Earthquake victims in central Japan have spent the night in shelters as aftershocks continued to jolt the area following a strong quake Sunday that killed one person and injured more 160 others.
The six-point-nine magnitude quake struck at 9:42 am local time (0042 UTC) in the Sea of Japan, off the northern coast of Honshu island, flattening dozens of houses and partially destroying hundreds others.
The worst hit was the city of Wajima in Ishikawa prefecture. Japanese authorities issued a tsunami alert but it was lifted after a 10-centimeter wave hit the shore, causing no damage.
At around the same time, two strong earthquakes shook the Pacific island nation of Vanuatu, but there were no reports of injuries or damage.
The first quake had a magnitude of seven-point-three, followed 28 minutes later by a seven-point-one magnitude quake centered about the same spot.
