Tsunami hazard probability in Japan

摘要: Abstract An analysis of future tsunami hazard on the coast Japanese Islands is made in terms probability for a coastal site being hit by tsunami, which wave height exceeds certain level during period from 2000 to 2010. Tsunami at Pacific estimated mostly based numerical experiment, typical fault model tsunami-generating earthquake assumed. Meanwhile, occurring 2010 evaluated either historical data occurrence or near-shore crustal strain accumulation. Combining estimate with evaluation occurrence, probabilities levels, are coast. It seems that violent 5 m, highest along central Japan, reaching value 41 per cent. On other hand, as high 69 cent found moderately large having 1 m so Shikoku and Kyushu coasts. A crude also tsunamis Japan Sea coast, where activity substantially lower than The amount only 10-yr period. Similar excited distant source off Peru, Chile, Kamchatka, Aleutian-Alaska evaluated. In this case, exceeding 3 are, respectively, 19 15 such not quite negligible.
