Quake felt in Florence and across Tuscany.

In an incredible coincidence, the testing of a new earthquake alert message in Italy's Tuscany region on Wednesday was followed minutes later by a real earthquake.

Tuscan residents received the test emergency IT-Alert message on their cellphones at midday, only for the central Italian region to be shaken by a 3.7-magnitude earthquake at 12.19.
