A Python package for seismic signal processing.

How to Use


Generate response spectra

.. code-block:: python

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:

.. code:: bash
git tag 0.5.2 -m "version 0.5.2"
git push --tags origin pypi


Built via Sphinx following:
