   "abstract": "We show that seismic attenuation (\u00a0) along the San Andreas fault (SAF) at Parkfield correlates with the occurrence of moderate\u2010to\u2010large earthquakes at local and regional distances. Earthquake\u2010related\u00a0\u00a0anomalies are likely caused by changes in permeability from dilatant static stress changes, damage by strong shaking from local sources, and pore unclogging/clogging from mobilization of colloids by dynamic strains. We find that, prior to the 2004\u00a0M6 Parkfield earthquake, prefailure conditions for some local events of moderate magnitude correspond to positive anomalies of\u00a0\u00a0on the Pacific side, with local and regional earthquakes producing sharp attenuation reversals. After the 2004 Parkfield earthquake, we see higher\u00a0\u00a0anomalies along the SAF, but low sensitivity to local and regional earthquakes, probably because the mainshock significantly altered the permeability state of the rocks adjacent to the SAF, and its sensitivity to earthquake\u2010induced stress perturbations.",
