Il terremoto verificatosi nella notte con epicentro nel reatino, di magnitudo 6, è stato forte quasi quanto quello, di magnitudo 6.2, che il 6 aprile 2009 distrusse L'Aquila.
Degli altri recenti grandi terremoti in Italia, quello del 1976 in Friuli è stato di magnitudo 6.2, quello dell'Irpinia (1980) di magnitudo 6.8, quello di Umbria e Marche (1997) di magnitudo 5.6, quello della pianura padana modenese (2012) di magnitudo 5.9.
"Sul nostro Pianeta, si verificano, in media, ogni anno, almeno un paio di terremoti distruttivi ed in Italia un sisma di magnitudo superiore a 6.3. ogni 15 anni in media. Ciò dovrebbe spingere a una maggiore cultura della prevenzione sismica e della protezione civile". Ha ricordato oggi Fabio Tortorici, presidente della Fondazione centro studi del consiglio nazionale dei geologi.
