Tsunami Early Warning app for iPhone and iPad

Get an early warning if the location you are in is in the path of a tsunami wave. The Tsunami Early Warning app calculates tsunami wave propagation and sends you an SMS message if you are in danger. The message will include estimated time of contact with the wave, giving you a notice of the wave approaching.

Let the service know your location every time you change shores and have your phone around when on a beach to get an early warning.

No data roaming subscription is required for location updates.


The 2004 Indian Ocean tsunami killed over 230,000 people in Indonesia, Sri Lanka, India, Thailand, Somali, Maldives, Seychelles and other countries. After the earthquake happened, tsunami victims could have had up to an hour to leave the shores, if they knew that the wave was approaching.

Install this app to get early warnings.

***** You will not get an alert if your location was calculated to be safe.
Many other Tsunami Alert services use blanket approach, alerting all the shores of, say, Pacific Ocean, from Chile to Japan if an earthquake has happened somewhere. This service calculates wave propagation and sends alerts only for areas which potentially can be affected.

Make sure to install this app if you go to or live in one of the tsunami-prone areas such as Alaska, Thailand, Hawaii, Maldives, Mexico, Indonesia, Philippines, New Zealand, Australia etc.
