No the Moon and planetary bodies are not able to influence human behaviour, so shut up astrologists and full-moon fever theorists. They can only exert tiny forces, and thus can only be blamed for causing little things such as major earthquakes…
An almost-full, half-pie, waxing moon hanging lopsided in the night sky has long been a symbol of things to come. Now scientists have a new symbolism for the lunar phase we call first quarter: a looming risk of earthquakes.
…Studying data from the past two decades, Satoshi Ide and colleagues from the University of Tokyo measured the timing of high tides and reconstructed the amplitude of the moon’s pull at those times, focusing on the two weeks prior to large earthquakes. They measured the amplitude of the tides against the timing of those quakes, and found some of the largest and most devastating earthquakes in recent memory happened when the Earth’s crust was under the highest tidal stress.
…The mechanisms underlying this connection are not clear, however. The moon’s pull causes tidal disruptions that are orders of magnitude lower than those experienced in an earthquake. And not every change in tide comes with an attendant earthquake. Part of the problem is that scientists still don’t know exactly what causes a major earthquake. But one theory holds that they begin as smaller fractures that build up via a cascading process.
