Dormant for over 30 years, Mt Ontake is a popular climbing destination, and at least 250 people were initially trapped on the slopes. At least 30 were killed; most made their way down by Saturday night, but the injured, unable to descend the 10,062-foot mountain on their own, stayed in mountain lodges. Rescue workers had to suspend operations on sunday due to nauxious gases and volcano-induced seismic activity. The keys to resilience: 1) know the eruptive history of your region’s volcanoes,2) be prepared 3) have a warning system 4) evacuate 5) learn from the experience and start over. Technologies for monitoring, forecasting, and warning are vital for survival.
