Mystery anomaly weakens Earth's magnetic field, report scientists

Paul Ratner


Quote:The scientists were able to establish that the entire magnetic field of the planet has diminished by 9 percent in its strength during the past 200 years. The "South Atlantic Anomaly" segment, which stretches from Africa to South America, is of particular concern. Satellites from ESA's Swarm Constellation mission, that looked into the anomaly detected a strong weakening southwest of Africa, which points to the possibility that the area would break into two different low points.

While the observed changes don't necessarily mean the Sun is about to fry our planet or some similar calamity, it does indicate that something is happening within the Earth's core. This is what the agency is hoping to figure out through further research. One possibility – the north and south poles are about to switch positions, with the South Atlantic Anomaly being the origin of the transformation (which happens every 250,000 years or so).

Quote:Jürgen Matzka, a researcher into geomagnetism at the GFZ German Research Centre for Geosciences, explained in a statement that the new weak spot "has appeared over the last decade and in recent years is developing vigorously." He added that we're fortunate to have the Swarm satellites studying the issue, while "the challenge now is to understand the processes in Earth's core driving these changes."
