Heinrich Kruparz is an Austrian geologist who has recently ventured into the world of Atlantology with the publication of Atlantis und Lemuria. From the title, he obviously supports the idea of sunken continents with advanced civilisations in both the Atlantic and Pacific Oceans. Like many others, he views the Azores as the remnants of Atlantis.
>Kruparz has also written a paper (in English) on the mysterious megaliths of Nan Madol(b).<
