“8.0 to 9.2 is 16x, not 80x.”
It is 70-80x more energy release. Regardless of 16x vs 80x, which we can debate all day long, a 9.2 subduction quake in the water is far more deadlier than that the 8.0 strike-slip quake on land. There is no debating that.
Can’t argue with that. No matter how you slice it, 9.2 is huge, especially as you say subduction in the water.
109.2 = 1,584,893,192.4611134852021013733915
Almost 16 times greater.
