matlab package able to forecast strong aftershocks starting from the first hours after the mainshocks

software description

nestore is a matlab package capable to estimate, during ongoing of an aftershock sequence following a damaging earthquake, the likelihood of the occurrence of another strong earthquake.

the code is based on the seismicity characteristics and uses a machine learning approach to provide forecasting for the ongoing seismic sequence.

starting from an input catalogue, the package

1. provides an identification of clusters by a window based method (cluster identification module)
2. trains the algorithm by machine learning on cluster's features (training module)
3. tests the algorithm performances (testing module)
4. classifies in near-real-time new clusters (near-real-time classification module)

installation

download nestorev1.0.zip and extract in a folder you prefer (e.g. nestore_folder)or clone nestore repository on your computer; no other action is required. nestore has been tested on matlab r2018a and later versions.

usage

to run nestore code start matlab, move in your sub-directory nestorev1.0/user(e.g. nestore_folder/nestorev1.0/user); in the matlab command line, type the corresponding run you need (e.g. run_training); examples are provided. see folder_struc.txt and fileinput_format.txt for further details.

software support

this package is the first online version of nestore, so any suggestions or bug reporting are welcome. please contact
