A groundbreaking analysis of satellite data has revealed that the catastrophic 2018 eruption and collapse of Indonesia’s Anak Krakatau volcano which triggered a deadly tsunami was preceded by years of subtle but accelerating movements along its mountainside. Researchers at Penn State University found that the volcano's flank had been slipping for over a decade, showing signs that could have potentially served as an early warning if monitored in real time. The study, recently published in Geophysical Research Letters, highlights how advanced radar satellites can detect minute ground deformations, helping scientists track unstable ocean volcanoes and predict possible collapses before they occur. "Ocean volcanoes, when unstable, can collapse catastrophically and generate tsunamis," expl...
