Detached breakwaters, made with wave-dissipating concrete blocks such as Tetrapods, have been widely applied in Japan, but the effectiveness of such kinds of detached breakwaters on tsunami disaster prevention has never been discussed in detail.
Pumps and other safety systems may also have been damaged in the earthquake, tsunami, or subsequent meltdown prevention efforts.
Researchers have focused their efforts on the study of disaster prevention from tsunamis, especially with seawalls, e.g. Mizutani and Imamura (2000), Asakura et al. (2002) and Kato et al. (2006).
Areas of practical application include coastal defense against tsunami inundation, harbor protection and erosion prevention with submerged breakwaters, and the construction and design of artificial reefs to use for recreational surfing.
UN Consolidated Flash Appeal [pdf] The overriding health needs for the tsunami-affected region will be directed at the prevention and treatment of malaria, water-borne diseases (cholera, dysentery, diarrhoea), measles, tetanus, and acute respiratory diseases.

Additionally, coastal areas of Miyagi prefecture have been repeatedly hit by huge tsunamis at intervals of several decades (i.e., at 1896, 1933, and 1960) [ 33], and people were culturally prepared (people of the area sustained effort to instill a culture of resilience and prevention based on continuous learning) to cope with tsunami disasters [ 34].
