| Abstract: | Tsunami from Makran subduction zone in the northern Arabian sea are seen to
arrive at Ratnagiri (16°56´24.00˝N, 72°40´12.00˝E) along the west coast of
India 8 minutes earlier than Mumbai (18°59´24.00˝N,71°52´12.00˝E) in spite
Ratnagiri being 244 km down south of Mumbai. This can give rise to a false
signal and could be interpreted as tsunami skipped Mumbai and is traveling
towards south. However, this advance information at Ratnagiri could be used for
quick evacuation of densely populated coastal areas of Mumbai. Reasons for
later arrival of tsunami at Mumbai is mainly due to a wide shelf of greater
than 250 km whilst at Ratnagiri the shelf suddenly becomes half that of Mumbai.
The importance of shelf width along the west coast of India which plays a great role in
the arrival of the tsunami waves and the wave heights at different locations
are conferred in the present study. |
