I am going to take it as a given, that the people who think HAARP can affect the weather or cause earthquakes, have failed Physics II, and have no
background in electronics or radios.
Seriously, HAARP can do neither of those things.
You can look it up. Open a Physics II book, read the parts about conductors, electromagnetism and electron shell theory.
Note the important parts where it says that the electrons can only travel on the surface of a conductor.
Note: that the Earth itself is a huge conductor.
Learn the fact that electricity can only travel so far into the ground, due to the fact that the earth is a conductor.
Look up lighting strikes and the results of what they do to the ground, and how the energy is displaced.
Open a basic book on radio electronics and signal propagation.
Read it, and learn how far signals can travel and how much power is required to accomplish it.
Pay attention to atmospheric conditions and how they effect transmission.
Note the required power in watts to do so.
Then if you really want to get into it, pick up a book on high frequency electronics and high energy physics.
Then you can see the really cool stuff about electron tunneling and how they need super cooled materials to achieve it.
