摘要

Tsunami intensity on the Soloviev-Imamura scale is one of the most important parameters for characterizing the overall size of a tsunami generated by submarine earthquakes. Consequently, this parameter is included in both global tsunami databases maintained by the National Centers for Environmental Information/World Data Service (NCEI/WDS) and the Novosibirsk Tsunami Laboratory of the Institute of Computational Mathematics and Mathematical Geophysics (NTL/ICMMG). S. Soloviev made the initial evaluation of the intensities of a large number of destructive historical tsunamis while compiling his two historical catalogs of tsunamis in the Pacific. The Novosibirsk Tsunami Laboratory under the Expert Tsunami Database Project made further determinations of tsunami intensity for the events after 1975. These intensities have been periodically incorporated into the NCEI/WDS tsunami database under the Global Tsunami Database Joint ICG/ITSU-IUGG/TC Project. In the on-line version of the NCEI/WDS Tsunami Database, the data on tsunami intensity are available only for the events prior to 2003. The main purpose of this paper is to extend the temporal coverage of this important parameter for characterizing tsunamigenic events to the present in order to provide researchers with more data for analyzing the temporal and spatial tsunami occurrence. However, of the 164 tsunamigenic events in the World Ocean from 2000 to the present, we could determine the intensity value for only 44 events that is less than 27 % of the total. For the rest of the events (that is, 73 %), the intensity value cannot be determined due to the lack of data on wave heights from the nearest coast. This shows that despite a great improvement in the tsunami-recording network in the Pacific and other oceanic basins during the last two decades, the data for reliable estimates of tsunami intensity are still problematic.

Soloviev在编制了他在太平洋的两个海啸历史目录时，对大量破坏性历史海啸的强度进行了初步评估。专家海啸数据库项目下的新西伯利亚海啸实验室进一步确定了1975年以后事件的海啸强度。在全球海啸数据库联合ICG / ITSU-IUGG / TC项目下，这些强度已定期纳入NCEI / WDS海啸数据库中。在NCEI / WDS海啸数据库的联机版本中，海啸强度的数据仅适用于2003年之前的事件。本文的主要目的是将表征海啸事件的重要参数的时间范围扩展到为了向研究人员提供更多数据来分析时空海啸的发生。但是，从2000年到现在，在世界海洋中的164次海啸事件中，我们只能确定44次事件的强度值，这些强度值不到总数的27％。对于其余事件（即73％），由于缺少距最近海岸的波高数据，因此无法确定强度值。这表明，尽管在过去的二十年中，太平洋和其他海盆的海啸记录网络有了很大的改善，但海啸强度的可靠估计数据仍然存在问题。
