Restoration work began Sunday as aftershocks continued to rattle the island of Kozu following a 6.4-magnitude earthquake Saturday afternoon that killed one local resident.

The powerful quake jolted the island at 4:01 p.m. Saturday, causing landslides and disrupting water pipes in more than 20 locations. Kenichi Furukawa, 32, was killed after one of the landslides buried the car he was driving.

The temblor registered a lower 6 on the Japanese intensity scale of 7 on Kozu, a lower 5 on Niijima, and 4 on Miyake and in the town of Kawazu, Shizuoka Prefecture. Its focus was estimated at about 10 km off Kozu.
