Signal processing for field and experimental data for earthquake engineering

Project description

Testing Status PyPi version License ECP project


A Python package for seismic signal processing.

How to Use

[Eqsig documentation](


Generate response spectra

import numpy as np
import matplotlib.pyplot as plt
import eqsig.single

bf, sub_fig = plt.subplots()
a = np.loadtxt("<path-to-acceleration-time-series>")
dt = 0.005  # time step of acceleration time series
periods = np.linspace(0.2, 5, 100)  # compute the response for 100 periods between T=0.2s and 5.0s
record = eqsig.AccSignal(a * 9.8, dt)
times = record.response_times

sub_fig.plot(times, record.s_a, label="eqsig")

Useful material


How do I get set up?

  1. Run pip install -r requirements.txt


Tests are run with pytest

  • Locally run: pytest on the command line.
  • Tests are run on every push using travis, see the .travis.yml file


To deploy the package to you need to:

  1. Push to the pypi branch. This executes the tests on
  2. Create a git tag and push to github, run: or manually:
git tag 0.5.2 -m "version 0.5.2"
git push --tags origin pypi


Built via Sphinx following:

For development mode

  1. cd to docs
  2. Run make html

Docstrings follow numpy convention (in progress):

To fix long_description in pip install collective.checkdocs, python checkdocs
