volcanic-check
Check if a speleothem anomaly correlates with volcanic eruptions. Use when ruling out volcanic false positives, checking eVolv2k/VSSI records, or validating seismic interpretations. Triggers on "volcanic check", "eruption correlation", "rule out volcanic", "eVolv2k".

# /volcanic-check - Volcanic Correlation Analysis Skill ## Purpose Cross-reference speleothem anomalies with volcanic eruption records to rule out volcanic false positives. Critical for validating seismic interpretations. ## Usage ``` /volcanic-check <year_CE> [--window YEARS] [--threshold VSSI] ``` **Examples:** ``` /volcanic-check 1275 # Check around 1275 CE (±20 years default) /volcanic-check 620 --window 50 # Wider window for uncertain dates /volcanic-check 1394 --threshold 10 # Only major eruptions (>10 Tg S) ``` ## Volcanic Databases ### Primary Source: eVolv2k The eVolv2k database (Toohey & Sigl 2017) provides: - Volcanic Stratospheric Sulfur Injection (VSSI) in Tg S - Ice core dated eruptions back to 500 BCE - Uncertainty ranges ### Reference Eruptions (VSSI Rankings) | Rank | Year | Eruption | VSSI (Tg S) | Global Impact | |------|------|----------|-------------|---------------| | 1 | 1257 | **Samalas** | 59.42 | Extreme (1258 famine) | | 2 | 1815 | Tambora | 26.03 | "Year without summer" | | 3 | 1452 | Kuwae | 31.06 | Major cooling | | 4 | 1230 | Unknown | 23.78 | Significant | | 5 | 1108 | Unknown | 19.16 | Significant | | 6 | 1809 | Unknown | 22.10 | Pre-Tambora event |

What does the volcanic-check skill do?
Check if a speleothem anomaly correlates with volcanic eruptions. Use when ruling out volcanic false positives, checking eVolv2k/VSSI records, or validating seismic interpretations. Triggers on "volcanic check", "eruption correlation", "rule out volcanic", "eVolv2k".
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill volcanic-check --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
