One might ask what in the world do magnetics have to do with volcanos... and what I learned today is, a lot! I spent the large majority of today walking trails in the Masaya crater and taking magnetic readings every 50 meters. In this picture, you can see me holding the magnetometer, which reads changes in the earth's magnetic composition. When you find a change in magnetics, this indicates that a fault line or fracture is likely below the surface. And why does this matter?? Interestingly enough, the scientists who have been working at the Masaya volcano (some since 1993!) have hypothesized that a system of cones (kind of like baby volcanoes, but they currently look like hills) and fault lines are actually comprised in the larger masaya crater, which could eventually lead to changes in activity and geography at some point in the future.
