Panic as deadly aftershock hits 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.

The 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. About 20 people were killed on Mount Everest in the April disaster, which saw vast avalanches of snow and rock careen down the world's highest mountain and smash into base camp, which was full of climbers from around the world.

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 earthquake that hit April 25 killed more than 8,150 and flattened entire villages, leaving hundreds of thousands homeless.

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 magnitude-7.8 earthquake, the country's worst-recorded quake since 1934.

CBS News correspondent Seth Doane says it is difficult to get aid out to those who need it as the infrastructure in Nepal -- already weak before the April 25 quake hit -- is so inadequate. People in the outlying areas of the country were forced to wait for days for helicopters to deliver aid supplies in the wake of the temblor three weeks ago.

An official at the U.S. Embassy in Kathmandu told CBS News that it had "no reports of injuries or fatalities of American citizens" but was still working to confirm the location of all those in the country.

The USAID Disaster Assistance Response Team (DART) currently positioned in Nepal was assessing the situation. Three American helicopters were taking 20 USAID DART members and 18 other urban search and rescue personnel to conduct initial assessments in Charikot, Nepal, near the epicenter.

The embassy official told CBS News that the approximately 300 U.S. military personnel in Nepal helping with relief efforts following the April 25 quake were working as needed in coordination with Nepalese authorities to respond to the aftershocks.

The USGS said the epicenter appeared to be 47 miles east of Kathmandu. CBS News' Sanjay Jha said he could feel the earth shake in New Delhi, India, some 700 miles away.

Olle Castel, of the British children's aid group Plan UK, has been in Kathmandu working on the response to the April 25 quake. He told Sky News Tuesday the aftershock lasted between 20 and 30 seconds, and his main concern was for the people near the epicenter, given the shallowness of the temblor.

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.

Tuesday's quake 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.

Tuesday's quake was followed closely by at least 10 strong aftershocks, according to the U.S. Geological Survey.

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 a well-known spot for high-altitude trekkers, said a couple of buildings damaged earlier had collapsed there as well. However, there were no reports of deaths or injuries in the town.

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