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

Earthquake monitoring:

USGS (U.S. Geological Survey) — global coverage

KMA (Korea Meteorological Administration) — South Korea

JMA (Japan Meteorological Agency) — Japan

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.
