Install SeisIO.jl to Mac M1

Currently we have a problem when adding the SeisIO.jl using Mac M1 chip. To avoid the error, try one of the options below:

• Option 1. Use the forked version of SeisIO. Type the follwing command in the Julia REPL:

using Pkg; Pkg.add(url="https://github.com/kura-okubo/SeisIO.jl");

• Option 2. Use the Docker container following SeisMonitoring_Example.

• Option 3. Follow (https://github.com/jpjones76/SeisIO.jl/pull/94/commits/9a8b4510636e442e89f3d0a76f63abc56f1ab054). We need to install the SeisIO.jl in develop directory:

]dev SeisIO 

Then, edit the ~/.julia/dev/SeisIO/Project.toml such that

HDF5 = "0.12.3, 0.13, 0.14.2"
LightXML = "0.8.1, 0.9"

You can avoid the precompile error for those packages. We corrected these dependencies in the forked version used in the option 1 above.

SeisBase.jl

We have developed this software package with SeisIO.jl v1.2.1, which is currently maintained as SeisBase.jl.

Installation

Type the commands below in the Julia REPL:

using Pkg; Pkg.update();
# Pkg.add(PackageSpec(name="SeisIO", version="1.2.1")); 
Pkg.add(url="https://github.com/kura-okubo/SeisIO.jl") # forked version used for the environment including Mac M1
Pkg.add(PackageSpec(name="SeisNoise", version="0.5.3"));
Pkg.develop(url="https://github.com/kura-okubo/SeisDvv.jl");
Pkg.develop(url="https://github.com/kura-okubo/SeisMonitoring.jl");

Tutorial

We created the notebook of the tutorial in the different github repository, SeisMonitoring_Example. You can find how to download the data, remove the transient signals, compute cross-correlations, stack the correlation functions and measure the dv/v.

See also the repoitory of SeisMonitoring_Paper for the post-processing using the dv/v over 20 years at Parkfield.
