... surges and waves due to tropical cyclones have a great influence on the stability of coastal structures and the safety of coastal areas. Especially, there is a high risk at three major bays of Japan (Tokyo Bay, Ise Bay and Osaka Bay), where important coastal cities with high population areas are located...

... such as georeferencing method, presence/absence of the sea surface, and shooting altitude. The effect of the georeferencing method and shooting altitude was notable, while the effect of sea surface removal was relatively small. INTRODUCTION Port facilities are aging in Japan. The percentage of quays that are more...

... ABSTRACT This paper first reviews (1) the storm surge and wave disasters in the coastal and port areas of Osaka Bay and Tokyo Bay in Japan in 2018 and 2019, respectively and (2) two intensity levels of typhoons for coastal defense design and evacuation planning. Then, the paper summarizes...

... Abstract This paper reviews the ten–year–long progress from the 2011 Great East Japan Earthquake in tsunami monitoring and coastal defense in Japan. For instance, the GPS–mounted buoy system introduced a backup data transmission line while the networks of oceanfloor seismic and water pressure...

... ABSTRACT A Tsunami Simulator in Oceans and Coastal areas "T-STOC", which was developed by Port and Airport Research Institute, Japan, has been released as an open source computational code to simulate tsunami behavior from ocean to coastal area integrally. However, T-STOC does not support...

... ABSTRACT Significant seafloor massive sulphides, including copper, zinc, and silver, gold and so on, are distributed in the EEZ of Japan, including substantial deposits in the Okinawa Trough and Izu-Bonin back-arc basin. In 2008, the Japan Oil, Gas and Metals National Corporation (JOGMEC...

... ABSTRACT In July 2018, a disastrous storm along Osaka Bay, Japan, was caused by the Typhoon Jebi. The maximum height of observed sea level including storm surge was 3.29 m at Osaka. This value exceeded the highest record at Osaka caused Typhoon Nancy in 1961, whereas the maximum instantaneous...

INTRODUCTION Japan has strategic national interests in the Antarctic, and the Arctic, except for scientific activities...

... ABSTRACT Numerical simulations on inundation due to storm surge by scenario typhoons for structural design were carried out for ports along the three major bays of Japan assuming some different levels of sea level rise as impact of climate change, in order to evaluate the inundation risk due...
