What it does

This skill documents end-to-end seismological data processing using the ObsPy ecosystem. It walks through connecting to FDSN nodes (IRIS, GEOFON), downloading MiniSEED waveforms and StationXML inventories, removing instrument response to convert counts to physical units, pre-processing (detrend/taper/filter), automatic P/S picking with STA/LTA, basic moment-tensor and travel-time analyses, spectrograms, cross-correlation, and seismicity mapping. The SKILL.md contains runnable Python examples and plotting recipes.

When to use it

Use this skill when analysing recorded seismic waveforms for research or rapid post-event assessment: retrieving archived waveforms, preparing data for phase picking, estimating source parameters, generating seismicity maps, or producing publication-quality diagnostic plots. Not intended for real-time continuous acquisition or extremely large distributed arrays.

What's included

References: ObsPy docs, TauPy model references, FDSN service links
Instructions: environment setup (pip/conda), recommended pre_filt/water_level parameters, STA/LTA tuning advice, and troubleshooting for common FDSN/response issues.
