The system evaluates collected earthquake data from several reliable sources. Based on this information, the Tsunami Alarm System generates an automatic hazard forecast. Our 24/7 team of experienced travel security analysts takes care of the further hazard analysis and the all-clear following an alarm.

If an earthquake has the potential to generate a destructive tsunami due to its magnitude, the depth of the hypocentre and the location (distinction between seaquake and landquake), we send out corresponding tsunami warnings to our subscribers.

For severe earthquakes which are forecasted not to generate a destructive tsunami, e.g. due to their location, we do not send out a notification.
