A magnitude 6.2 earthquake struck Western Japan early Friday morning, according to the Japan Meteorological Agency, and several prefectures reported around 14 minor injuries but no casualties. The strongest intensity was felt in the Shikoku, Honshu and Kyushu islands although there was no tsunami alert issued.
The tremor originated from underground in Iyonada inland sea which is in the middle of Japan’s three major islands. Upper-5 intensity was registered in Seiyo, Ehime Prefecture while lower-5 was detected in Kure, Hiroshima Prefecture, Sukumo, Kochi Prefecture, and Usuki, Oita Prefecture. The JMA said that they are expecting intensity 4 aftershocks to occur in the next few weeks.
Firefighters in Okayama City said that a 70-year-old woman and two other residents sustained minor injuries while in Tamano, still in Okayama Prefecture, a 1-month-old infant was injured when his mother accidentally dropped him while trying to seek refuge. Hiroshima Prefecture also reported six minor injuries, and several more injuries were sustained by people in Hofu and Shimanto.
The Ikata nuclear plant in Ehime Prefecture did not detect any abnormality in their measurements, according to plant operator Shikoku Electric Power Co. They read 45 to 56 gals of ground acceleration during the quake but the plant is designed to withstand up to 570 gals. Residents around the plant expressed concern since the strongest intensity was detected in the prefecture, but Shikoku assured them there was no danger. Meanwhile, West Japan Railway Co said that their bullet trains between Okayama and Shin-Yamaguchi will slow down starting Friday as a safety precaution as more earthquakes are expected to come in the next few days.
