The news of one of the worst calamities to hit the country in recent years shocked Nepalis everywhere, scrambling them to action.

"The minute I heard, I was like, non-action is not an option. I have to do something," said fashion designer Prabal Gurung who grew up in Nepal but now resides in New York.

Gurung, like many other Nepalis living abroad, quickly connected with his friends on Facebook and together launched a crowdfunding campaign on His fundraiser benefits Shikshya Foundation of Nepal, which has single-handedly raised over $485,000 of $750,000 goal in just a week.

"This is truly a wake-up call for our generation and the next to next. This is our calling, this is our time to really truly show up and walk the talk and build a sustainable, environmentally friendly country," he said.

It's not only the star power of people like Gurung that has attracted donations from the crowd. Thanks to the relative ease of Internet fundraising, many Nepali expatriates living in the U.S. and around the world have been equally involved.

Abhaya Shrestha is a private equity investor in New York who also heads the US chapter of Nepali charity called Help Nepal Network.

"I was flying back to New York from China when the quake hit Nepal. The news when I landed in JFK Airport made time standstill for a minute. I then sprinted in a mad rush to set up crowdfunding–and since then, so many Nepalis have joined the campaign to help people affected by the earthquake."

Mr. Shrestha's campaign raised over $250,000 around the world, in just a matter of days.

In addition to tragic loss of lives, the long-term economic impact of this tragedy is expected to be massive.

The U.S Geological Survey estimates that there's a 34 percent chance that total losses could exceed $10 billion, the rough equivalent of half the country's gross domestic product.

For now, Nepal's well-wishers around the world are helping to offset some of those staggering losses through donations on crowfunding sites, and sending money home for relief and rebuilding.
