The Name of a Place

I've read an article about the name of a place in Hiroshima where the massive landslid has occered. The place is simply called Yagi, but it used to be called Yagijarakujiasidani, 八木蛇落地悪谷. Looking at the kanji, it doesn't seem a good place to live. 

They said, the name of a place is a fossil of the history. If you want to have a house, I think you should look up the name of the place carefully. The name would tell you something.
