Quake victims huddle in a shelter

Aftershocks rattled survivors of deadly Japanese earthquakes, nearly a week after the first one struck, as the area braced for heavy rain later on Wednesday and the possibility of more landslides.

Rescuers using backhoes and shovels to dig through crumbled houses swept away in a landslide found a lifeless woman, one of several people still missing, taking the toll of dead to 47.

Hundreds of people in the Kumamoto area of southwestern Japan spent another night in their cars, afraid to return to damaged houses.

Medical experts warned of the danger of potentially fatal blood clots from sitting too long in cramped conditions – so-called economy class syndrome – after a 51-year-old woman died and at least 12 people were hospitalised because of it.

Eleven people appear to have died of illnesses related to their prolonged stay in evacuation centres, NHK national television said. The first quake hit late on April 14 and the largest, at magnitude 7.3, some 27 hours later.

“I keep thinking the earthquakes will stop, but they just go on and on,” one woman at an evacuation centre in Mashiki, one of the worst-hit areas, told NHK.

“It’s really scary.”

A 5.5-magnitude quake hit on Tuesday night. Of more than 680 aftershocks hitting Kyushu island since April 14, more than 89 have registered at magnitude 4 or more on Japan’s intensity scale, strong enough to shake buildings.

Nearly 100,000 people are in evacuation centres, some huddling in blankets outside as night temperatures fell as low as 8 Celsius (46 Fahrenheit) or queuing in long lines in the sun and 25C heat for bowls of noodles, their first hot food in days.

Heavy rain is expected over the area – 120 mm (4.7 inches) for Wednesday and early Thursday – raising fear that slopes weakened by the quakes could collapse.
