Another deadly earthquake spreads fear and misery in Nepal

KATHMANDU, Nepal -- A new earthquake killed dozens of people Tuesday and spread more fear and misery in Nepal, which is still struggling to recover from a devastating quake nearly three weeks ago that left more than 8,000 dead.

A U.S. Marine Corps helicopter carrying six Marines and two Nepalese soldiers was reported missing while delivering disaster aid in northeastern Nepal, U.S. officials said, although there have been no indications the aircraft crashed.

Tuesday's magnitude-7.3 quake, centered midway between Kathmandu and Mount Everest, struck hardest in the foothills of the Himalayas, triggering some landslides, but it also shook the capital badly, sending thousands of terrified people into the streets.

Nepal's Parliament was in session when the quake hit, and frightened lawmakers ran for the exits as the building shook and the lights flickered out.

At least 37 people were killed in the quake and more than 1,100 were injured, according to the Home Ministry. But that toll was expected to rise as reports began reaching Kathmandu of people in isolated Himalayan towns and villages being buried under rubble, according to the U.N.'s Office for the Coordination of Humanitarian Affairs.

Tremors radiated across parts of Asia. In neighboring India, at least 16 people were confirmed dead after rooftops or walls collapsed onto them, according to India's Home Ministry. Chinese media reported one death in Tibet.

The magnitude-7.8 earthquake that hit April 25 killed more than 8,150 and flattened entire villages, leaving hundreds of thousands homeless in the country's worst-recorded quake since 1934. The U.S. Geological Survey said Tuesday's earthquake was the largest aftershock to date of that destructive quake.

Tuesday's temblor was deeper, however, coming from a depth of 18.5 kilometers (11.5 miles) versus the earlier one at 15 kilometers (9.3 miles). Shallow earthquakes tend to cause more damage.

At least three people were rescued Tuesday in Kathmandu, while another nine pulled to safety in the district of Dolkha, the government said.

Rescue helicopters were sent to mountain districts where landslides and collapsed buildings may have buried people, the government said. Home Ministry official Laxmi Dhakal said the Sindhupalchowk and Dolkha districts were the worst hit.

Search parties fanned out to look for survivors in the wreckage of collapsed buildings in Sindhupalchowk's town of Chautara, which had become a hub for humanitarian aid after last month's quake.

Impoverished Nepal appealed for billions of dollars in aid from foreign nations, as well as medical experts to treat the wounded and helicopters to ferry food and temporary shelters to hundreds of thousands left homeless amid unseasonal rains.

In Washington, Navy Capt. Chris Sims said the missing Huey helicopter was conducting disaster relief operations near Charikot, Nepal.

A nearby Indian helicopter heard radio chatter about a possible fuel problem, said U.S. Army Col. Steve Warren. The Huey, carrying tarps and rice, had dropped off supplies and was headed to a second site when contact was lost, he said, adding that there has been no smoke or other signs of a crash.

A Nepalese air brigade unit had seen the Huey, so Marines in V-22 Osprey aircraft searched unsuccessfully near its last known location for about 90 minutes, Warren said. Members of the Nepalese army are searching on foot because of darkness, he added.

Due to the rugged terrain, the helicopter could have landed in an area where the crew was unable to get a beacon or radio signal out, Warren said.

Tuesday's quake was followed closely by at least 10 strong aftershocks, according to the USGS.

Early reports indicated at least two buildings had collapsed in Kathmandu, though at least one had been unoccupied due to damage it sustained on April 25. Experts say the earlier quake caused extensive structural damage even in buildings that did not topple, and that many could be in danger of collapse.

Frightened residents in the capital, who had returned to their homes only a few days ago, once again set up tents Tuesday night with plans to sleep in empty fields, parking lots and on sidewalks.

"Everyone was saying the earthquakes are over. ... Now I don't want to believe anyone," said 40-year-old produce vendor Ram Hari Sah as he searched for a spot to pitch the orange tarpaulin to shelter his family. "We are all scared, we are terrified. I would rather deal with mosquitoes and the rain than sleep in the house."

Extra police were sent to patrol ad-hoc camping areas, while drinking water and extra tents were being provided, according to Kathmandu administrator Ek Narayan Aryal.

"I thought I was going to die this time," said Sulav Singh, who rushed with his daughter into a street in the suburban neighborhood of Thapathali. "Things were just getting back to normal, and we get this one."

Paul Dillon, a spokesman with the International Organization for Migration, said he saw a man in Kathmandu who had apparently run from the shower with shampoo covering his head. "He was sitting on the ground, crying," Dillon said.

Meanwhile, new landslides blocked mountain roads in the district of Gorkha, one of the regions hit hardest on April 25, while previously damaged buildings collapsed with the latest quake.

Residents of the small town of Namche Bazaar, about 50 kilometers (35 miles) from the epicenter of Tuesday's quake and well known to high-altitude trekkers, said a couple of buildings damaged earlier had collapsed there as well. However, there were no reports of deaths or injuries.

The earth also shook strongly in neighboring Tibet, unleashing a landslide that killed one person and injured three, according to China Central Television. Two houses collapsed, the state broadcaster said, quoting disaster officials of the regional Tibetan government.
