Nearly twenty years ago, satellites orbiting Earth captured a mysterious gravity signal near the coast of Africa. This indicates a rare geological disturbance deep within the planet was happening. This specified signal stretched about 7,000 kilometres across the eastern Atlantic Ocean, although it lasted nearly two years, peaking in early 2007. Scientists mention that it is the result of coinciding with a sudden “jerk” in Earth's magnetic field. In addition, as detailed in Geophysical Research Letters on August 28, both events were linked to a previously unknown deep-Earth process which brings changes in the planet's gravitational balance. GRACE Satellites Reveal Deep Mantle Shift Behind Earth's Mysterious Gravity Anomaly According to study, researchers discovered the anomaly while reviewing archived data from NASA and Germany's Gravity Recovery and Climate Experiment (GRACE) satellites, which measured variations in Earth's gravity between 2003 and 2015. The signal ...
