We monitor the Earth's magnetic field. Using ground-based observatories, we provide continuous records of magnetic field variations; disseminate magnetic data to various governmental, academic, and private institutions; and conduct research into the nature of geomagnetic variations for purposes of scientific understanding and hazard mitigation.
Research projects within the USGS Geomagnetism Program are targeted for societal relevance, especially for space-weather hazard science.

Budget Focuses on Core USGS Science and Efficiency
While major geomagnetic storms are rare, with only a few recorded per century, there is significant potential for large-scale impacts when they do occur. Extreme space weather can be viewed as hazards for the economy and national security.
New strides have been made toward quantifying how geomagnetic storms can interfere with the nation’s electric-power grid systems.
September is National Preparedness Month, a time to highlight the resources available to help you and your loved ones stay as safe as possible.
Magnetic storms can interfere with the operation of electric power grids and damage grid infrastructure. They can also disrupt directional drilling for oil and gas, radio communications, communication satellites and GPS systems.
