Volcanology advances since Pinatubo 1991 push toward true eruption forecasting
The article revisits the 1991 Pinatubo eruption, when scientists deployed instruments that detected volcanic unrest and issued an evacuation order shortly before a massive explosion killed over 800 people, saving hundreds of thousands more. It notes that despite this success, the forecast was largely an educated guess rather than a precise prediction, and that volcanology has since improved through better instrumentation and machine learning.
