As well as the "Donate" feature, Facebook is also enabling users to indicate that they are safe using the social network's "Safety Check" tool.

Users in areas affected by the earthquake will receive a Facebook notification asking if they are safe, and will be able to reassure friends and familiy with the touch of a button.

Facebook said millions of users in Nepal, India, Bhutan and Bangladesh had been marked as safe, and their status had been relayed to tens of millions of people as of Monday afternoon.

"During times of crisis, we have seen people turn to Facebook to learn about what's happening, share their experiences and support one another," said Facebook in a blog post.

"By offering tools to help people donate to support those in the affected areas and check on loved ones, we're hopeful that together we can promote safety and help urgent resources reach those who need them."

Facebook is not the only technology company offering resources to help the relief effort. Apple is asking iTunes users to donate money to the American Red Cross through its iTunes Store, and Twitter is helping to raise funds through UNICEF.

Meanwhile, Google is working to get updated satellite imagery to aid in the recovery effort, and has launched its Person Finder tool to help people determine whether those who may have been in the area of the earthquake are safe.

Person Finder collates information from emergency responders and allows individuals to post details about relatives missing or found. The result is a searchable, online database.

One of Google's own employees, engineer Dan Fredinburg, was among at least 17 climbers killed when an avalanche hit their base camp on Mount Everest, following the 7.8-magnitude earthquake.

"Google.org is committing $1m to the response, and we'll have gift-matching available soon," said Google's Lawrence You in a Google+ post. "Our thoughts are with the people of Nepal, and with Dan's family and friends during this terrible time."
