After the strong tremors of 26 October (of magnitude ML 5.4 at 19.10 and of magnitude 5.9 at 21.18) who activated the area on the border between Marche and Umbria north of the area activated on 24 August, the National Seismic Network of the National Institute of Geophysics and Volcanology (INGV) has located over 900 events: are more than 80 those including magnitude between 3 and 4, 5 localized earthquakes di magnitude between 4 and 5.
Map of the northern part of the seismic sequence from 24 August to 28 October 2016 (10.00 am). The white star is the magnitude 5.4 event on August 24. The two red stars are the earthquakes that occurred on 26 October with a magnitude of ML 5.4 at 19.10 (southern star) and a magnitude 5.9 at 21.18 (the northernmost star).
These are the details of the strongest earthquakes:
