When tsunami attacks an island, there are some cases that the island is damaged seriously by the trapping phenomena of tsunami. Iin this study, theoretical solution on the trap of long wave by a conical island is obtained by taking account of the effects of both finite radius of the island and the wave refraction on the sloping beach. The theoretical solution are examined carefully to find the …
Tsunamis that enter rivers usually take the form of cnoidal bores, a series of solitons, even if they are in the form of breaking bores at the beginning. The path of a tsunami on land is sometimes not simple, governed by its inertia and by the local topography. A huge tsunami can override small hills or cross over passes and attack villages from behind. In 1611, O-ura, a small fishing village i…
