In a short time James Churchward created New Age type of a book "Lost Continent of Mu, the Motherland of Man". It was followed by the book "The Children of Mu", then by "The Lost Continent Mu" and "The Sacred Symbols of Mu". These books enjoyed wild success at the times, and even now have their devotees.
In archives of web analytics company I found that even nowadays the search for a lost continent of Mu is still in progress. There were multiple researches on Mu and expeditions to various locations. Some called Easter Island a mountain top of a submerged continent of Mu. One well-known institute even suggested that underwater structures off the coast of Okinawa, Japan, were the ruins of Mu without any real scientific evidence. Some marine biologists stated that they identified the ruins of an ancient city off the coast of Japanese Yonaguni island as the remnants of an Asian equivalent of Atlantis and, that it was sunk three thousand years ago during an earthquake.
