plane integral point setsMore than a century ago, Norman Anning conjectured that it is possible to arrange 48 points on a circle, such that all distances between the points are integer numbers and are all among the solutions of the diophantine equation x 2 + xy + y 2 = 72· 132· 192...
As a result, the ground-motion prediction equation (GMPE) with the PS model underestimates the shaking at stations around the fault but far away from the hypocenter. Consideration of the fault distance into the GMPE will improve the accuracy of the shaking intensity estimation. Fault distance ...
