Families can register their missing loved ones on this site here. Families say on the site they are looking for Eric Camran Chaudhary, 28, from Charlotte, and David Huizenga, 49, from Grand Rapids.
A third and fourth person are also reported missing on the site: 19-year-old Owen Cousino from Ypsilanti, and 27-year-old Christine Bedenis from Plymouth. They are reported safe, though.
Owen's church says on social media he has contacted his family and is okay. Bedenis tweeted Monday morning that she is also safe.
In Nepal, rescuers are still trying to get to remote villages at this hour. The death toll climbed above 3,700 on Monday.
How much higher the death toll would rise depends on the state of remote Himalayan villages that rescue workers were still trying to reach. Many of the roads are believed to be cut off by landslides, making it likely that some of these communities can only be reached by helicopter.
The earthquake hit the capital, Kathmandu, but its impact spread far beyond. At least 18 people died on the slopes of Mount Everest, where avalanches buried part of the base camp packed with foreign climbers. Three Americans were killed in the avalanche. Another 61 people were killed in neighboring India, and China reported 20 people dead in Tibet.
Nearly 100 aftershocks, including a magnitude-6.7 temblor Sunday, have hindered rescue efforts and terrorized residents sleeping in open squares and parks.
Kathmandu is full of small, poorly constructed brick apartment buildings, and the quake destroyed swaths of the oldest neighborhoods, even as more modern structures stood firm. Most areas were without power and water.
The quake was the worst to hit Nepal in at least 80 years. Nepal's worst recorded earthquake in 1934 measured 8.0 and all but destroyed the cities of Kathmandu, Bhaktapur and Patan.
Meanwhile, relief efforts are ramping up around the glove.
The U.S. has sent a disaster response team, as well as 45 tons of equipment.
The United Nations said hospitals in the Kathmandu Valley were overcrowded and running out of emergency supplies and space to store corpses.
Some pharmacies and shops for basic provisions opened while bakeries began offering fresh bread. With power lines down, spotty phone connections and almost no Internet connectivity, residents were particularly anxious to buy morning newspapers.
Huge lines of people desperate to secure fuel lined up outside gasoline pumps; prices were the same as they were before the earthquake struck.
The first nations to respond were Nepal's neighbors - India, China and Pakistan. The United States, Canada, the United Arab Emirates, Britain, Germany, France, Poland, Italy, Israel and Singapore also sent aid.
