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 underground force supercharged the event.
The quake ruptured far deeper than typical Chilean earthquakes. It tore through hotter rock layers than previously thought possible. This unexpected rupture was fueled by a rare, heat-driven chain reaction. The University of Texas at Austin led the research.
The shaking damaged buildings and disrupted power. The earthquake's unusual depth amplified its impact at the surface. Researchers are now re-evaluating models of deep earthquake behavior.
Chile is prone to major earthquakes. In 1960, the country experienced the largest earthquake ever recorded, a magnitude 9.5. This new discovery highlights the complexity of seismic events.
Future research will focus on identifying similar hidden forces. Understanding these mechanisms is crucial for improved earthquake prediction. This could lead to better risk assessment and preparedness strategies worldwide.
