On 28 March 193, Pertinax was at his palace when a contingent of some three hundred soldiers of the Praetorian Guard rushed the gates (two hundred according to Cassius Dio). Sources suggest that they had received only half their promised pay. Neither the guards on duty nor the palace officials chose to resist them. Pertinax sent Laetus to meet them, but he chose to side with the insurgents instead and deserted the emperor.

Because Julianus bought his position rather than acquiring it conventionally through succession or conquest, he was a deeply unpopular emperor. When Julianus appeared in public, he frequently was greeted with groans and shouts of "robber and parricide." Once, a mob even obstructed his progress to the Capitol by pelting him with large stones.

The final event of the sequence was of similar magnitude to the first and had an epicenter about 20 km east of the fourth, near Girifalco and Borgia in the Catanzaro Basin. The earthquake lasted for about ten seconds, and many villages were destroyed with many hundreds dead in Borgia, Girifalco, Maida, and Cortale. Landslides were common and sand volcanoes were seen, particularly on the banks of the Amato river. This earthquake has not been tied to a particular fault, but a recent re-evaluation of the intensity data indicates that the isoseismal areas are elongated NE–SW, suggesting faulting of similar trend to that observed for the other earthquakes in the sequence.

On March 28, 1849, the draft of the Paulskirchenverfassung constitution was finally passed. The new Germany was to be a constitutional monarchy, and the office of head of state ("Emperor of the Germans") was to be hereditary and held by the respective King of Prussia.
