The explosion left a 13-foot deep crater in the middle of a cornfield.
An explosion shook the German town of Ahlbach in the early hours Sunday, leaving a crater 10 meters (33 feet) wide and 4 meters (13 feet) deep in a cornfield. The Associated Press reported that it was likely from a World War II-era bomb. No injuries were reported from the incident.
Town residents told CNN that they were awakened at around 4 am by a loud blast, which was followed by an earthquake-like tremor. According to an official statement from the town of Limburg, investigators discovered a large crater in the cornfield.
Although some believe the blast could have been caused by a falling meteorite, experts determined that the crater was "almost certainly" a World War II bomb, hessenschau.de reports.
The findings are backed by Limburg’s statement, which points out that the Nazis operated railway facilities and radio stations nearby, making the area a target for frequent bombing raids during the war.
Experts told CNN that undiscovered bombs may explode when their detonators deteriorate over time. In fact, unexploded ordnance continue to be found in Germany, even after 70 years after World War II ended. Of instance, TheLocal.de reported that over 2,500 people were evacuated from an area just outside Frankfurt when two World War II-era bombs were found on Monday.
