Ana Petrovic, a schoolteacher from Karlovac, recounted the moment the earth trembled beneath her feet with trembling lips decades later: “The room danced, the children screamed and clung to me. Our world was tilting, and yet I held onto them—our fragile shield against the chaos.” Such personal narratives breathe life into the statistical damage, reminding us that behind every cracked façade lay human hearts pounding with fear and hope.
8. The Human Toll: Casualties, Injuries, and Displacement
Though the casualty count was relatively moderate—estimated at around 120 dead and hundreds injured—the psychological scars were deep. Entire families lost homes, livelihoods were uprooted, and many faced harsh winters in makeshift shelters. The population displacement altered the demographics of the valley, with some never returning to their ancestral lands. Hospitals in Zagreb overflowed, while volunteer networks from neighboring towns poured in aid, illustrating both the fragile vulnerability and the enduring solidarity of the communities.
9. Emergency Response: How the City of Zagreb and Villages Mobilized
Within hours of the quake’s first violent jolt, the municipal government of Zagreb sprang into action. Makeshift shelters were erected in city parks, emergency medical teams dispatched, and food supplies coordinated. The Austro-Hungarian Empire’s regional authorities dispatched engineers and soldiers to assist. Yet logistical challenges abounded—the rugged terrain, damaged infrastructure, and limited technology slowed relief efforts. Still, the spirit of cooperation among ordinary citizens became one of the most striking elements in this natural disaster’s unfolding drama.
10. Scientific Investigation: Early Seismologists Enter the Field
The Zagreb Kupa Valley earthquake piqued the interest of early 20th-century seismologists who were beginning to unravel the mysteries of the earth’s tremors.
