obspy-seismology

What problem does it solve?

This Skill helps you download, preprocess, and analyze seismic waveforms to extract physically meaningful earthquake information without manually stitching together multiple seismology tasks.

Core Features & Use Cases

• Waveform download & preprocessing: Fetch waveforms from FDSN services (e.g., IRIS), remove instrument response (when inventory is available), otherwise apply bandpass filtering, and produce publication-ready seismogram plots.
• Phase picking & travel-time modeling: Detect P/S arrivals using STA/LTA onset picking and compute theoretical phase travel times using TauP (iasp91/PREM-style workflows).
• Spectral analysis & magnitude estimation: Estimate displacement spectra, fit a Brune source model, and compute moment magnitude from spectral parameters (with an end-to-end workflow including receiver-function-style deconvolution).

Quick Start

Use the obspy-seismology skill to download an earthquake waveform window, remove instrument response (or filter if unavailable), pick P/S arrivals, compute TauP travel times, and generate spectral-based moment magnitude estimates.
