(2) When mild disasters occur, southern part Myanmar, western Thailand, northeastern faced large threats; when moderate central eastern Cambodia, comparatively high-loss areas mainly concentrated Vietnam. (3) Considering hazards comprehensively, high-risk distributed central–southern Vietnam, bordering Cambodia Vietnam; medium-risk Sichuan China; speaking, other have lower risk level. This can provide references regions scarce technical support prevention control well
