Always have a tsunami-evacuation plan, always keep an emergency survival kit in your car, know the area, be cautious and react quickly after an earthquake
I always carry a knife for self-defense as it helps that knife laws are less restrictive than those for concealed carry and you won’t get in too much trouble.
The very act of being prepared to protect myself and my family by carrying concealed, also means that I am protecting others who are in that same environment.
