M-logA Observations for Recent Large Earthquakes

Abstract Using a magnitude ( M )-log area ( A ) dataset augmented with seven large ( M >7.0) earthquakes occurring since Wells and Coppersmith (1994), this short note assesses the current validity of the bilinear M -log A relations for continental, strike-slip earthquakes proposed by Hanks and Bakun (2002), in particular the L -model scaling at M >7. The relations determined by Hanks and Bakun (2002) are only insignificantly altered, leaving these bilinear M -log A relations as valid now as when first proposed.
