When the massive earthquake struck Nepal’s Kathmandu Valley last April, I was about to board a plane on the other side of the country. Not knowing about the quake, I landed in Kathmandu less than two hours later surrounded by panic and devastation – buildings had crumbled, people were trapped, and electricity supplies and mobile phone networks were down.
But there was a wifi connection so I quickly logged onto Facebook on my phone to tell family and friends that I was OK.
And I was not alone. All over the valley and the world, people were using Facebook to communicate about the quake.
