Just read John's letter questioning the facts in the Radon/earthquakes/ionosphere article, both in EOS. Nicely concise: has 4 sentences only (although long ones). I'd like to hear more about the one part that is "warmly debated" on preparation areas for large earthquakes. What is the debate? How could some place 100s of km away know that a rupture is going to take off? What's the logic?
