The space union of all circles (grey and yellow) is the area analysed by the
M8S algorithm. Yellow indicate the area of increased probability of
M6.5+ earthquakes. The Friuli earthquake has the following parameters:
Date 1976.05.06, latitude 46.23°N, longitude 13.13°E, depth 12 km,
M_{max}=6.5. The Irpinia earthquake has the following parameters:
Date 1980.11.23, latitude 40.85°N, longitude 15.28°E, depth 18 km,
M_{max}=6.7. Both of them are inside the area of alarm.
