Ibaraki Prefecture has been constructing a seawall in the coastal area with the aim of completing it by the end of next month, which is 10 years after the Great East Japan Earthquake, but due to the delay in construction, it is virtually impossible to complete it as planned. I found that it was.
Ibaraki Prefecture is in the coastal area from Kitaibaraki City to Kamisu City, which was damaged by the tsunami, and is under construction to raise the embankment and install a new one. It has been 10 years since the earthquake. It was scheduled to be completed by the end of the month.
Currently, only about 5 km is left in Kitaibaraki City and Oarai Town, but it is virtually impossible to complete 1.4 km, which is 30% of this, by the end of next month. I understood from the interview.
Construction has been delayed around the Otsu fishing port in Kitaibaraki city and the Oarai port in Oarai town, and it took longer than planned to restore the port, and discussions with the local community were difficult over the planned construction site. That is the main cause.
The prefecture has a policy of aiming for completion by March next year, and the Prefectural Fisheries Promotion Division says, "Many residents live near the points where construction is delayed, and we want to proceed with the construction as soon as possible."
Residents "maintain quickly"
Right next to the planned site in Otsu-cho, Kitaibaraki City, where the construction of the seawall has been delayed, there are many houses that have been rebuilt after being damaged by the tsunami caused by the Great East Japan Earthquake.
An 80-year-old woman living in this area said, "10 years ago, my home was damaged by the tsunami, and I am still worried that the tsunami will not come again or every time an earthquake strikes. I want it. "
A 39-year-old man who joined the fire brigade in this area said, "Given the possible tsunami in the future, I don't think there should be any delay in the construction of the seawall. There are many elderly people in this area. It takes time to evacuate, so I want the construction to be completed as soon as possible. "
Tsunami inundation assumption more than 3 times that of the Great East Japan Earthquake
Construction of the tide embankment in Ibaraki Prefecture is proceeding based on the tsunami damage estimation in the event of a huge earthquake off the coast of the prefecture, which was compiled by the prefecture in 2012, the year after the Great East Japan Earthquake.
According to it, it is said that a tsunami with a height of 4 meters or more will flood the entire coastal area in the prefecture, and the height of the tsunami is assumed to be 14.8 meters in Kita Ibaraki City and 10.1 meters in Oarai Town, where the construction of the embankment is delayed. It has been.
It is assumed that the tsunami will flood 10 coastal cities and towns with more than three times the area of the Great East Japan Earthquake.
Also, in April last year, a national study group showed the assumption of the height of the tsunami in the event of a huge earthquake in the "Kuril Trench" and "Japan Trench" from off Hokkaido to off Iwate Prefecture, Kitaibaraki. It is said that the height will be 6.5 meters in the city.
Also, in Oarai Town, it is assumed that the government office building will be flooded up to 2.1 meters, and measures against tsunami are an issue in the prefecture.
