Tsunami Early Warning

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.

***** Unlike some other services which just broadcast generic, ocean-wide tsunami warnings, this one actually calculates wave propagation up to YOUR coordinates. It sends alerts ONLY if location you are in is on the way of a dangerous tsunami wave.

***** Your phone does not have to be online to receive alerts as they are being sent via SMS.

***** You will not get an alert if your location was calculated to be safe. False positive alerts can ruin a good vacation, so the whole purpose of this app is to send alerts ONLY if tsunami actually can reach your shore.



Victims of the 2004 Indian Ocean tsunami could have had up to an hour to leave the shores, if they knew that the wave was approaching. Over 230,000 people in Indonesia, Sri Lanka, India, Thailand, Somali, Maldives, Seychelles and other countries died.
