Intense Heat and Wildfires Trigger Unexploded WWI and WWII Munitions Across European Forests

LJUBLJANA, SLOVENIA — Prolonged summer heatwaves and brush fires across historic European battlegrounds triggered secondary subterranean detonations of century-old artillery shells and landmines Saturday, creating severe hazards for wildland firefighters.

Subterranean Ordnance Detonations

In the Karst region along the Slovenia-Italy border, site of the World War I Battles of the Isonzo, military bomb disposal technicians documented over twenty spontaneous explosions caused by intense ground fire temperatures cooking off buried ordnance.

Fire crews were forced to withdraw perimeter hand-lines, relying exclusively on aerial water-dropping aircraft to battle blazes without risking ground personnel casualties.

Legacy Military Hazard Mapping

European civil protection authorities initiated emergency ground-penetrating radar mapping along known World War frontlines to establish safety buffer corridors for forestry workers and local rural villages.
