Strong motion flatfiles

For selected large earthquakes, strong motion data have been specially processed, and associated metadata (e.g. earthquake location, parameters describing the recording site) have been compiled into spreadsheets. Common definitions of pseudo-acceleration response spectra have been precalculated and supplied in separate spreadsheets.

Updates since publication are:

  • the addition of the data from the Kaikoura earthquake; and,
  • removal of 25 duplicate recordings from co-located, concurrently recording sensors with different station codes.

For more data products please see the NZSMD webpage.
