  2. LIGHTNING: IGNORE AT YOUR OWN PERIL AT THIS VERY MOMENT, 1,800 THUNDERSTORMS ARE HAPPENING SOMEWHERE ON EARTH

  3. LIGHTNING • Every year, the Earth experiences an average of 25 million lightning strikes during some 100,000 thunderstorms.

  6. BOOKS OF KNOWLEDGE Are “TOOLS” that decisionmakers can use to facilitate the minimization of the likely impacts of lightning through public and professional educational programs.

  7. THE PHYSICS cumulonimbus clouds negative charge in the cloud - - - - - - creates positive charge on ground air to ground elect-rical circuit - - - LIGHTNING - - - creates a bolt of lightning reaching - - - DISASTER LABORATORIES - - -50,000 degrees F traveling at 100+ kph

  8. THE IMPACTS 2,000 deaths/yr globally 200 deaths/yr In USA Florida—deadliest state Probability of death: 1:2,000,000 LIGHTNING 71 % have survived when struck DISASTER LABORATORIES Survivors live with- - - physical and psycho-logical problems
