International symposium: Geological and paleogeographical evolution of the Ryukyu Islands in the late Cenzoic
Conveners: Yasufumi Iryu(Tohoku Univ.),HidetoshiOta(Univ. Hyogo/Mus. Nature and Human Activities),Kohsaku Arai(GSJ, AIST)

The Ryukyu Islands(Ryukyus)are situated to the southwest of mainland Japan and encompasses several tens of islands and islets, extending from Tane-ga-shima in the northeast to Yonaguni-jima in the southwest. Most islands in the Central and Southern Ryukyus are rimed by modern coral reefs and are covered with the Quaternary carbonates deposited in reefs and associated shallow lagoons and island shelves. The current terrestrial fauna and flora in the Ryukyus are characterized by a high frequency of endemic taxa. Based mainly on geological data including those for the Pleistocene fossils, some hypotheses were once presented for the paleogeographic changes, which supposedly caused coral reef‘turn-on’and gave rise to the current characteristic phylogeographical patterns in various terrestrial organismal lineages in the Ryukyus. However, recent molecular phylogenetic and evolutionary studies have yielded data that are obviously incongruent with those previous hypothetical scenarios. This symposium aims to integrate the latest geological and biogeographic data in the Ryukyus and create a new hypothesis for tectonic evolution of the islands.

Concern about the outcome of the L’Aquila prosecution

JGS Release

Concern about the outcome of the L’Aquila prosecution

The geological Society of Japan wishes to express its grave misgivings about the way in which 6 geoscientists were held to be guilty of manslaughter as a result of the 2009 L’Aquila earthquake in Italy.

The L’Aquila earthquake resulted in the death of more than 300 people and widespread destruction to a culturally important area. This is a tragic loss and our thoughts are with the victims. It is important that lessons are learnt from this and other similar events to contribute to a better understanding of earthquake disaster and how risk governance can be improved. Geoscientists have a central role in this process.
