Not an official alerting service
SeismicWatch Pro is an independent informational dashboard. It does not replace Wireless Emergency Alerts, sirens, radio, official bulletins, evacuation orders, or local expert guidance. Browser audio notifications are best-effort and may be blocked, delayed, or missed.
Data changes
Earthquake magnitudes, depths, locations, tsunami flags, volcano statuses, and other observations are preliminary and may change. Automated aggregation can introduce delay or error.
