# This is a notification that recent earthquake(s) may have induced noticeable displacements of one or more IGS stations.
#
# This message and the table below were generated automatically based on the following procedure:
# * The Global Centroid-Moment-Tensor (CMT) catalog (https://www.globalcmt.org/) is scanned every day for new earthquakes.
# * For every new earthquake, the width, length and slip of the rupture are estimated from:
# - Yen & Ma (2012; https://doi.org/10.1785/0120100046)'s scaling law if the earthquake magnitude is less than 7.6;
# - Mai & Beroza (2000; https://doi.org/10.1785/0119990126)'s scaling law it the earthquake magnitude is larger.
# (See justification for these choices in Métivier et al., 2014; https://doi.org/10.1002/2014JB011280.)
# * For every new earthquake, based on its estimated CMT and rupture parameters, co-seismic displacements are calculated
# at all IGS stations using Okada (1985; https://doi.org/10.1785/BSSA0750041135)'s approach. Given that the CMT inversion
# from seismic waves gives rise to two possible solutions for the rupture plane, two possible co-seismic displacements
# are calculated for every station and earthquake.
# * If any calculated 3D co-seismic displacement of an IGS station exceeds 1 mm, it is included in the table below.
#
# Warning : The co-seismic displacements thus calculated rely on several coarse approximations. They should not be used as
# estimates of the actual co-seismic displacements, but only as rough orders of magnitude.
#
# The column "RF?" in the table below indicates whether each station is part of the current IGS reference frame (IGb20),
# hence might need to stop being used as a reference frame station after the earthquake.
#
# The successive co-seismic displacements thus calculated are compiled in a cumulative table available at:
# ftp://igs-rf.ign.fr/pub/coseismic/IGS_coseismic.dat
