Choose which areas you want to hear about. For a large coastline, you can limit alerts to selected countries, states, provinces, or territories. If you do not choose any areas, you still receive alerts for the whole coastline. Your choices are the areas you pick. Tsunami Watch does not use your GPS location to decide which alerts to send. Location stays optional, for the map and distances. Silence one alert. Mute further updates for a specific event when you no longer need notifications about it.
