From: Monitoring soil radon during the 2016–2017 central Italy sequence in light of seismicity
Geographical setting of the Amatrice-Visso-Norcia seismic sequence. Green triangles indicate the location of the radon monitoring stations CTTR and NRCA. The earthquakes with M ≥ 1.5 recorded by the INSN from July 2016 to February 2017 (about 37,000 events) are shown as grey circles. Yellow stars indicate the epicentres (along with corresponding focal mechanisms) of the 4 largest mainshocks of the sequence, labeled according to the inset table on the bottom left corner. The Generic Mapping Tools30, Version 5.2.1, (https://gmt.soest.hawaii.edu/) were used to generate the map.
