Being in a good physical shape can help on a earthquake because if you want to run fast you learned to breath through your nose. Then you need to make a first aid pack which contains granola bars that will be helpful during and emergency event.
The next thing you need is to prepare a first aid kit that contains water, food, bandages, medicine,healthy granola bars, flashlight, batteries, radio. The reason you need a first aid kit prepared is because you don't know when an earthquake,tornado,hurricane will happen.
The first aid kit will help my family because it contains all the important stuff in the first aid kit. It will help because in case anyone in your family gets hurt or a scratch than that's when you will use alcohol to clean the blood and you wrap it up with bandages.
