My wife always has a migraine 24-48 hours prior to an earthquake. Has anyone else ever experienced this?
Wow, I just researched it and your wife is not alone! People all over the world get headaches just before an earthquake!
Perhaps it is related to air pressure or the tension she feels just before. Does it go away after it stops? Does she only get headaches on their occurrence?
I wonder if there is some effect just before an earthquake since they happen so suddenly and instantly. They can measure seismic activity before an earthquake. I wonder if she can feel the slight tremors before and this subconsciously gives her deep tension?
Here is a cool earthquake monitoring site:
