CREW Dataset

The Curated Regional Earthquake Waveforms (CREW) Dataset is a dataset of earthquake arrivals recorded at local and regional distances. CREW was assembled from millions of waveforms with quality control through semi-supervised learning. CREW includes 1.6 million waveforms that have global coverage. Each waveform consists of a 5 minute three component seismogram with labels for both a P and S arrival. CREW provides a high quality labelled waveform data set that can be used to develop and test machine learning models for the analysis of earthquakes recorded at regional distances.

精选区域地震波形数据集（Curated Regional Earthquake Waveforms，简称CREW）是一套收录近场及区域震中距处记录的地震波到时波形的数据集。该数据集通过半监督学习实施质量管控，从数百万条地震波形中整合构建而成。CREW数据集共包含160万条具备全球覆盖范围的地震波形，每条波形均为时长5分钟的三分量地震记录，并附带P波与S波的到时标注。本数据集提供高质量的标注波形数据，可用于开发、测试区域震中距地震分析相关的机器学习模型。
