On Wednesday, the 2nd largest earthquake to have ever occurred in Denmark struck, occurring south of the capital city of Copenhagen. This caused the ground to shake for several seconds, surprising the millions of people who felt it. Yet, while some scientists are claiming that this earthquake was caused by a weak zone in the crust known as the "Sorgenfrei-Tornquist zone", I must disagree as in my interpretation as a geologist I think an even older weak zone was to blame. This earthquake occurred on May 20th, 2026. Thumbnail Photo Credit: Google Earth, Image Landsat / Copernicus, Data SIO, NOAA, U.S. Navy, NGA, GEBCO.
