It’s always good to take a little time and plan ahead, just in case. When I lived in Japan, I took to heart the earthquake disaster plans, drills, and training. That’s where I honed my bugout bag skills, including bags in the car and at work, and I started putting away precious metals. I refreshed my camping skills and equipment. I also studied maps of the local area for backroads, bottlenecks, and footpaths.
It would be wise for all foreigners in South Korea to start thinking ahead about what they would do in an emergency.
They should gradually discourage people from making non-essential trips and encourage people to leave. It would also substantially reduce political panic domestically when evacuation does occur.
