After the Deluge: Tsunami and the Great
Wall of Japan
Like hundreds of communities along
Japan's northeast coast, the village of Koizumi exists on maps only. On 11
March 2011, an M9.0 earthquake beneath the Pacific Ocean erupted with the
force of a million tons of TNT, triggering towering waves that killed
around 19,000 people. In Koizumi, 40 of the 1,800 villagers died.
Fear of another giant tsunami has spurred elaborate government
plans to build 440 concrete walls and breakwaters along 230 kilometres of
coastline in the worst-hit prefectures of Fukushima, Miyagi and Iwate. The
seawall solution is controversial, not only because the evidence for their
effectiveness is mixed, the cost is enormous, and seawalls may not address
the needs of relocating local communities. This article, introducing the
voices of tsunami victims, officials and scientists, presents the most powerful
arguments for and against the construction of seawalls in the devastated
areas. Is the hope of future safety worth the cost of rebuilding Japan's
coastal communities as "concrete fortresses"?
