For those in Italy

Collect

O almighty and everlasting God, who lookest down upon the earth and makest it tremble, spare those who are afraid, and show Thy mercy those who implore Thee; that we who fear Thine anger, which shaketh the foundations of the earth, may evermore enjoy Thy mercy, which healeth its commotions. Through our Lord Jesus Christ, Thy Son, Who liveth and reigneth with Thee in the unity of the Holy Ghost, God, world without end. Amen.

Secret

O God, who didst establish the earth on firm foundations, receive the offerings and prayers of Thy people, and by wholly removing the perils of earthquake, turn the terrors of Thy divine anger into healing remedies for mankind: that those who are of the earth and to the earth shall return, may rejoice in becoming citizens of heaven by the holiness of their lives. Through our Lord Jesus Christ, Thy Son, Who liveth and reigneth with Thee in the unity of the Holy Ghost, God, world without end. Amen.

Postcommunion

We beseech Thee, O Lord, to keep us, who receive Thy holy mysteries, and by Thy heavenly power make firm the earth, which we see trembling because of our sins; that men may know in their hearts that these scourges come from Thy wrath and cease by Thy mercy. Through our Lord Jesus Christ, Thy Son, Who liveth and reigneth with Thee in the unity of the Holy Ghost, God, world without end. Amen.
