The 1687 earthquake marked a turning point in the history of Lima as it coincided with a recession in trade, a reduction of silver production and economic competition by other cities such as Buenos Aires. To add to these problems, on October 28, 1746, a powerful earthquake severely damaged the city and destroyed Callao, forcing a massive rebuilding effort under Viceroy José Antonio Manso de Velasco. This disaster led to an intense devotion for an image of Christ called The Lord of the Miracles, which has been taken out in procession every October since 1746.
