OSAKA -- Water supplies remained suspended for some 38,000 households in Hiroshima Prefecture on Sunday, one day after a powerful earthquake that left two people dead and 161 injured.

The quake, which hit a wide area of western Japan at 3:28 p.m. Saturday, partially damaged or destroyed more than 3,700 buildings, with most damage centering on Hiroshima and Ehime prefectures, local authorities said.

The temblor, which registered a lower-6 on the 7-point Japanese intensity scale in Hiroshima Prefecture, also caused extensive power outages, disrupted train services and forced highway authorities to temporarily close some roads in the Chugoku and Shikoku regions.
