Verification details & recent checks

No check completed for this region / period.

These are checks made by this browser, not a server-wide audit. “Same snapshot” is normal while the SMC source cache is valid. No new earthquakes does not mean a broken connection; earthquake origin time is not the feed-update time. Map tile loading and e-mail / Telegram delivery are separate and are not verified by this panel.

Catalogue, not a warning or prediction. Magnitude is not felt intensity. Agency locations and magnitudes may be revised. A USGS tsunami review flag is not an official warning, and AFAD catalogue records do not supply that flag. Official tsunami bulletins ↗ · Existing SMC alarm rules and e-mail subjects are unchanged.
