More intensive earthquakes.

After Australia broke away from Antarctica about 90 millions ago in the Cretaceous, the earth continental intensively moving fragmented and collided, the island collided each others more and more in the present time. Australia, New Guinea and east Sulawesi proceeded to travel northwards at about ten cm per year. At least part of Eastern Sulawesi probably separated from New Guinea before its mid Miocene collision with western Sulawesi after which the Eastern half began to emerge as an island (Audley-Charles in press) The most dramatic evident in Indonesian geological history occurred in the Miocene when the northwatd drifting Australian plate caused the bending to the west of of Eastern part of the Banda Arc. The westward movement coupled with the westward thrust along the east west Sorong fault system from western Irian modified the two major land masses that would form the peculiar shape of Sulawesi recognised today. It has been proposed that collision occurred 19-13.Ma ago, Sasajima ET all., 1980. Audley-Charles). The Banggai Sula islands formed the continental platform section of the east Sulawesi fragment. The Talaud islands and the small islands of Mayu and Tifore between North Sulawesi and Halmahera are probable also party of the collision suture that formed between Sundaland and Gonwanaland. (Audley-Charles in press). From these geological evident we are threatened by tectonic fragment where we are survived from these Oceania archipelagoes, now scientists are not so much active in informing us how dangerous is to live in the dissected connection lands between Asia and Australia and entire Oceania islands. I hope the post can provocateur scientist to introduce this phenomenon to us.
