\nThe possibility of a powerful earthquake of lower 6 or above on the Japanese seismic intensity scale of 7 occurring in the next 30 years has sharply increased in the eastern part of Japan’s northernmost prefecture of Hokkaido, a government report showed Tuesday.
The likelihood of such a strong earthquake jumped to 69 pct from 47 pct projected last year for the city of Kushiro and to 78 pct from 63 pct for the city of Nemuro. The new predictions are part of the 2018 National Seismic Hazard Maps for Japan compiled by the government’s Earthquake Research Committee. The report shows quake probabilities for sites where administrative centers of local governments are located. The higher risks reflected the committee’s new long-term forecast of a giant earthquake occurring along the Chishima trench off Hokkaido’s eastern coast, announced in December last year. The probability of a major earthquake with a magnitude of about 8 taking place at the trench off Nemuro within the next 30 years stands at around 80 pct, according to the committee’s latest hazard maps.
