The Nepal earthquake has caused an immeasurable amount of tragedy this weekend, but some internet services are offering tools that might provide comfort if you have friends or family in the area. Facebook has rolled out its recently introduced Safety Check feature to tell you if contacts in the area are okay -- survivors only have to report in to ease your mind. Google, meanwhile, has revived its longstanding Person Finder to assist you in both locating loved ones and sharing news with others. You'll want to get in direct contact or reach out an embassy if you're still concerned about affected locals, but these internet tools could spare you from a lot of uncertainty.
