Second big quake hits southern Japan, damage and death toll mounts | Reuters


TOKYO A magnitude 7.3 earthquake struck southern Japan early on Saturday, killing at least 11 people, injuring hundreds more and trapping people in collapsed buildings, media reported, just over a day after a quake killed nine people in the same region.

Authorities warned of damage over a wide area with reports of fires, power outages, collapsed bridges and gaping holes in the earth. Residents near a dam were told to leave because of fears it might crumble, broadcaster NHK said.

Saturday's quake triggered a tsunami advisory, although it was later lifted and no irregularities were reported at three nuclear power plants in the area, a senior government official said. There were at least 50 aftershocks from Saturday's quake.

People still reeling from Thursday's shock poured onto the streets after the Saturday earthquake hit at 1:25 a.m. (1625 GMT).

TV Asahi showed rescue efforts for what it said were 11 trapped people in a university apartment in the town of Minami Aso.

A fire erupted in a what appeared to be an apartment building in Yatsushiro city, while some people were trapped in a nursing home in the town of Mashiki, according to NHK.

NHK reported 11 deaths and 760 people treated in hospitals, but that figure included "people who don't feel well", so it was not clear how many serious injuries there were.

Chief Cabinet Secretary Yoshihide Suga said nearly 80 people were believed trapped or buried in rubble. Extra troops would be sent to help, with up to 15,000 due on Saturday, as well as more police, firefighters and medics, he said.

"We are making every effort to respond," Suga said.

Troops fanned out to search ruined houses as dawn broke.

The epicentre of the quake was near the city of Kumamoto and measured at a shallow depth of 10 kms (6 miles), the U.S. Geological Survey said. Almost 200,000 households were without power.

Prime Minister Shinzo Abe, arriving at his office, told reporters the government was making every effort to determine the extent of the damage, carry out rescue and recovery, and to get accurate information to citizens.

"It's possible that there may be damage over a wide area," Abe said.

The Japan Meteorological Agency initially said the Saturday quake was 7.1 magnitude but later revised it up to 7.3. The quake was 22 times more powerful, in terms of energy released, than Thursday's shock, according to the USGS website's "Magnitude Difference Calculator".

The region's transport network suffered considerable damage with one tunnel caved in, a highway bridge damaged, roads blocked by landslips and train services halted, media reported. Kumamoto airport was also closed.

Forecast heavy rain in the coming days could cause more landslides and affect already damaged structures, said the meteorological agency.

SHOCKS AND AFTERSHOCKS

Bank of Japan Governor Haruhiko Kuroda said it was too early to assess the economic impact and bank operations in Kumamoto were normal.

"We'll closely monitor the effect of the earthquake and take appropriate action, working closely with relevant authorities," Kuroda said in Washington after a G20 finance leaders' meeting.

Much of the area around Kumamoto and a few sizeable towns is rural. Television footage showed many frightened people wrapped in blankets sitting outside their homes while others camped out in rice fields.

The earthquake on Thursday evening in the same region was of 6.4 magnitude and experts said the tectonic events could be linked.

"Thursday's quake might have been a foreshock of this one," Shinji Toda, a professor at Tohoku University, told NHK.

Aftershocks rattled the region on Saturday, including two of nearly 6 magnitude, and experts warned of more. "We would not be surprised to see more earthquakes of this size," said John Bellini, a geophysicist with the U.S. Geological Survey.

A magnitude 9 quake in March 2011 north of Tokyo touched off a massive tsunami and nuclear meltdowns at Fukushima. Nearly 20,000 people were killed in the tsunami.

Japan is on the seismically active "ring of fire" around the Pacific Ocean and has building codes aimed at helping structures withstand earthquakes.

Factories in the area operated by manufacturers including Honda Motor (7267.T) and Sony Corp (6758.T) halted production after Thursday's tremor but no major damage was reported.

The 2011 quake temporarily crippled part of Japan's auto supply chain, but some companies have since adjusted the industry's "Just in Time" production philosophy in a bid to limit any repeat of the disruption.
