EQcorrscan: EQcorrscan v0.0.9

A python package to conduct match-filter earthquake detections.

This package contains routines to enable the user to conduct match-filter earthquake detections using obspy bindings when reading and writing seismic data, and the correlation routine in openCV. Neither of these packages are installed by this software, due to a range of licenses being implemented. However, both are open-source and should be installed before using this package. This package was written to implement the Matlab routines used by Chamberlain et al. (2014) for the detection of low-frequency earthquakes.

This release works towards pep8 compatibility and fixes bugs from previous releases. Of note is a major bug-fix in match_filter - arguments were the wrong way round when calling the _template_loop internal function.

Again, update your version using:

pip install -U --no-deps EQcorrscan

For a full description of the changes from previous versions see the CHANGES.md file. The change-log for this version is as follows:

• Working towards following pep8
• Change how match_filter handles missing data - now remove template traces (which have been copied) rather than adding null traces to the data stream - more memory efficient, and faster
• Change float handling for large amplitudes in Sfile_utils
• Change distance decimal handling in Sfile_utils
• Add magnitude-frequency plotting to EQcorrscan_plotting
• Update tutorial and docs for tutorial
• Major bug-fix Change in match_filter - debug and index were the wrong way round from version 0.0.5 onwards, hence for multiple templates, cross-correlation vectors were not matched for templates. Will push a release because of this.
