Tsunami Shield

Tsunami Shield helps you monitor tsunami warnings and earthquake activity for the places that matter—your home, your family’s locations and your travel destinations.

Stay informed with location-based alerts, a live global activity map, evacuation guidance and emergency contact features. Designed for coastal residents, travellers and families who want to understand activity near home and abroad.

HOME AND FAMILY MONITORING

• Home location monitoring — receive tsunami alerts relevant to your home location.

• Saved Locations — monitor important places, including family homes, friends’ cities and destinations you want to follow.

• Home Country Protection — GPS-aware alerts when a warning is issued in your home country.

TRAVEL WITH MORE INFORMATION

• Travel Mode — add countries you are visiting to receive relevant alerts while abroad.

• Global Watch — select countries you want to monitor for tsunami and earthquake activity.

• Destination Safety Check — check whether your destination country has active tsunami watches or warnings before you travel.

ALERTS AND GLOBAL ACTIVITY

• Follow tsunami alert status changes, including Watch, Advisory, Warning and All Clear, as available from monitoring sources.

• Explore the Globe — view tsunami and seismic event markers and regional alert status on a live global activity map, refreshed every 15 seconds.

• Recognise urgent notifications with a distinct warning siren.

• Receive push notifications when your phone is locked or the app is not open, subject to connectivity, permissions and device settings.

Where supported and enabled, urgent alerts can sound through silent mode or Do Not Disturb. Notification delivery, sound and screen behaviour depend on your Android device, permissions, battery restrictions and settings.

EVACUATION AND EMERGENCY ASSISTANCE

• Access mapped evacuation route guidance with step-by-step directions.

• Notify your emergency contacts that you are safe or need assistance, with your GPS coordinates included.

Evacuation guidance is a supporting tool, not a guarantee that a route is safe or accessible. Always follow local authorities, evacuation signs and current conditions.

MONITORING SOURCES

Tsunami Shield uses information from NOAA, PTWC, GeoNet, JMA and other monitoring agencies. Available information and alert coverage depend on the location and reporting source.

IMPORTANT SAFETY INFORMATION

Tsunami Shield does not predict earthquakes or tsunamis. Earthquake monitoring and alerts should not be interpreted as a guarantee of warning before shaking begins.

An internet connection is required to receive updated monitoring information and push alerts. Information and notifications may be delayed or unavailable.

Do not wait for an app notification if you experience natural tsunami warning signs, such as strong or prolonged shaking or unusual sea behaviour. Follow official warnings and local evacuation instructions immediately.

Tsunami Shield supplements—not replaces—official emergency warning systems and advice.
