I guess the movie “The sinking of Japan” is closer than we think, but I really hope that would never happen.
The magnitude 9.0 earthquake that struck Japan caused large parts of Tohoku to sink. In most areas, the ground has only dropped a few centimeters, making the change barely noticeable. However, as this report from Asahi TV shows, some coastal areas have sunk to below sea level, leaving them permanently flooded:
Their reporter visits an area of Ishinomaki city. The neighborhood was spared from the full force the tsunami, but its drop in elevation has left it flooded. Depth of the water changes as the tides come in and out. In one spot, a manhole seems to be sticking out of the ground. Residents originally believed that the earthquake had pushed the manhole out of the ground, but in reality, the ground had sunk and the manhole had remained in place.
One man says he and his family have given up on the first floor of their house. They are living on the second floor. Their dog spends his time on the roof. The water that floods the streets is usually dirty and foul-smelling.
The worst sinking- 84 centimeters (2.75 feet) – occurred in part of Rikuzentakata city. That’s about as tall as a bicycle.
The largest fall of 84 cm was observed in Rikuzentakata, Iwate Prefecture, followed by 78 cm in Ishinomaki, Miyagi Prefecture, said the institute that released the findings of its survey which used the global positioning system.
A drop of 29 cm was also found in Soma, Fukushima Prefecture, it said.
The drops were caused by a sharp movement of plates below the Tohoku region in northeastern Japan due to the magnitude 9.0 earthquake on March 11.
