Development for the early forecasting of tsunami by AIS data of the first in the world

2011年3月11日发生的日本东部大地震广泛影响了东北的整个太平洋沿海地区。历史上记录到的最大震级为9.0级。在沿海地区，这次地震引发了史无前例的海啸，造成了广泛的破坏。由于担心造成广泛破坏，人们认为海啸的早期预报被推迟了。本研究的目的是探讨利用近海多艘航行船舶的AIS数据进行海啸的早期预报。这项研究在世界上是第一次，非常有原创性。本研究得出的结论是，AIS资料有可能为海啸的传播提供早期预报。

The entire Pacific coastal region of the Tohoku was widely affected by the Great East Japan Earthquake that occurred on March 11, 2011. The maximum magnitude recorded in the history of earthquakes is 9.0. In the coastal areas, a historically unparalleled tsunami generated because of this earthquake, causing extensive damage. As the caution of extensive damage, it is considered that the early forecasting of tsunami was delayed. If the early forecasting of the propagation of tsunami becomes possible, it is considered that the extensive damage is reduced.The object of this study is to discuss about the early forecasting of tsunami by AIS data obtained from many sailing ships in coastal sea area. This study is the first in the world and very original. The conclusion obtained in the present study is that AIS data is possible to offer the early forecasting of propagation of tsunami.
