A powerful 6.6-magnitude quake rocked the northern Japanese island of Hokkaido Thursday, killing at least eight people, collapsing homes, and triggering landslides that left dozens missing.
Multiple, large-scale landslides struck the sparsely populated countryside, which was also hit by the edge of a powerful typhoon that surged through Japan earlier this week.
Aerial views showed dozens of houses destroyed at the bottom of a hill that was engulfed by a landslide, with a rescue helicopter winching a resident to safety. Around three million homes lost power after the quake damaged a major thermal plant supplying the region.
The Tomari nuclear power plant in Hokkaido, which was not operational before the quake, was forced to turn to emergency back-up power to keep its cooling system working, NHK said.
Kazuo Kibayashi, 51, a town official at hard-hit Abira town, told AFP: "There was a sudden, extreme jolt. I felt it went sideways, not up-and-down, for about two to three minutes."
Akira Fukui, from the main city of Sapporo, told AFP: "I woke up around 3am with a vertical jolt. I put the light on but it went out shortly afterwards. All the traffic lights are out and there's no power at work."
The risk of housing collapses and landslides had increased, he said, urging residents "to pay full attention to seismic activity and rainfall and not to go into dangerous areas."
