CEED: California Earthquake Event Dataset
2.4 million analyst-labelled earthquake seismograms from California, 1977–2025.
One record is one earthquake recorded at one station: a 122.88 s three-channel waveform with an
analyst-picked P arrival, an analyst-picked S arrival, and the analyst's reading of the P
first motion (up or down). Every trace carries the recording network's own hypocentre, magnitude
and arrival-quality numbers, so the labels can be filtered on quality… See the full description on the dataset page: https://huggingface.co/datasets/AI4EPS/CEED.CEED
SeismicXM 单台震中距、反方位角与震级预测
该目录实现 5 类严格可比的 SeismicXM 实验：
decoder：只训练新的三任务回归头；
encoder_decoder：训练卷积/双向 LSTM 编码器与回归头；
transformer_decoder：训练 Transformer、任务嵌入与回归头；
encoder_transformer_decoder：加载预训练权重后全量微调；
scratch：同一结构从零训练，先训练到 1,000 step，再从该权重继续到总计 20,000 step。
默认采用 SeismicXM middle（约 51M 参数）及其发布权重。前三个目标分别用 km、圆周角和震级的独立指标报告。方位角定义为台站指向震中的 back azimuth；CEED HDF5 中保存的 azimuth 是震中指向台站，因此标签加 180° 后取模。
数据与预处理
从 CEED/NC 年度 HDF5 中选 20,000 条训练波形、2,000 条验证波形和 2,000 条测试波形。… See the full description on the dataset page: https://huggingface.co/datasets/heidiXD/CEED.Compact_Sub-Stationhttps://www.ceedelectric.com/product/customized-electrical-equipment-compact-sub-station-swithgear/
