De liveweergave berekent de gevoelde intensiteit op de draad opnieuw en toont de gebruikte methode en elk afgelezen signaal, zodat het getal kan worden gecontroleerd in plaats van er blindelings op te vertrouwen.

Wiskundig model en methodologie

Atkinson & Wald (2007) intensity prediction equation, SRL 78(3) eq.(1) and table 1: MMI = c1 + c2(M-6) + c3(M-6)^2 + c4*log10(R) + c5*R + c6*B + c7*M*log10(R), R = sqrt(D^2 + h^2). Depth enters as D at the epicentre. Sigma 0.4 MMI units; the regression is well-constrained 10-500 km. Which of the paper's two coefficient sets applies is resolved from the epicentre against the tectonic regions shipped with USGS STREC, the reference implementation of Garcia, Wald & Hearne (2012) BSSA 102(1) that USGS Global ShakeMap uses to select a GMPE (US Government work, public domain). This is a rock-site estimate: it ignores local geology, which commonly moves observed intensity by a unit or more.
