How to read this
- Live: the USGS feed was synchronised successfully within the last 20 minutes.
- Degraded: no successful sync for 20–120 minutes; recent events may be missing.
- Stale: no successful sync for over 120 minutes; treat the data as out of date and check the USGS map directly.
- The circuit breaker pauses requests to USGS after repeated failures, then retries automatically.
