Charles Richter (inventor of the you-know-what-scale) was born this day in 1900. In that April is ?National Earthquake Preparedness Month," it's an ideal day to remind you that earthquakes happen anywhere, anytime and without warning. Say ?earthquake? and people think ?California,? but no matter where you live, you need to be prepared. Know where main water and gas shut-off valves are located, and keep a wrench handy. Store three days of drinking water per person and keep bottled water in your car. Keep extra water for pets. Don't put tablets or cleaners in your toilet tanks, you may need that water in an emergency. Secure water heaters and bookcases to a wall and keep a supply of candles, batteries and canned foods on hand. Also have a battery-operated radio for emergency information broadcasts. Don't wait till it's too late. Get going today! And that's the On The House tip for today.
