Facebook introduced a new app this week from some wonderful lessons learned a few years back when the Tsunami struck Sri Lanka and other coastal countries along the Indian Ocean. Families, friends and loved ones we’re desperately seeking any form of communication that they could get from those lost within the devastation of the Tsunami. Phone lines we’re down, internet services we’re down, and cell phone signals became hit and miss due to overload.

It was a relief for some to get a short message on Facebook that they we’re okay and would contact again when they could. This gave Facebook the idea to create an app that could notify loved ones quickly.

The new app, called Safety Check, takes note of the user’s home city and in the event of an emergency, Facebook will send out a text message to those people that simply asks’ “Are you Okay?” at that point when the person responds a “yes” will be instantly communicated out to loved ones via the Facebook news feed.

Facebook has shown itself this week to be a powerful force in helping man-kind with the use of social media.
