Last week’s earthquake off the coast of Japan brought to mind the devastating earthquake and tsunami that slammed into the island nation in 2011. While this earthquake caused relatively little serious damage, and thus becomes just one of many earthquakes to hit Japan over the year, there is one point that is particularly noteworthy: residents were warned a full six minutes before the earth shook.

The exercise will include sending test messages via electronic mail, fax and the Global Telecommunication System from the Istanbul Observatory and Earthquake Research Institute (KOERI, Turkey) to all the national centres and tsunami warning focal points in the region.

HONOLULU — The warning was ominous, its predictions dire: Oceanographers issued a bulletin telling Hawaii and other Pacific islands that a killer wave was heading their way with terrifying force and that “urgent action should be taken to protect lives and property.”
But the devastating tidal surge predicted after Chile’s magnitude 8.8-earthquake for areas far from the epicenter never materialized. And by Sunday, authorities had lifted the warning after waves half the predicted size tickled the shores of Hawaii and tourists once again jammed beaches and restaurants.
Scientists acknowledged they overstated the threat but many defended their actions, saying they took the proper steps and learned the lessons of the 2004 Indonesian tsunami that killed thousands of people who didn’t get enough warning.
“It’s a key point to remember that we cannot under-warn. Failure to warn is not an option for us,” said Dai Lin Wang, an oceanographer at the Pacific Tsunami Warning Center in Hawaii. “We cannot have a situation that we thought was no problem and then it’s devastating. That just cannot happen.”
Hundreds of thousands of people fled shorelines for higher ground Saturday in a panic that circled the Pacific Rim after scientists warned 53 nations and territories that a tsunami had been generated by the massive Chilean quake.
It was the largest-scale evacuation in Hawaii in years, if not decades. Emergency sirens blared throughout the day, the Navy moved ships out of Pearl Harbor, and residents hoarded gasoline, food and water in anticipation of a major disaster. Some supermarkets even placed limits on items like Spam because of the panic buying.
At least five people were killed by the tsunami on Robinson Crusoe Island off Chile’s coast and huge waves devastated the port city of Talcahuano, near hard-hit Concepcion on Chile’s mainland.
But the threat of monster waves that left Hawaii’s sun-drenched beaches empty for hours never appeared — a stark contrast to the tidal surge that killed 230,000 people around the Indian Ocean in 2004 and flattened entire communities.
This may be a little dated, but it looks like Maldives is implementing cell broadcast technology, in addition the article also mentions about an alert and warning system in Sri Lanka that is in place for a couple of years. The study mentioned in the article – ‘Mobile Cell Broadcasting for Commercial Use and Public Warning in the Maldives’ – is available online here.
Maldives to get early warning alerts via SMS02 September 2009
Facing increased threats triggered by climate change, Maldives will soon receive text based early warning alerts for disasters. Cell broadcasting, a technology will enable delivery of information to multiple users simultaneously in a specified area.
Texting short messages through mobile phones could help in early warning of natural disasters in the Maldives, says a new report.
The technology, called cell broadcasting, helps to deliver messages simultaneously to multiple users in a specified area.
In the case of the Maldives, if an early warning is introduced, it must be able to reach all of the outlying islands including tourists on resorts.
With mobile phones quite ubiquitous, it may be an ideal time to introduce an emerging technology — cell broadcasting — for public early warning,” says the report, ‘Mobile Cell Broadcasting for Commercial Use and Public Warning in the Maldives’, which was published last month (15 July).
