Abstract
We find invariant high stress drops and radiated energies for a sequence of intraplate
earthquakes. We estimate source parameters of the Au Sable Forks, NY earthquake (M5,
2002) and aftershocks. This intraplate earthquake was the largest to occur in Eastern
North America since1988 and the largest to be recorded by regional broadband networks.
We use the Empirical Green's Function (EGF) method, and define a set of qualitative and
quantitative rules for the selection of EGF earthquake pairs and for the quality
