time. The second column is the tsunami height (m).
