disaster Stuart Diver has launched an SMS service to warn Australians of an impending tsunami threat to our coastline.

Alert 24-7 will monitor electronic media around the clock for official tsunami warnings and immediately inform subscribers via SMS if such an event poses a threat.

Mr Diver, who recently moved to the South Coast, said all of Australia's coastline was at risk of the massive waves called tsunami.

Some experts, including Wollongong University's Ted Bryant, have said that based on geological evidence, the South Coast could be in the firing line.

A huge block of coral was found 80-metres up a cliff near Jervis Bay leading experts to believe a tsunami had struck the region before, with two main causes being either an undersea earthquake or landslide on the seabed between the East Coast and New Zealand.

Mr Diver said the Alert 24-7 system could also be applied to other natural disasters such as bushfires as well as cyclones.

The Alert 24-7 project commenced after the deadliest tsunami in recorded history claimed 280,000 lives on Boxing Day 2004.

The 'seachange phenomenon' has led to enormous growth in beachside communities, and more than 80 per cent of Australians now live within 50 kilometres of the coastline.

Mr Diver said he was concerned about the lack of an effective warning system in Australia, which would allow residents adequate time to respond to a potential threat.

"I saw that the current system lacked any way of directly communicating with me in the event of a warning being released. Together with a team in Brisbane, I embarked on setting up Alert 24-7 to rectify that problem," he said.

"I personally know the pain and suffering that an unexpected tragedy can have on the lives of all involved.

"Given the large proportion of Australia's population which now lives near the coast and having just moved to the coast myself, I see the importance of a tsunami alert that will warn of impending danger at all hours."

Mobile phone users can subscribe to the service by texting ‘alert' to 191 911 for a joining fee of $4 and an ongoing fortnightly fee of $2. For further information, visit the website www.alert247.com.au
