Second deadly quake hits Japan, 'race against time' to find survivors

Japanese rescuers were digging through the rubble of buildings and mud on April 16 to reach dozens believed trapped after a powerful 7.3 magnitude earthquake struck a southern island, killing at least 26 people and injuring about a thousand.

The shallow earthquake hit in the early hours, sending people fleeing from their beds on to dark streets, and followed a 6.4 magnitude quake on April 14 which killed nine people in the area. Rain and cold were forecast overnight, adding extra urgency to the rescue effort.

Television footage showed fires, power outages, collapsed bridges, a severed road hanging over a ravine and gaping holes in the earth. Residents near a dam were told to leave because of fears it might crumble, broadcaster NHK said.

"I felt strong shaking at first, then I was thrown about like I was in a washing machine," said a Tokai University student who remains isolated in the village of Minamiaso in Kumamoto province on the island of Kyushu.

"All the lights went out and I heard a loud noise. A lot of gas is leaking and while there hasn't been a fire, that remains a concern," the student, who is sheltering in a university gym with 1,000 other students and residents, told Japanese media.

About 190 of those injured were in serious condition, the government said.

Many frightened people wrapped in blankets sat outside their homes while others camped out in rice fields in rural areas surrounding the main towns. About 422,000 households were without water, and about 100,000 without electricity, the government said. Troops were setting up tents for evacuees and water trucks were being sent to the area.

Heavy rain and wind were forecast, with temperature expected to drop to 13 degrees Celsius (55 degrees Fahrenheit)...
