Study on regional and historical change of tsunami disasters

召开了日本、印度尼西亚、韩国、美国、墨西哥、俄罗斯、英国、法国、希腊和土耳其与会者讨论海啸灾害和减灾的国际会议。主题分为四个：(1)海啸现象，(2)海啸模拟的应用，(3)非地震源引发的海啸，以及(4)较低地区的减灾和恢复，以澄清有关Waming的地区性和普遍性问题。S与文化、生活和土地利用相关的数值模拟、生成机制和区域灾害。编制了应对措施、预警、灾害文化的综合比较，有助于探讨世界各国通过合作减轻和恢复灾害的方式。从分辨率和数值方法上的准确性，以及探测系统中海啸观测模型的可靠性等方面，讨论了预警系统和危险图实时数值模拟的可能性。选取1998年巴布亚新几内亚海啸和1999年瓦努阿图海啸为典型实例，研究海啸的震源机制和数值预报。

The international meeting to discuss the tsunami disaster and mitigation by participants from Japan, Indonesia, Korea, US, Mexico, Russia, UK, France, Greece, and Turkey was held. The topics are divided into four ; (1) tsunami phenomena, (2) utilization of the tsunami simulation, (3) tsunami generation due to non-seismic source, and (4) mitigation and recovery in orer to clarify the regional and universal problems on waming. Numerical simulation, generation mechanism and regional disaster s related with culture, life and land-use. The comprehensive comparison of counter-measurement, warning, disaster culture are compiled, which is useful to discuss the way of mitigation and recovery through cooperation in the world. The possibility of numerical simulation in warning system in real time and hazard map is discussed in accuracy on resolution and numerical methods, and reliability of the model with observation of the tsunami in detecting system. The 1998 Papua New Guinea and 1999 Vanuatu tsunami are selected as typical example to study the tsunami source mechanism and numerical forecasting.
