“Early storm surge disaster causes warming” Review of coastal disaster prevention measures October 2:15:51
“When the sea level rises due to global warming, large-scale disasters such as storm surges caused by typhoons occur every year.” In response to the report of the Intergovernmental Panel on IPCC = Climate Change of the United Nations, the Ministry of Land, Infrastructure, Transport and Tourism, etc. will proceed with review of coastal disaster prevention measures.
Typhoon No. 21 last September temporarily observed the highest tide level in the history of observation in Kinki and Shikoku, and Kansai Airport was inundated, causing storm surge disasters in various locations.
Furthermore, the IPCC of the United Nations last month said that when the sea level rises due to global warming, a large-scale disaster that occurs once every 100 years due to typhoon storm surges, etc. will occur every year by about 2050 The report is compiled.
Under such circumstances, the Ministry of Land, Infrastructure, Transport and Tourism established a study group and decided to review the disaster prevention measures for coastal areas.
Until now, coastal disaster prevention measures were planned based on cases of large-scale disasters such as storm surges that were actually in the past, but in the future, we will also consider the effects of predicted warming .
Predict how much the risk of storm surge will increase in the coastal area when the global average temperature rises twice compared to before the industrial revolution, and how to reflect it in the height of the coastal levee to be designed and how to use the land I am thinking.
In addition, many coastal dikes nationwide were developed after the Isewan Typhoon that caused more than 5,000 victims due to massive storm surge damage in 1959. More than 50 years have passed since it was developed in 2035. What will become will be 70% of the total, and we will also consider countermeasures against aging.
