Australian Earthquake Ground Motion Data Collection

Segmented time series data for earthquake events. Data are in raw digital counts and have associated instrument metadata for calibration to physical ground-motion measures. These data are used to inform a range of applications in seismic hazard assessment and for assessing the utility of current observatory practice for magnitude assessment.

Value: Used in the selection and development of ground-motion models used for seismic hazard purposes. These data also enable the assessment and development of new earthquake magnitude formulae.

Scope: Data has been collected on an ad hoc basis, some early digital data dates back to 1989 (i.e. Newcastle earthquake), and the dataset continues to grow as earthquakes of interest occur, or various temporary deployments are rolled out. Instrument metadata is not always known.

本数据集为地震事件分段时间序列数据，采用原始数字计数格式存储，附带相关仪器元数据，可用于校准为物理地面运动度量值。该数据集可应用于地震危险性评估的多项场景，同时可用于评估现行地震台网观测规范在震级测算中的实用性。
数据集价值：可用于筛选与开发适用于地震危险性分析的地面运动模型，同时支持新型地震震级计算公式的评估与研发。
数据范围：本数据集以临时专案方式采集，部分早期数字数据可追溯至1989年（即纽卡斯尔地震事件），且随着目标地震事件的发生或各类临时观测台阵的部署，数据集规模仍在持续扩大。仪器元数据并非始终完备。
