Movement over the disaster waste management

Items \ Assumed Earthquake Name	“Nankai-Trough Large- scale Earthquake” (Regional scale/large earthquake/tsunami)	“Tokyo Inland Earthquake”
Characteristics	Extensive damage caused by Tsunami (in 24 Pref.) Generation of mixed waste and contaminated waste Difficult to secure the transportation routes, temporary storage sites and disposal facilities for disaster wastes	Enormous amount of disaster waste is generated in the narrow region and capital function is paralyzed. Early waste disposal is needed for recovery of capital functions Loss of waste-related central functions
Magnitude	M 9.1	M 7.5
The probability of occurrence of less than 30 years	Tonankai Earthquake 70～80% Nankai Eathquake 60%	70%
Maximum seismic intensity	7	7
Main disaster areas	Tokai, Kinki, Chugoku, Shikoku, Kyushu Region	Ibaraki, Saitama, Chiba, Tokyo, Kanagawa, Shizuoka Prefectures
Number of estimated evacuees	Max. approx. 9.5 million	Max. approx. 7 million
Estimated amount of disaster waste (Comparison with Great East Japan Earthquake)	Max. approx. 320 million tons (Approx. 16 times)	Max. 110 million tons (Approx. 5 times)
	Note: In the future, a specific scenario for the earthquake that should be considered will be organized, and the amount of disaster waste generation will be estimated, taking into account the characteristics of the regional blocks (organized by prefectures and municipalities units).
¹⁾Estimated amount of tsunami deposit	Max. approx. 27 million tons	-
