Earthquake Watch

Q: How do I know the Earthquake Watch output is good?

The skill verifies itself against its own quality checks: The direct yes/no answer leads before any table; Depth appears next to magnitude on every quoted event; Times are converted to the user's local zone with the relative offset; Regional questions used radius filtering, not eyeballed global feeds.

🔵 Stable🕐 updated 2026-07-18 🔷 SkillSpec L3 pm-live

Check recent earthquakes worldwide with zero API keys — USGS real-time GeoJSON feeds via curl, filtered by magnitude, region, and time window. Use when asked was there an earthquake just now, recent quakes near a place, any big earthquakes today, or monitor seismic activity somewhere. Produces the matching events with magnitude, depth, location and time, the felt/damage context bands, and the rerunnable command — with the official-guidance line safety questions require.

What to give it

▸Where — a place to filter around (the feeds are global; lat/lon of the place makes distance filtering honest)

▸The window — "just now" (past hour feed), today, this week

▸The threshold — significant-only vs. everything-they-can-feel (M2.5+) vs. research-grade (all)

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓The direct yes/no answer leads before any table

✓Depth appears next to magnitude on every quoted event

✓Times are converted to the user's local zone with the relative offset

✓Regional questions used radius filtering, not eyeballed global feeds

✓Safety-shaped questions route to official sources by name

⚠️ What it refuses to do

Do not answer from memory — seismicity is the definition of live data; fetch or hand over the command

Do not quote magnitude without depth — half the felt-intensity story

Do not predict aftershocks or all-clears — that's official-agency territory, linked not imitated

Do not present the global significant feed as "nothing near you" — filter by place before saying no

Do not dramatize small events or shrug at large ones — the bands calibrate the tone
