The walls of St. Agata church, a centuries-old Roman Catholic cathedral located in Catalonia, did not escape the impact of the tremor, with photos showing pieces of bricks piling in front of the entrance. /VCG Photo

It was the biggest earthquake since the volcano rumbled to life on Monday. An ash cloud caused by the eruption also led to the temporary closure of the Sicilian airspace on Christmas Eve. /VCG Photo
