A deep earthquake in Chile defied expectations, releasing unexpected energy. The magnitude 7.4 quake struck near Calama in northern Chile in July 2024. Scientists now believe a hidden, heat-driven force supercharged the event.
The earthquake originated deep within the Earth. It tore through hotter rock layers than previously thought possible. This unexpected rupture was fueled by a rare chain reaction. The accelerated rupture defied long-held assumptions about deep earthquakes.
The shaking damaged buildings and disrupted power. The event highlights the complex forces at play beneath our feet. Researchers at the University of Texas at Austin made the discovery.
Chile is earthquake-prone, experiencing frequent seismic activity. The 1960 magnitude 9.5 quake remains the strongest ever recorded. This new finding suggests a need to re-evaluate earthquake risk models.
Future research will focus on understanding these deep-seated forces. Scientists aim to predict similar events in other regions. This could lead to improved earthquake early warning systems.
