A Practical Seismological Database Library in Python.

Project description


Pisces is a Python library that connects your geophysical analysis environment to a SQL database that uses the Center for Seismic Studies (CSS) 3.0 or NNSA KB Core table schema.



Build Status


  • Import/export waveforms directly to/from your database.
  • Build database queries using Python objects and methods (SQLAlchemy), not by concatenating SQL strings.
  • Integration with ObsPy.
  • Geographic filtering of results.



  • ObsPy
  • Click
  • C compiler (for optional e1 dependency)

Install from PyPI:

pip install pisces

If you use "e1" format data, you also need to install the e1 package:

pip install e1

You can install them both at the same time with:

pip install pisces[e1]

Install current master from GitHub:

pip install git+
