New Zealand Earthquake Pictures


This really was an Intensity VIII earthquake in the city.  I would now guess a PGV of 70 cm/s, the same as the highest in Chile.  Lots of liquefaction and probably very high soil amplification.  For an M6.3, if they had accelerometers on the firm ground beneath, the PGV might only be 20-30 cm/s.
