p-wave-detection (0.2.1)
Installation
pip install --index-url About this package
Automatic detector of the first arrival time of the P wave
P Wave Detection Tool
This is a tool to automatically measure the arrival time of P wave within a time window of 4 seconds.
Requirements
To install this model a recent installation of Miniconda is required.
Installation
To install this model please run:
git clone https://git.plgrid.pl/scm/eai/p-phase-picker.git
cd p-phase-picker
conda env create -f environment.yml
conda activate ross-2018
Running
To measure the arrival time please run:
p_wave_detection [-m MODEL] SEISMOGRAM DATE
e.g.:
p_wave_detection PL.BRDW..EHZ.D.2016.068 "2016/03/08 00:19:57.515"
Important Notes
Any seismogram readable by ObsPy can be provided. The minimal sample is 400 points, and the sampling rate must be 100 Hz.
The DATE selects a centre of a 4 seconds window within the seismogram. The DATE should be formatted according to the ISO8601:2004 for examples see the ObsPy documentation, especially the 2nd point in the Examples section.
The model returns a arrival time with a respect to the given DATE. An exemplary output is:
Prediction: -0.024044 s
which means that the predicted P wave arrival time is 0.024044 seconds before the given DATE.
Credits
The model is based on work by Ross, Meier and Hauksson (2018)
