In the aftermath of the March 11 earthquake, tsunami and ongoing nuclear crisis, social media played a key role in raising funds for victims in the earthquake and tsunami-hit region.

Through social media and e-book publications, several fundraising efforts have come to fruition in the form of books. Here are two books that support relief and recovery efforts.

#quakebook 2:46 Aftershocks: Stories from the Japan Earthquake

2011, 102 pp., $11.99, paperback (free on Kindle)

Shortly after March 11, a British man living in Japan only known as “OurManInAbiko” on Twitter, started to gather stories about the aftermath of the earthquake.

He soon found support in a team of writers, publicists and artists, all working toward one goal: to create a Twitter-sourced book to raise money for the relief efforts in northern Japan.

With a total of 89 submissions, including those from Yoko Ono and Barry Eisler, the book holds both star-power and humanitarian sympathy.

The book recently was re-released as a bilingual paperback and is now available for sale online and at Kinokuniya Book Stores in the U.S. The original digital copy is now free to download.

All funds aid the Japanese Red Cross.

Shaken: Stories for Japan

2011, $3.99, on Kindle

Twenty authors contributed work to an anthology of short stories concerning Japan in “Shaken: Stories for Japan.”

All royalties will go directly to the 2011 Japan Relief Fund administered by the Japan America Society of Southern California. The funds will be distributed to non-governmental organizations in Japan for humanitarian relief and long-term recovery efforts for areas devastated by the earthquake and tsunami.

This collection is edited by award winning mystery writer Timothy Hallinan. Numerous other writers also contributed to the book.
