Nabro Volcano Seismic Event Catalogue from U-GPD Model, Sep 2011 - Oct 2012

A catalogue of seismic events from Nabro volcano between September 2011 and October 2012. Events were detected and located using the U-GPD phase arrival picking model, a transfer learning approach. The dataset was created by Sacha Lapins of the University of Bristol and is associated with a 2021 paper in JGR Solid Earth.

Use Cases

• Analyzing spatio-temporal patterns of volcanic seismicity based on event origin times and hypocentre locations.
• Validating and comparing seismic event detection algorithms using the U-GPD model's phase arrival picks and probabilities.
• Studying seismic source characteristics and error estimation using the provided RMS, horizontal/vertical error, and azimuthal gap columns.
• Investigating seismic event clustering behavior using the HDBSCAN cluster numbers assigned to each event.

Strengths

• Includes detailed event location parameters such as latitude, longitude, depth, and error estimates.
• Provides phase arrival times and detection probabilities for multiple seismic stations (NAB*), enabling waveform analysis.
• Dataset is fully reproducible with associated code and model archived on GitHub and Zenodo.
• Based on publicly available seismic waveform data from the Nabro Urgency Array accessible via IRIS Data Services.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Column-level documentation is provided in the description but the actual data file and its completeness require manual inspection after download.
• Last update date is unknown; freshness unverified beyond the 2011-2012 observation period.
