>>One short term fix, especially if your apartment has a balcony and your apartment manager

When the Northridge Quake hit I used my camp stove. I had several gallons of fuel, which could have lasted about a month.
Fortunately, gas and electric were back on in a day or so.
That's really the thing about prepping. If you prepare for bigger things, when small events come along, you can still continue with your day as if very little happened. You don't have to face the mad rush to the grocery store when an ice storm or hurricane is predicted. If you happen to have six months worth of supplies and the power goes out for a week (such as in a big ice storm), those supplies can also be used to help neighbors and family.
