WebThe Laschamp or Laschamps event [note 1] was a geomagnetic excursion (a short reversal of the Earth's magnetic field). It occurred between 42,200 and 41,500 years ago, during the end of the Last Glacial Period. It was discovered from geomagnetic anomalies found in the Laschamps lava flows in Clermont-Ferrand, France in the 1960s. [1] WebThe Earth's magnetic field (or geomagnetic field) is an ever-changing phenomenon that influences human activity and the natural world in a myriad of ways. The geomagnetic field changes from place to place, and on time scales ranging from seconds to decades to eons. These changes can affect health and safety, and economic well-being. fixlight
