openquake.hmtk.parsers.strain.strain_csv_parser module

Module: openquake.hmtk.parsers.strain.strain_csv_parser contains the :classes: ReadStrainCsv and WriteStrainCsv to read and write strain data from and to csv format.

class openquake.hmtk.parsers.strain.strain_csv_parser.ReadStrainCsv(strain_file)[source]

Bases: object

openquake.hmtk.parsers.strain_csv_parser.ReadStrainCsv reads a strain model (defined by :class: openquake.hmtk.strain.geodetic_strain.GeodeticStrain) from a headed csv file

Parameters:
  • filename (str) – Name of strain file in csv format
  • strain – Container for the strain data as instance of :class: openquake.hmtk.strain.geodetic_strain.GeodeticStrain
read_data(scaling_factor=1e-09, strain_headers=None)[source]

Reads the data from the csv file

Parameters:
  • scaling_factor (float) – Scaling factor used for all strain values (default 1E-9 for nanostrain)
  • strain_headers (list) – List of the variables in the file that correspond to strain parameters
Returns:

strain - Strain model as an instance of the :class: openquake.hmtk.strain.geodetic_strain.GeodeticStrain
class openquake.hmtk.parsers.strain.strain_csv_parser.WriteStrainCsv(filename)[source]

Bases: object

openquake.hmtk.parsers.strain_csv_parser.WriteStrainCsv writes a strain model (defined by :class: openquake.hmtk.strain.geodetic_strain.GeodeticStrain) to a headed csv file

Parameters:filename (str) – Name of output file for writing
slice_rates_to_data(strain)[source]

For the strain data, checks to see if seismicity rates have been calculated. If so, each column in the array is sliced and stored as a single vector in the strain.data dictionary with the corresponding magnitude as a key.

Parameters:strain – Instance of :class: openquake.hmtk.strain.geodetic_strain.GeodeticStrain
Returns:strain - Instance of strain class with updated data dictionary output_variables - Updated list of headers
write_file(strain, scaling_factor=1e-09)[source]

Main writer function for the csv file

Parameters:
  • strain – Instance of :class: openquake.hmtk.strain.geodetic_strain.GeodeticStrain
  • scaling_factor (float) – Scaling factor used for all strain values (default 1E-9 for nanostrain)
