Abstract

The software package PyMPA is an open source seismological software. It consists of some separate utilities for data preparation, the main program, and post-processing tools to obtain a catalog and verify events. PyMPA is designed to detect microseismicity from the cross-correlation of continuous data and templates.

Motivation and significance

The software was developed in the framework of a 2013-2015 bilateral project between Italy and Japan "Detection of slow slip events and space-time cluster analysis of low magnitude tremors preceding the 2009 L'Aquila earthquake and the 2012 Emilia seismic sequence in Italy", and was co-funded by Ministero Affari Esteri (Italy) - Scientific and Technological Collaboration Executive Program. Further improvements to the code are planned within Project H2020 - SERA 2017-2019 http://www.sera-eu.org/.

System requirements

Python installed to run the program (version 2.6 or more) is required [http://python.org] Python 3 with Obspy installed (since version 0.10.1) is supported. Installing Obspy implies Numpy, Scipy, Pandas and Matplotlib libraries. For details on installing Obspy, please, consult the [official guide] (https://github.com/obspy/obspy/wiki).
