Post-event survey of locally concentrated disaster due to 2019 Typhoon Faxai along the western shore of Tokyo Bay, Japan

Coastal destruction and unusual wave spectra induced by Typhoon Faxai in 2019

“…The coastal destruction was reported in detail by Suzuki et al (2020). From a wave physics point of view, two intriguing phenomena were reported in Suzuki et al (2020), which motivated this study.…”

“…The coastal destruction was reported in detail by Suzuki et al (2020). From a wave physics point of view, two intriguing phenomena were reported in Suzuki et al (2020), which motivated this study. The first was that although the storm impacted the whole bay, significant damage was concentrated in a small area (relative to the size of the bay).…”

“…White and blue stars in the Bay indicate observation sites at Daini-kaiho and Tokyo port, respectively. Locations where wave runup and/or inundation height exceeded 3 m from the mean sea level are marked with pink crosses (data from post-event survey by Suzuki et al (2020)). Black lines with squares indicate four port areas on the western side of Tokyo Bay.…”

“…These storms have wreaked havoc in coastal areas (e.g. Mori et al 2019;Shimozono et al 2020;Suzuki et al 2020), and unfortunately, the Japanese coasts are expected to experience this issue more frequently as the risk of typhoons rises in East Asian countries (Kossin, Emanuel, and Vecchi 2014;Tsuboki et al 2015;Mei and Xie 2016). Typhoon Faxai (T1915), which occurred in September 2019, was one of the strongest typhoons on record to make landfall in the Kanto region (Tokyo metropolitan area), Japan, and it caused extensive damage along the coast.…”

“…The second intriguing observation in Suzuki et al (2020) was related to the direction of the hazardous waves. They estimated the direction of wave overtopping around the Port of Yokohama based on tracing the debris of collapsed fences and vegetation.…”
