As a novice instructor in the science department at Kumadai, I was asked to critique a graduate student’s presentation and was quite embarrassed when the Japanese professor noted the difference between “reason” and “cause” (science has plenty of causes but no reason) - such distinctions were supposed to be my job, and I determined to be better.
This video reminded me of that long-ago experience: the difference between “hazard” (imminent damage) and “risk” (not so imminent that you need to run away yet) - so I suppose you could say that Aso is a risk but not a hazard. Fortunately, monitors plugged around the mountain measure its swelling due to magma intrusions, so when a “risk” becomes a “hazard,” we will, with luck, be informed. - William
