Submodules

seismic.synthetics.backends.backend_syngine module

Backend for making synthetic seismograms using Syngine.

class seismic.synthetics.backends.backend_syngine.SynthesizerSyngine(station_latlon, earth_model='iasp91')

Bases: seismic.synthetics.backends.synthesizer_base.Synthesizer

Class to synthesize seismograms using online Syngine service.

To write resultant stream to HDF5 format, add ‘ignore’ option:

synth_stream.write(‘test_synth.h5’, ‘h5’, ignore=(‘mseed’,))

synthesize(src_latlon, fs, time_window)

See documentation for synthesize()

seismic.synthetics.backends.backend_syngine.synthesizer()

seismic.synthetics.backends.backend_tws module

Backend for making synthetic seismograms using Telewavesim.

class seismic.synthetics.backends.backend_tws.SynthesizerMatrixPropagator(station_latlon, layerprops)

Bases: seismic.synthetics.backends.synthesizer_base.Synthesizer

Class to synthesize seismograms from a 1D model description using Kennett’s matrix propagator method.

seismic.synthetics.backends.backend_tws.synthesizer()

seismic.synthetics.backends.synthesizer_base module

Base class for seismogram synthesis class

class seismic.synthetics.backends.synthesizer_base.Synthesizer(station_latlon)

Bases: object

Base class for seismogram synthesizers.

compute_event_stats(src_lat, src_lon, eventid_base, src_depth_m=0, earth_model='iasp91', phase='P', origin_time=None)

Compute trace stats fields for a source single event.

Parameters

• src_lat – Source latitude

• src_lon – Source longitude

• eventid_base – Base string for event id

• src_depth_m – Source depth in metres

• earth_model – String name of earth model to use for ray tracing

• phase – Which phase is being modelled

• origin_time – Timestamp of the source event

Returns

stats dict

property station_latlon

abstract synthesize(src_latlon, fs, time_window)

Function signature for function to compute synthetic dataset of obspy streams.

Parameters

• src_latlon – Iterable of source (lat, lon) locations

• fs – Sampling rate in Hz

• time_window – Pair of time values relative to onset

Returns

obspy.Stream containing ZNE velocity seismogram
