New event visibility
New live events can be focused on the globe and highlighted in the Pulse log without forcing a full alarm.
Alerts and safety signals
Understand how Pulse shows new events, nearby alerts, and tsunami risk.
Pulse separates live visual updates, browser notifications, alarm sounds, and location-based emergency alerts. This helps reduce duplicate alarms while still surfacing the newest significant earthquake activity on the globe and in the Pulse log.
Browser notifications
Pulse can use browser notifications and push notifications when the site is opened with the right permissions.
Tsunami flags
When a nearby earthquake carries a tsunami flag, Pulse can render a risk flag on the globe for the expected window.
Alarm sound control
Choose a sound profile, volume, and alert threshold so alarms are useful without becoming noisy.
How Pulse alerts differ
A live Pulse update is not always the same as an emergency alert. Pulse can show a new earthquake or volcano event on the globe, record it in the log, and only escalate to stronger warning behavior when the event meets the configured threshold or affects your current location.
- Use the alarm threshold slider to limit which events can trigger sound or browser alerts.
- Keep tsunami flags enabled if you want extra map context for nearby tsunami-related earthquakes.
- Review the alert center in the app to see the latest live alert entries in one place.
