No need to fret, the Leaning Tower isn’t leaning more than beforeDespite the obvious temptation, there is no evidence that the Leaning Tower of Pisa is leaning any further. Later on, a more noticeable magnitude-3.2 tremor struck at 1.04pm, with its epicentre around five kilometres from Pisa and at a depth of 11 kilometres. The Tuscany regional government convened its crisis unit, bringing together civil protection teams, prefectures, councils, emergency services and infrastructure operators. The strongest known historical earthquake in this part of Tuscany struck around Orciano Pisano in August 1846 and has been estimated at magnitude 6.0.
