A powerful earthquake in Chile defied expectations. The magnitude 7.4 quake struck northern Chile near Calama in July 2024. Scientists now believe a hidden, deep-seated force supercharged the event.

The quake originated deep within the Earth. It tore through unexpectedly hot rock layers. This triggered a rare chain reaction, accelerating the rupture. The University of Texas at Austin led the research. Their findings challenge long-held assumptions about deep earthquakes.

The shaking damaged buildings and disrupted power. The earthquake's unusual strength surprised experts. It highlights the complexity of seismic activity.

Chile is earthquake-prone. In 1960, it experienced the largest earthquake ever recorded. That magnitude 9.5 event caused a devastating tsunami.

Researchers are now studying the implications. Understanding this new heat-driven force is crucial. It could improve future earthquake predictions. This discovery may reshape our understanding of deep-earth processes.
