Global amplification factors for tsunami inundation

<strong>Global tsunami amplification factors used for estimation of tsunami run-up, based on wave input from offshore mariograms.</strong> The off-shore maximum surface elevation is multiplied by the factor to achieve the MIH estimation. Two sets of factors are included, one for the Mediterranean Sea (Glimsdal et al., 2019) and one set of global factors (Løvholt et al., 2012). The factors depends on the wave period, polarity and coastal location. The primary objective of this service will be to give scientists a tool for regional tsunami hazard evaluations, based on time series extracted by tsunami propagation models, without running computational costly run-up models along the coastlines. Example on global evaluation of MIH is found in Figure 2. The model will provide the following features: Interface for extraction of the wave characteristics from off-shore mariograms (time history of the surface elevation at a gauge) Extract the amplification factors based on the wave characteristics Calculation of the maximum inundation height Examples on Python-codes that can be used to calculate factors for different types of input will be added soon. The method is described in the following open access publications: https://link.springer.com/article/10.1007%2Fs00024-019-02091-w This service is part of the <strong>candidate Thematic Core Service for tsunami</strong> and will be integrated into the <strong>Integrated Core Service Data </strong>Portal of the <strong>European Plate Observing System (EPOS)</strong>.

本数据集提供用于海啸爬高估算的全球海啸放大因子，其输入数据取自近海潮位仪记录的海浪波形。将近海最大海面高程与该放大因子相乘，即可完成最大淹没高度（Maximum Inundation Height, MIH）的估算。数据集包含两套放大因子：一套适用于地中海海域（Glimsdal等，2019），另一套为全球通用因子（Løvholt等，2012）。该放大因子的取值取决于海浪周期、极性与沿海地理位置。本服务的核心目标是为科研人员提供一款区域海啸灾害评估工具，科研人员可直接利用海啸传播模型提取的海浪时间序列开展评估，无需在沿海区域运行计算成本高昂的爬高模型。全球最大淹没高度评估的示例详见图2。该工具具备以下三项功能：
1. 从近海潮位仪记录（测站海面高程时间序列）中提取海浪特征参数；
2. 基于提取的海浪特征参数获取对应放大因子；
3. 计算最大淹没高度。后续将新增可用于计算不同输入类型下放大因子的Python代码示例。该方法的详细说明可参考以下开源出版物：https://link.springer.com/article/10.1007%2Fs00024-019-02091-w
