Location Workflow (LOC-FLOW) CookBook
Miao Zhang ([email protected])
Ruijia Wang ([email protected])
August 2021
Version 1.0
LOC-FLOW is a “hands-free” earthquake location workflow to process continuous seismic
records: from raw waveforms to well located earthquakes with magnitude calculations. The
package assembles several popular routines for sequential earthquake location refinements,
suitable for catalog building ranging from local to regional scales (see Liu et al., 2020 for
broadband station application and Wang et al., 2020 for a nodal array application).
The LOC-FLOW is released and maintained at https://github.com/Dal-mzhang/LOC-FLOW.
Please download and install the packages first (PhaseNet[contains Obspy], REAL, VELEST,
HYPOINVERSE, hypoDD, GrowClust, FDTCC, Match&Locate; see [STEP 0]). Questions related to the
original packages should be addressed to the corresponding authors. All other credits to Miao
Zhang (also author of REAL and Match&Locate), Min Liu (also author of FDTCC), and Tian
Feng, who integrated these packages and made the I/O codes publicly available. If you find any
part of the workflow useful, please cite the corresponding publications of the packages and/or
our work.
Figure1. Overview of the LOC-FLOW and packages involved.
Disclaimer:
While under continuous effort of improvements, the workflow has been tested by multiple
research groups, but is made available without warranty. Users are free to make
modifications to the programs to meet their particular needs, but are discouraged from
distributing modified code to others without notification of the authors. Feedbacks, potential
improvements and bug fixes should be addressed to the corresponding authors of these
packages.
Any commercial use of any part of the codes, original packages, modified packages,or
figures/text of this document is prohibited. The authors of this document and/or corresponding
software packages reserve all rights.
The views, thoughts, and opinions expressed in the text belong solely to the author(s), and
not necessarily to the authors’ employer, organization, committee or other group or individual.
Color and Text Style Definition:
codes to run (italic & bold) in corresponding colors in Figure 1
To run codes:
python CODENAME.py
perl CODENAME.pl
bash CODENAME.sh
CODENAME.m in MATLAB
set up files for codes (may need to open and edit)
inputs/outputs (names may contain wildcards like *, [YYYYMMDD], STATION)
Tips and suggestions will be in blue boxes like this.
Installation
[STEP 0] time: usually tens of minutes
● Download and install software packages
software_download.py download and manually install PhaseNet, REAL, FDTCC, hypoDD,
GrowClust and Match&Locate (optional). A modified VELEST is included in the
current version of REAL. PhaseNet installation environment includes ObsPy,
which provides functions for data downloading and processing, as well as the
STA/LTA picking.
Download and install HYPOINVERSE separately:
https://www.usgs.gov/software/hypoinverse-earthquake-location
run_install.sh move all commands to “bin” directory, manually add the “bin” path into your
environment (~/.bash_profile or ~/.bashrc)
● Download data
waveform_download_mseed.py requests continuous data from FDSN providers. Store both
raw mseed and response free SAC files. SAC files will be used for local
magnitude estimation (see 6.Optional Utilities) and dt.cc calculation by FDTCC.
waveform_download.py alternative python script to download response free SAC data (need
to provide station list: station_all.dat)
● Convert data and select station
phasenet_input.py prepares data inputs for PhaseNet to run, and station list (station.dat) for
next steps
[STEP 1a or 1b] could be time consuming.
Suggest starting with [STEP 2] by assuming we have the data and picks .
Keep in mind that [STEP 5] and later still need the continuous SAC data.
The whole workflow was tested on MacBook Pro (2.9 Ghz, 6-core intel core i9, 32G
memory), including the estimated running time.
