We are constructing the Tsunami waveform Database (TwDB, doi:10.17598/NIED.0024) to manage and publish tsunami waveform data observed by tide gauges and ocean bottom pressure etc., which are dispersed different organizations and difficult to obtain for tsunami researchers. This database consists of a source information database, an observed waveform database, and a calculated waveform database for the past tsunamis, which the observed waveform data exist. Using this database, it is easy to compare the observed and calculated waveforms of tsunamis observed along the coast and offshore. However, since the database only covers past tsunami records, it is not possible to comprehensively investigate what kind of tsunamis can be induced by the expected source models recorded in the Tsunami Scenario Bank (TSB; doi:10.17598/NIED.0026). In this study, to improve disaster prevention, mitigation, preparedness for earthquake tsunami, we enlarged the Tsunami Scenario Bank (TSB) which contains calculated tsunami waveforms that can be compared with the Tsunami waveform Database (TwDB). Furthermore, we also construct tsunami inundation database to investigate the inundation areas could be induced by expected source models.
The TwDB has been constructed with the support of JSPS KAKENHI (database) JP20HP8014, and is continually under construct with the support of JP21HP8018, JP22HP8018, and JP23HP8015. This research has been partially supported by JSPS KAKENHI JP 20H00294. All calculations are conducted by the open source tsunami simulation code JAGURS.
