The San Simeon Earthquake

• Dec 22, 2003 - 6.5 Mw, reverse fault, 20km long,
  50 cm maximum offset
• 2 people killed, a new sulfur hot spring

Triggered creep at Parkfield and seismicity in
the Geysers region north of San Francisco

• The animation spans 210 seconds from the origin
  time. The blue and green colors indicate
  different sign of the waves (i.e. up vs. down),
  and the intensity of the color scales with
  amplitude. The wavefield incident to the San
  Francisco Bay Area is dominated by long-period
  surface waves which are then affected by the
  sedimentary basins increasing their amplitudes
  and locally extending the duration.
