Implications of the 2011 Great East Japan Tsunami on sea defence design

Introduction In 2011 Japan was considered to be the best prepared nation on earth to withstand a large tsunami attack on its coasts, with sea defence structures (breakwaters, sea dikes and seawalls) specifically designed to afford sufficient protection to coastal settlements and critical infrastructure. Massive detached breakwaters were built in bays to defend great industrial ports and their populations; sea dikes were constructed along much of the coastal plain areas to protect low-lying agricultural land and towns from both tsunamis and storm surges; and seawalls, some of which were 10 m or more in height, were built as a result of previous tsunamis to provide protection for busy settlements.

However, the size of the waves generated by the unexpectedly large magnitude of the 2011 Great East Japan Earthquake (Moment Magnitude 9) led to sea defences and other coastal structures being overwhelmed and in many cases completely or partially destroyed. 2.

Just before 7am on September 29, 2009, a magnitude 8 earthquake struck the sea floor in the central South Pacific, about 190kms south of Samoa.

What happened in the 2009 South Pacific earthquake-tsunami disaster?

It was exactly the sort of earthquake – in fact, it was two almost simultaneous quakes – that create devastating tsunami. The Earth’s crust tore apart, triggering a region-wide tsunami. Within minutes it inundated Samoa’s coastline, before rolling on to American Samoa and Tonga. Read more: Explainer: after an earthquake, how does a tsunami happen? While a tsunami warning was issued by the Pacific Tsunami Warning Center and relayed by Samoan officials, it was not rebroadcast everywhere. Ten years on from this tragedy, it’s time to look back at the lessons we learned – and how they can help us adapt to a rapidly changing climate, which is making similar natural disasters more and more likely.

Image copyright Robert Nickelsberg/Getty The last time a major tsunami hit the Caribbean region was in 1946, after an 8.1-magnitude earthquake struck the Dominican Republic on the island of Hispaniola.

Complacency kills: Caribbean gears up for tsunamis

At Playa Rincón, the sea rushed 700m (2,300ft) inland, according to a man who clung to the top of an almond tree to survive. Waves were 5m high in places and 1,600 people died across the north-east coast. Small tsunami waves were also recorded in Puerto Rico, Bermuda and even New Jersey. Since then, a handful of tsunamis have occurred - in Panama and Costa Rica in 1991 after an earthquake, and in Montserrat in 1997 after a landslide of volcanic debris. Over the same period, populations have more than doubled and tourist numbers on Caribbean beaches have soared, passing 30 million in 2017.

Experts warn that the region runs the risk of complacency over the tsunami threat. Multiple risks. After the Palu and Lombok disasters: a new chapter of disaster governance in Indonesia? Two recent major disaster events in Palu in September and Lombok in August have tested current disaster risk governance in Indonesia.

After the Palu and Lombok disasters: a new chapter of disaster governance in Indonesia?

Thousands of people were killed and displaced as a result of these disasters. The scale of the impacts in both locations shows that effective governance to achieve disaster risk reduction (DRR) before disaster comes remains a challenge. Are we doing it the right way? Tsunamis cannot be averted, but they can be predicted so people can escape. Early warning and disaster prevention and preparedness are paramount. #TsunamiDay.

NOAA Mitigates the Impact of Killer Waves  

But we knew we needed to do more in training, exercise and raising public awareness. In 2009, NOAA and our partners, including the American Samoa Department of Homeland Security (ASDHS), reached out to educate the community about preparing for a local tsunami threat. In the worst case, there would be only 10-15 minutes before the first wave attacked. People needed a response plan and to know how to self-evacuate. Schools located along the shoreline were especially vulnerable. Luckily, ASDHS planned a tsunami evacuation exercise on September 27, 2009 for Matatula Elementary School in Tula village. On September 29, a radio communication exercise was planned for the main port of Pago Pago, and VHF radios were distributed.

These two themes come together in the Japanese story "Inamura no Hi", which tells how a farmer anticipated the 1854 Ansei Nankai earthquake and tsunami, and saved his fellow villagers by burning his entire rice crop to alert them to the danger. The "Inamura no Hi" story exemplifies the power of knowledgeable citizens to save lives.
