LaMEVE — Large Magnitude Explosive Volcanic Eruptions Database Intelligence

KBT-LAMEVE-DATABASE-1.0

Core thesis The probabilistic assessment of large explosive eruptions requires a complete, standardized catalog extending beyond the historical record into the geological past — and LaMEVE provides that catalog for events with sufficient preserved deposit evidence to characterize magnitude and timing.

Primary frameworks

  • Eruption Magnitude (M) Scale — log₁₀(mass) standardized magnitude replacing VEI for large-eruption comparison
  • Temporal Completeness Windows — catalog completeness thresholds as a function of eruption magnitude
  • Frequency-Magnitude Statistics for Large Events — power-law distribution of large explosive eruptions
  • Quaternary Eruption Record — extending analysis from historical to geological timescales
  • M vs. I (Magnitude vs. Intensity) — distinguishing total eruptive output from eruption rate
  • LaMEVE-GVP Cross-Reference — linking large-eruption records to GVP volcano identifiers
  • Climate Forcing Threshold Events — identifying eruptions crossing stratospheric aerosol injection thresholds

What this tile gives an agent:

  • Query LaMEVE for large explosive eruption records at specific volcanoes or regions
  • Apply Quaternary eruption magnitude-frequency statistics to long-return-period hazard assessment
  • Calculate recurrence intervals for M≥6, M≥7, and M≥8 eruptions from LaMEVE frequency data
  • Assess temporal completeness limitations for statistical analysis of LaMEVE records
  • Apply LaMEVE data to climate forcing probability assessment for large eruption scenarios

What it extracts

  • Large Eruption Catalog Queries — retrieve M≥4 explosive eruption records from Quaternary to present
  • Magnitude Scale Application — apply M = log₁₀(mass) as standardized alternative to VEI for large events
  • Temporal Completeness Assessment — evaluate catalog completeness windows for statistical analysis validity
  • Frequency-Magnitude Analysis — fit power-law to LaMEVE data for large-eruption recurrence estimation
  • Quaternary Recurrence Intervals — calculate return periods for M≥6, 7, 8 eruptions from geological record
  • M vs. I Distinction — apply magnitude vs. intensity discrimination for large vs. high-rate eruption comparison
  • GVP Cross-Reference — link LaMEVE eruption records to GVP VNUM for volcano-specific analysis
  • Climate Forcing Threshold Events — identify eruptions crossing stratospheric aerosol injection thresholds
  • Long-Return-Period Hazard — apply LaMEVE statistics to 1,000-10,000 year return period hazard assessment
  • Supervolcano Frequency Statistics — derive M≥8 eruption probability from LaMEVE global record
  • VOGRIPA Database Integration — access full LaMEVE dataset with deposit characteristics and references
  • Bayesian Prior Construction — use LaMEVE frequency data as prior for large-eruption probability models
