U.S. Geological Survey Geomagnetic Variometer Data: Capitalizing on Seismic Infrastructure
Year: 2025
Type: article
Abstract: The U.S. Geological Survey’s Geomagnetism Program is collaborating with the Earthquake Hazards Program and Global Seismographic Network Program to densify magnetic field observations. This collaboration focuses on the installation of magnetometers, or magnetic variometers, at existing seismic stations. Along with improving the density of space weather observations for hazard monitoring, these data can be used to correct colocated magnetic field induced noise in seismic data. Such corrections are especially useful during time periods of large magnetic storms where the magnetic field-induced instrument noise can be of similar amplitude to earthquake ground-motion records.
