A brief note in Flores Historiarum states that in 1113 CE, in the month of May, a great comet appeared, and a little afterwards there was an earthquake which threw down part of the city of Manistre (Mamistra), not far from Antioch, with two castles, called Triphalet and Mariacus.

The reference to a comet suggests that the event should be dated to 1114 CE. Kronk (1999 v.1:196) reports that this comet was widely recorded in monastic histories of the 12th–15th centuries, with dates ranging from 1113 to 1115, noting that the vast majority of reports place it in 1114 CE. He adds that although its late May visibility makes it somewhat similar to C/1110 K1, the consistent descriptions of a long tail contradict the observations of C/1110 K1 and increase the likelihood that there was a large comet seen in 1114.

Flores Historiarum mentions two comets—a large one in May 1113 CE and another in May 1114 CE. The latter is more likely the one associated with the earthquake, as it aligns more closely with the chronology given by other sources.
