Our friend Bob Davis has been working on a new version of his DIY Earthquake Detection which monitors magnetic fields to attempt to predict earthquakes. This new design is using UGN3503 hall effect devices and an Arduino.
“I came up with this idea over 10 years ago because animals behave strangely before earthquakes. They know something is about to happen. I also know animals can navigate magnetically. If you put baby sea turtles in a pool they will swim east to west. If you add a magnet the will arc around it. “
