    • Cross braces
    • Tuned mass dampers
    • Base isolators
    • Lava diverters

  12. If vulnerability increases while hazard and coping capacity stay constant, how does risk change?

    • Mitigating the event
    • Mitigating vulnerability
    • Mitigating losses
    • Community preparedness
