It's unfortunate to see a lot of people online taking seriously the pronouncements of conspiracy theorists and psychics.
If you really want to understand earthquakes, how they form, why they form, and how to prepare for them, you get your information from seismologists, geophysicists, and geologists. They are the scientific experts on earthquakes.
Omens, superstitions, predictions by self-proclaimed psychics, opinions by people who have zero backgrounds on seismology/geology, and conspiracy theories are all just noise. They are not data-based or science-based.
Treat earthquakes like you treat typhoons or storms. If you want to understand typhoons, how they form, and why they form, you get your information from atmospheric scientists like meteorologists and climatologists. Same with earthquakes. If you want to learn about earthquakes, the scientists who study them should be your sources of information.
Superstitions and conspiracy theories are interesting and they make for fun conversations but that's all there is to them. They're good for entertainment. But bad for understanding how the natural world actually works.
You want to be prepared for The Big One? Then listen to what the scientists have to say. Not to the unsubstantiated predictions from conspiracy theorists and self-proclaimed psychics.
