  We introduce a new seismic wave representation model called PRIME-DP, which
stands for Pre-trained Integrated Model for Earthquake Data Processing. Unlike
most of the models, which are designed to specifically a singular problem,
PRIME-DP is used for multi-task single station seismic waveform processing.
PRIME-DP can be used to Pg/Sg/Pn/Sn phase picking, P polarization
classification. And can be fine-tunned to wide range of tasks, such as event
classification, without architecture modifications. PRIME-DP can achieve over
85% recall on Pg and Sg phases, when picking continuous waveform and achieves
over 80% accuracy in P polarization classification. By fine-tunning
classification decoder with NeiMeng dataset, PRIME-DP can achieve 95.1%
accuracy on event.
