SCDetect - A SeisComP Module for cross-correlation based earthquake detection

About

SCDetect is a SeisComP package. With the extension module scdetect-cc it implements both real-time and classical offline earthquake detection based on waveform cross-correlation, also called matched filtering or template matching. Again, the underlying cross-correlation algorithm is based on computing the Pearson Correlation Coefficient .

The module allows both single-stream and multi-stream earthquake detection.

In case the detection parameters exceed the configured thresholds, scdetect-cc declares a new origin.

Besides, magnitudes may be estimated based on multiple magnitude estimation methods (regression, amplitude ratios).

git clone --branch $TAG https://github.com/SeisComP/common.git seiscomp/src/base/common
git clone --branch $TAG https://github.com/SeisComP/main.git seiscomp/src/base/main

# [... etc ...]

Next, clone SCDetect:

git clone https://github.com/swiss-seismological-service/scdetect.git seiscomp/src/extras/scdetect

Dependencies

Besides of the SeisComP core dependencies the following packages must be installed to compile SCDetect:

• libsqlite3-dev (Debian, Ubuntu), sqlite-devel (RedHat, Fedora, CentOS), dev-db/sqlite (Gentoo)

E.g. on Ubuntu simply invoke:

sudo apt-get install libsqlite3-dev

Compile and Install

For compiling and installing SeisComP (including SCDetect), please refer to https://github.com/SeisComP/seiscomp#build.

Tests

NOTE: executing SCDetect related tests requires SeisComP to be installed, beforehand.

In order to run all SeisComP tests (including those of scdetect-cc and possibly additionally installed third party modules), either execute

make test

in the build directory, or use the ctest executable from cmake (also within the build directory). E.g. in order to run only SCDetect related tests, invoke

ctest -R "^test_scdetect.*"

For additional information, please also refer to SeisComP's unit testing guide .
