Secunda Pars is a text traditionally considered to be a sort of epitome of the work of Fulcher of Chartres ( Guidoboni and Comastri, 2005). Earthquakes are described in 1113, 1114, and 1115 CE, though the chronology appears somewhat muddled.

• 1113 CE — In what appears to be July–August 1113 CE, two shocks are described: the earth is shaken twice. A terrible earthquake, and the overthrow of the buildings, withering away, threatens mortals with fear. Immediately before this, Secunda Pars notes that the sea is disturbed even more than usual, and even denies the possibility of fishing in the seas, possibly describing a minor tsunami or seiche. The location is unspecified, but the two shocks occur during hostilities in Galilee between Baldwin I’s Crusader army and Maudud’s Seljukid forces. Ambraseys (2009) characterizes this account as questionable.


• 1114 CE — Secunda Pars states that in April–May and the following [months?] of 1114 CE a horrible earthquake struck and that some parts of the city of Mamistria were overturned and many towns were affected in the region of Antioch, some partially destroyed and some fully destroyed, with some of the people killed. It adds that also in the city of Mariscum, the entire populace was overwhelmed by the sudden collapse of the buildings and in the Euphrates, a town called Thihalet was completely overthrown. Luard (1890 v.2:43 n.7) identifies Mariscum as Marash. The location of Thihalet is debated: Ryan (1969:210 n.5) suggests Balis on the Euphrates, while Ambraseys (2009) identifies Trialeth as Tell Khalid (Trialeth), a fortified site at the head of the Sajur River, a tributary of the Euphrates. Guidoboni and Comastri (2005) instead propose that Trihaleth corresponds to modern Akçakoyunlu.
  
  These authors argue that the compiler of Secunda Pars misread Fulcher of Chartres and thus misdated the event. They note that the April–May 1114 earthquake follows a locust swarm described by Fulcher which actually preceded his earthquake account. Fulcher dated:
  
  
  • an earthquake at an unspecified location to 10 August 1114 CE, following the April–May locust invasion;
  • the destruction of Mamistra to 13 November 1114 CE;
  • a greater earthquake which destroyed Marash and Trialeth to sometime in 1114 CE;
  • an earthquake that demolished Mamistra and other places in the area of Antioch to sometime in 1115 CE.
  
  Ambraseys (2009) and Guidoboni and Comastri (2005) interpret the Latin text to indicate that Jerusalem was shaken during the 1114 CE event described in Secunda Pars. However, as read from the RHC edition, the passage seems instead to refer to Mamistra:
  
  prius locustarum multitudine infinita ex Arabiae partibus convolante, a territorium Jerosolimitanum per dies aliquot vehementer vastalum est; mense Aprili vel Maio et sequenti terrae motu horribiliter concussum Mamistriae urbis pars nonnulla subversa.
  
  This text lacks a semicolon between concussum and Mamistriae. Perhaps other editions, such as that of Bongars (1611:610–611), insert a semicolon, suggesting a separate earthquake in the territory of the Jerusalemites.


• 1115 CE — Secunda Pars reports that in this year an earthquake overthrew the city of Mamistra and that most other places in the Antiochene territory suffered a similar horror. The date is given simply as 1115 CE.
