Place GPS and tilt benchmarks on stable flanks away from active vents.
Record continuous GPS or repeat EDM lines to stable points.
Derive horizontal and vertical motion rates relative to stable site.
Plot cumulative displacement against alert-level criteria.
Report vector components, reference frame, and uncertainty ellipses per IAVCEI guidance.
Take photos at each stage to track progress and troubleshoot if results differ from expectations.
Record settings, measurements, and techniques that produced good results for future reference.
Read material safety data sheets before handling unfamiliar materials or chemicals.
