Japanese authorities have asked hundreds of residents near Tokyo to evacuate as a sinkhole at an intersection grew to more than 40 meters wide, hampering rescuers racing to reach an elderly truck driver whose vehicle was swallowed by the hole.

Another sinkhole has since opened up nearby, and residents within a 650-foot radius had been evacuated, a spokesman said.

TOKYO -- An oval-shaped pit suddenly formed on a busy road in Yashio, Japan, on Tuesday, taking down a truck and trapping the driver inside. Emergency crews battled unstable ground and debris.
