CWarn is a global tsunami warning and alert system. Registration and membership is totally FREE.

CWarn monitors global earthquake activity and alerts registered members, via an SMS text message on their mobile phones, should a tsunami threaten their particular location.

The CWarn system makes use of its member's latitude and longitude, taken from the member's registered location to calculate distance from the earthquake and possible threat levels.

All possibly effected members are sent an SMS message detailing earthquake magnitude, time, date, location and threat level. The system also allows for members to change their location should they be travelling to another location.
