A powerful 6.6-magnitude earthquake rocked central Italy on Sunday, October 30th morning, injuring at least 20 people, in the strongest tremor to hit the country in more than three decades.

The earthquake follows tremors last week and comes on the heels of a devastating quake in August, which killed nearly 300 people and flattened entire villages.

Another awful aspect after the earthquake is a huge crack which appeared in a mountain near Ussita, cracking that did not exist until after the earthquake.
