The post-earthquake studies have been started immediately with an attempt to diagnose the cause and behavior with respect to this disastrous earthquake occurred close to the end of 20 th Century.
Time advances soon after Chichi earthquake.
An international conference is timely to be held in giving an anatomy on it. In order to understand the complex geology of this region, we would like to combine the experience from studies of East Asian tectonics as well. We believe that this opportunity is helpful to scientists who have been working in this area and on relevant subjects. What also expected in this conference is that well-focused research objectives can be created and international collaboration can be enhanced. Main Theme iSEAT1 1.
