PKPPcP and PcPPKP Seismic Phase Observations for Mantle Heterogeneity

Yulong Su published a 2.3 GB dataset on figshare in 2026 containing seismic waveform and event data. The collection includes SAC waveform files and Excel tables detailing 94 events for PKPPcP analysis and 57 events for PKPPcP–PKKPab phase pairs analysis, along with corresponding event-station pair information. The data is used to study de-degeneracy effects of specific seismic phases and implications for 3-D Earth's mantle heterogeneity.

Use Cases

• Modeling 3-D mantle heterogeneity based on PKPPcP and PcPPKP phase observations described in the dataset.
• Analyzing de-degeneracy effects of seismic phases using the provided SAC waveform files.
• Correlating earthquake event parameters with station coordinates for specific phase-pair analyses.
• Validating seismic travel-time models using the catalog of 94 and 57 events with detailed event-station pairs.

Strengths

• Contains 2.3 GB of raw SAC waveform files suitable for seismic analysis.
• Includes detailed event catalogs for 94 and 57 specific earthquakes.
• Provides paired event and station coordinate information for traceable analysis.
• Released under a permissive CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the tabular data is unknown, which may limit suitability assessment.
• Data may reflect geographic or temporal bias inherent to the ISC earthquake catalog sources.
