# Measuring Magnetic Field Fluctuations

Posted 11 years ago
 Hi everybody! For this year's science fair project, I want to figure out how to predict earthquakes. I did a lot of research, and so far, I have found out that many earthquakes occur after magnetic field fluctuations within the earth. I actually came across a theory that fluctuations in the Earth's magnetic field might occur hours or even days before an earthquake. In order to test this, I want to create a Wolfram Mathematica program that can detect changes and fluctuations in the magnetic field.  I want to be able to put in the initial conditions of earth, and then I want to be able to generate a graph or a display of Earth's magnetic field at that moment. By analyzing the model, I can find the fluctuations in the graph, and I can predict earthquakes from the fluctuations in the magnetic field. I got my idea from this person: Sensing Danger by Ananya Mukundanand I want to be able to create a program that could recreate a model. Does anyone know how to extract data about magnetic fields from Mathematica? Or can anyone help me with writing this program? Thanks

 This is a big research project.  For a school science fair project, would just a demonstration of the idea be enough? Think about breaking the project into sections: a) obtain accurate measurements of the Earth's magnetic field over a long time for many locations where earthquakes have happened, b) mark when earthquakes happened, and look for similar changes in the magnetic field measurements before eathquakes in different places, c) write a Mathematica code that filters data for that sort of change. The data for (a) is probably available, but you might have to write a lot of letters asking how to obtain copies. The author of the paper at http://cty.jhu.edu/imagine/docs/Sensing_Danger.pdf might be willing to give suggestions, or the references at the end might point to web sites with it. A lot of people are working on (b) already. A demonstration of (c) might be enough.  Take sample data from a paper and show how you could look for unusual changes.
