verify-dark
Verify dark earthquake claims against fault databases. Use when checking if a candidate earthquake is truly "dark" (unmapped fault) or just pre-historical (known fault). Triggers on "verify dark", "check fault database", "is this dark", "audit earthquake claim".

Same command for any agent — swap --agent for codex, cursor, copilot.

# /verify-dark - Fault Database Verification Skill ## Purpose Verify if a candidate "dark earthquake" claim is truly dark (unmapped source fault) or pre-historical (known fault, no written record). This skill automates the DARK_EARTHQUAKE_AUDIT.md workflow. ## Usage ``` /verify-dark <lat> <lon> <date_CE> [region] ``` **Examples:** ``` /verify-dark 44.2 8.1 1394 italy /verify-dark 32.7 -117.2 1741 california /verify-dark -16.5 -44.8 96 brazil /verify-dark 22.4 -84.0 1400 caribbean ``` ## Workflow ### Step 1: Identify Region & Databases Based on coordinates, determine which fault databases to check: | Region | Primary Database | Secondary Databases | |--------|-----------------|---------------------| | **Italy** | DISS v3.3.1 (INGV) | ITHACA, EFSM20, GEM SHARE | | **California** | SCEC CFM v7.0 | CGS FER, USGS Quaternary | | **Caribbean/C. America** | GEM CCAF-DB | USGS | | **Brazil** | GEM SARA | (Note: Brazil EXCLUDED from SARA) | | **Middle East** | EMME | GEM, Hessami (2003) | | **Romania** | RODASEF | ESHM20, SHARE | | **Turkey** | AFAD | GEM, Emre et al. | ### Step 2: Search Fault Databases For each database, search within 50km and 100km radius: 1. **Use calc_distance MCP tool*

What does the verify-dark skill do?
Verify dark earthquake claims against fault databases. Use when checking if a candidate earthquake is truly "dark" (unmapped fault) or just pre-historical (known fault). Triggers on "verify dark", "check fault database", "is this dark", "audit earthquake claim".
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill verify-dark-drsatsuma1-speleoseismology --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.
