python-seispy 1.2.18

No project description provided

Seispy is a Python module for processing seismological data and calculating Receiver Functions. The advanced functions are available to improve the Obspy.

Dependencies

• Python >= 3.6
• ObsPy >= 1.1.0
• NumPy >= 1.16
• SciPy >= 1.2.0
• matplotlib >= 3.0.0
• pyqt5 >= 5.12.0
• scikits.bootstrap >= 1.0.0

Installation

See Seispy documentation in detail.

Libraries

• seispy.distaz: Calculate distance and azimuth credited by the lithospheric seismology program at USC, but numpy.ndarray operations are supported.
• seispy.geo: Tiny codes of geophysics.
• seispy.decon: Functions of deconvolution transferred from iwbailey/processRFmatlab including
  • Iterative time domain deconvolution method (Ligorría and Ammon 1999 BSSA).
  • Water level frequency domain deconvolution method (CJ. Ammon 1991 BSSA)
• seispy.rf: Procedure for RF calculation. The functions of match_eq, search_eq invoked obspy.core.UTCDateTime and obspy.clients from the Obspy.
• seispy.eq: RF processing for each event, which invoked obspy.io.sac, obspy.signal, obspy.taup and obspy.core.Stream from the Obspy.
• seispy.hk: H-k stacking for single station (Zhu and Kanamori 2000 JGR).
• seispy.rfani: A joint method for crustal anisotropic calculation (Liu and Niu 2011 GJI).
• seispy.slantstack: Slant stacking for single station (Tauzin et al., 2008)
• seispy.rfcorrect: Subsequent process of RFs including moveout correction and time to depth conversion (1D and 3D) (see Xu et al., 2018 EPSL)
• seispy.ccpprofile: CCP stacking along a profile.
• seispy.ccp3d: 3-D CCP stacking with extracting depth D410 and D660.

Commands

Receiver Functions

• prf: Calculate PRFs for a station.
• pickrf: Pick PRFs with virtual quality control after the calculation.
• plotrt: Plot PRFs with R and T components order by back-azimuth.
• plotr: Plot PRFs with R component order by back-azimuth.
• hk: H-Kappa stacking for estimating Moho depth and crustal Vp/Vs.
• rf2depth: Convert PRFs to depth axis.
• ccp_profile: Stack PRFs along a profile with a CCP stacking method.
• ccp3d: Stack PRFs with spaced bins.
• rfani: Estimating crustal anisotropy with a joint method.
• rfharmo: Harmonic decomposition to extract constant component of RF and plot dip/anisotropic components.

Others

• veltxt2mod: Create 3D velocity model with numpy.lib.npyio.NpzFile format from a ASCII table file.
• ndk2dat: Convert the GCMT catalog file ("ndk" format) to the list file for the prf command.
• updatecatalog: Automatically update the GCMT catalog.
• setpar: Set up the values in configure files.

TODO

• Download seismic data from web service for RF calculation.
