The “supermoon” is supposed to occur on March 19 I believe. We shall see.
One possible analysis....
The supermoon is optimum, i.e. max gravity.
The earthquakes now show that as the gravitational pull grows failure occurs at a point of lesser stress than when the force is at a maximum, supermoon
It was to be expected as an unpredictable possibility. It was not predictable because the failure stress is unknown and can’t be calculated.
Next time, a prediction can be made on the basis of time before supermoon
