this site tsunamihelp.blogspot.com is completely new but ranking in top 3 for the keyword tsunami, It is breaking our head what causes some new sites / new pages with sudden boost in backlinks not appearing in the top results of google,

Has been seeing lot of theories across various forums but none of them give real quality targeted information we need,

So what causes this sandboxing of sites, will it ever get released ?????
