Imaging Magma Under St. Helens

UPDATED AS OF JULY 4, 2014

Station label colors are a function of the landowner, where green is US Forest Service, dark blue is Weyerhauser, Yellow is National Monument, orange and red is other private land.  There are several station on and near the volcano (marked with little balloons) that are part of the permanent monitoring network.  These will be part of the iMUSH project with their data integrated into the complete group.
