The tool has logged more than 5,700 records in the past two days and is also searchable via text message.
Facebook, meanwhile, activated its safety check tool that notifies people in the affected area that they can send an alert to friends to let them know they are safe.
Aside from leveraging the reach of the Internet, several other technology companies are offering help in getting phone calls and text messages in and out of Nepal.
T-Mobile and AT&T announced all fees will be waved for customers who called and texted Nepal beginning on Saturday and extending through May 16.
Viber, an Internet calling company, announced on Twitter it was making all calls to and from Nepal free of charge during the aftermath.
Google Voice calls are also being made available for the reduced rate of 1 cent per minute. According to a post on Google's Asia Pacific blog, the small cost was chosen as a way "to prevent spammers from abusing our systems and possibly adding more load to the already stretched Nepalese telephone network."
Since the Saturday earthquake and aftershocks, the death toll has risen to more than 3,700, according to a Nepal police official.
Of those, Stoneham said 75 U.S. citizens are reported to be sheltering in the embassy, while about 150 others are sheltering at the Phora Durbar compound.
