Description
Alerti delivers earthquake and tsunami notifications based on your location, sourced directly from official seismic and tsunami monitoring agencies across the Asia-Pacific and beyond.
DATA SOURCES

LOCATION USE
Alerti requests your location only while the app is open. It is used to compute distance from epicenters and decide which alerts are relevant. Your location is never shared with third parties.
IMPORTANT
Alerti is an informational app. It is not a substitute for official emergency warning systems issued by government agencies, such as J-Alert, ShakeAlert, or national Emergency Alert broadcasts. During a disaster, always follow guidance from local authorities.
