Mount Semeru Unleashes Pyroclastic Flows Stretching 4.5 Kilometers

Mount Semeru's pyroclastic flows represent a natural upheaval/geological crisis. This matches P25 (Famines, Pestilences, and Earthquakes) which describes ecological and geological crises multiplying as birth pangs before the end times, though volcanic activity is a secondary manifestation of the broader category of natural upheavals.
