I spoke too soon. The USGS National Earthquake Information Center has posted a PGA map (peak ground accleration) for the Chile earthquake.
This is given as a contour map. Maximum values at the epicenter are about 30% of the acceleration due to gravity, which approaches the 50% shown on the seismic hazard projections of the last two blog entries.
Presumably, the blue dots represent data points from seismographs/accelerographs.
