Complete seismic swarm analysis guide for volcanology practitioners. Step-by-step workflow with 4 stages and 3 specialized tools. Covers detect swarm onset, locate hypocenters, compute b-value and energy.
Flag elevated event rate vs 30-day baseline.
Pick P and S phases; invert for depth trend beneath edifice.
Plot Gutenberg-Richter; track cumulative seismic moment.
Compare depth migration to known conduit geometry.
Shallowing hypocenters with rising tremor suggest ascent.
Maintain a clean workspace throughout — debris causes defects and safety hazards.
Work from coarse to fine — don't skip intermediate steps to save time.
Stop immediately if conditions become unsafe — no project is worth an injury.
