A magnitude-6.7 aftershock rumbled Kathmandu and sent people running for open ground Sunday morning, a day after a massive 7.8-magnitude earthquake ravaged Nepal and the region and killed more than 2,100 people.
The U.S. Geological Survey said the aftershock, the largest of numerous aftershocks rattling frightened residents, registered at a shallow depth of 6 miles.
Minutes later, Nepal felt another aftershock measuring 5.0 in magnitude, says the Indian Express.
Sunday's quake was close to Mt. Everest, sending down new avalanches of snow and rock, reports CNN.
"An earthquake that long set off avalanches all the way around us," Jon Reiter, an American mountaineer at the Napelese base camp, told CNN. "And they came down — they were large, they were massive avalanches."
Rescue helicopters lifted the wounded from the slopes. At least 17 people died at the base camp and 61 were injured, AP says.
Rescues crews were dispatched from around the world to the region, but severed communications and landslides hindered the effort, India sent four planes carrying 450 disaster relief personnel, which reached the country Sunday. China dispatched a 62-member search team, reports the Wall Street Journal.
The United States is giving $1 million in immediate assistance and preparing a response team, says CNN. Britain, Pakistan and European Union countries are among nations sending teams, said the BBC.
In Kathmandu, tens of thousands endured freezing temperatures to sleep outside overnight for fear of further quake damage. Rescue workers and international aid teams started out at dawn to dig through rubble and debris in a desperate search for survivors.
Hospitals struggled to cope with the wounded. Reuters quotes a paramedic who said Kathmandu's Bir Hospital had received 300 to 350 patients with severe injuries; most of them died, he said.
According to the AP:
"In the Kalanki neighborhood, police rescuers tried to extricate a man lying under a dead person, both of them buried beneath a pile of concrete slabs and iron beams. His family members stood nearby, crying and praying.
"Police said the man's legs and hips were totally crushed.
" 'We are digging the debris around him, cutting through concrete and iron beams. We will be able to pull him out but his body under his waist is totally crushed. He is still alive and crying for help. We are going to save him,' said police officer Suresh Rai."
