You may notice a low-flying airplane over the Imperial Valley.

The U.S. Geological Survey says that starting in mid-January 2022 and continuing through Spring 2023, they will be operating the flights to map and model the local geology. According to USGS, the results may help identify the potential for undiscovered geothermal and mineral resources, as well as better understand the geology, hydrology, and potential for natural hazards like earthquakes. The aircraft will carry instruments that measure the earth's naturally occurring magnetic field and radiation - data that will help characterize rock layers at and below the surface. USGS says the instrumentation is passive. It does not emit any signals and poses no health concerns or risks to humans or wildlife. The airplane is operated by experienced pilots who are following all laws.
