1117 CE Quake

Between the 26th and 29th of June 1117 CE

by Jefferson Williams









Introduction & Summary

Contemporaneous source Fulcher of Chartres briefly described an earthquake sometime between the 26th and 29th of June in 1117 CE. Fulcher's account appears to have been largely repeated in Secunda pars historiae Iherosolimitane. However, Secunda pars added one additional detail - that there were building collapses (presumably in Jerusalem). Although Fulcher dated the earthquake to the 26th of June 1117 CE, earlier in the passage he described a total lunar eclipse and a full moon both of which he misdated 2-3 days too early. This suggests that his date for the earthquake was also 2-3 days too early. If we consider all possibilities, it appears that the earthquake struck sometime between the 26th and 29th of June.

Guidoboni and Comastri (2005) locate this earthquake in the vicinity of Scandelion Castle (12 km. from Tyre) due a report of repairs to the Castle immediately after Fulcher of Chartres described the earthquake. Ambraseys (2009) locates the seismic shaking in Jerusalem where Fulcher was living when he wrote the passage. It is not entirely clear whether Fulcher was an eyewitness to this earthquake.

Fulcher of Chartres Latin
Biography

Roman Catholic 1117 CE Jerusalem Fulcher of Chartres wrote that the earth trembled in Jerusalem in the night on the 26th of June in 1117 CE. However, earlier in the passage, he described a total lunar eclipse and a full moon both of which he misdated 2-3 days too early which suggests that his date for the earthquake was also misdated 2-3 days too early. Considering all possibilities, it appears that the earthquake struck some time between the 26th and 29th of June.

Guidoboni and Comastri (2005) locate this earthquake in the vicinity of Scandelion Castle (12 km. from Tyre) due a report of repairs to the Castle immediately after Fulcher of Chartres described the earthquake.

Secunda pars historiae Iherosolimitane Latin
Biography

Roman Catholic third quarter of the 12th c. Secunda pars historiae Iherosolimitane reports that a terrible earthquake was experienced in Jerusalem on 26 June 1117 CE where buildings were so shaken that they collapsed. The entire passage in Secunda pars is very similar to the passage by Fulcher of Chartres and appears to be sourced from it. Guidoboni and Comastri (2005) wrote that Secunda pars is traditionally considered to be a sort of epitome of the work of Fulcher of Chartres. Thus, if Fulcher of Chartres misdated the earthquake, Secunda pars probably misdated it too. Hence, as with Fulcher, the date of the earthquake described in Secunda pars is constrained between the dates of 26 and 29 June 1117 CE.

LX

The Great Plague of the Locusts

1. In the year 1117 of the Incarnation of Our Lord this queen who has been mentioned1 departed from the port of Acre on the day on which, in accordance with the rule of the church, the greater litany is chanted2 and with seven ships in her company crossed over to Sicily.

2. Then in the month of May an infinite multitude of locusts swarmed into the land of Jerusalem devouring more completely than usual the vines, field crops, and trees of all kinds.3 You could see them advance like an army of men in good order as if they had previously arranged it in council. When they had made their day's journey, some on foot and some flying, they mutually chose a resting place for themselves. And so when they had eaten up everything green, and had gnawed the bark of the trees, the wingless locusts as well as the others departed in companies.

3. Oh the wickedness of men who persist in their wicked perversity! How often and how much our Creator touches us with His reproaches and admonishes us, terrifies us by His portents, stirs us by His threats, instructs us by His lessons, and represses us by His punishment. But we always persist in our iniquities, despise His admonitions, and contemptuously violate His precepts.

4. What wonder that the Saracens or other wicked lords should take from us our lands since we ourselves reach out with thievish hands into the fields of our neighbors! Indeed we wrongfully cheat them with the furrow of the plow or otherwise secretly rob them with greedy acts of fraud and thus sinfully enrich ourselves from their possessions.

5. What wonder is it that, God permitting, the mice destroy our crops while they are sprouting from the roots in the ground or the locusts devour them ripened in the ear, or that they are damaged in the granaries by worms of every kind or by rotting, when we dishonestly sell the tithes owed to God or sacrilegiously retain them entirely?

LXI

The Portent of the Moon

1. In the following month, which was June, the moon appeared to us who were looking at it in the sky after cockcrow, first entirely red; very soon, however, the redness changed to black so that the moon lost the strength of its light for nearly two hours. This happened on the thirteenth of the month. If it had happened on the fourteenth we would certainly have thought it an eclipse.4

2. Therefore we regarded it as a portent. From this redness some conjectured that blood would be shed in battle; from the blackness others prophesied that a famine was coming. But we committed the matter to the disposition and providence of God, who foretold to His disciples that there would be portents in the sun and the moon [Luc. 21:25].

3. He moreover as He wills causes the earth to tremble and then to be still. This subsequently happened in the same month in the silence of an unseasonable night, on the sixth day before the Kalends of June.5

LXI I

The Castle Built near Tyre

1. Then the king built a castle near the city of Tyre, within five miles. He named it Scandalion, which interpreted means "Field of the Lion."6 He repaired the breaches in it and placed a garrison within to be a restraint upon the people of Tyre.

3 Cf. locust plague in May, 1114 (chap. lii, 4).

4 Fulcher, here using the Golden Number system of chronology, a lunar system for calculating the dates of Easter, expected the new moon on June 4, which he, however, regarded as the first of the month. He expected the full moon to occur fifteen days later on June 28 (or June 25 by his reckoning). However, his calculations were incorrect in this instance: the new moon came on June 2 (JW: verified with clearskytonight.com), and the full moon followed in fifteen days, on June 26 (JW: This appears to be a typographic error and should be 16 June - clearskytonight.com shows a Full Moon in Jerusalem on 16 June 1117 CE at 3:01 am) (which he regarded as June 13). Hence his astonishment and superstititious awe. He adds that if the full moon had appeared on the fourteenth day (i.e., at any other interval than fifteen days) he would have regarded it as an eclipse. For further discussion, see HF 604, note 3; and Henri Wallon, edition of Fulcher, RHC, Occ., III, 434, note b. Regarding the Golden Number system, see A. Giry, Manuel de diplomatique (Paris: Librairie Hachette et Cie, 1894), 148.

5 June 26, 1117.

6 Fulcher apparently errs in his interpretation of Scandalion, for William of Tyre explains that it was named after Alexander the Great, called "Scandar' in Arabic (XI, xxx).

English from Ambraseys (2009)

He moreover as He wills causes the earth to tremble and then to be still. This subsequently happened in the same month in the silence of an unseasonable night, on the sixth day before the Kalends of July. (Fulch. Gest. Franc. lxi/220).

English from Guidoboni and Comastri (2005)

1117. [...] The month of June. [...] When He wishes, God causes the earth to shake and then calms it again. That is what happened a little later that month, deep in the silence of the night, on the sixth day before the Calends of July [26 June]. Then the king [Baldwin of Jerusalem] built a fortified place about five miles outside the city of Tyre, and called it Scandelion, which means Field of the Lion, and he repaired the damage and posted guardians there to keep the said place under control

De signo lunae


[1] Sequenti quidem mense, qui lunius erat, apparuit nobis in caelum suspicientibus luna post galli cantum prius tota rubea; novissime vero, mutato rubore, nigredine adeo fuscata est, ut vim sui luminis per II paene horas perderet. contigit autem hoc die, qua eam XIII habebamus. quod si XIV die illo esset, eclipsim nimirum eius esse intelllgeremus.

nighttime between the 26th and 29th of June in 1117 CE This subsequently happened in the same month in the silence of an unseasonable night, on the sixth day before the Kalends of June
  • "before the Kalends of July" substituted for "before the Kalends of June" due to apparent typographic error (this error also shows up in the critical Latin edition by Hagenmeyer, 1913). An earlier paragraph (LXI paragraph 1) indicates that the events described occurred in June - not May.
  • Since Fulcher misdated the 16 June total lunar eclipse to June 13 and misdated the 16 June full moon to 14 June, he may have also misdated the earthquake - dating it 2-3 days too early. Although might be solveable by investigating the Golden Number system of chronology that Ryan (1969) says he employed, for now I am going to just say that the earthquake appears to have struck between the 26th and 29th of June.
  • NASA's Javascript Lunar Eclipse Explorer shows that a total Lunar Eclipse was visible in Jerusalem on 16 June 1117 CE starting at 12:05 am and ending at 5:44 am (local time). The total part of the eclipse lasted from 2:20 am until 3:28 am.
  • imcee dates this total lunar eclipse to 23 June 1117 CE however they are using the Gregorian Calendar for their date. Once this is converted to a Julian Date, they also have the eclipse occurring on 16 June 1117 CE (calculated using CHRONOS)
  • Fulcher of Chartres was an eyewitness to this eclipse and described it earlier in the text - before the earthquake. Fulcher reported the date of the eclipse as 13 June 1117 CE and stated that the moon lost the strength of its light for nearly two hours.

1117. [...] The plague of locusts was followed, on the sixth day before the Calends of July, by a terrible earthquake, which showed men the need to act rapidly in order to placate the wrath of God. Buildings were so shaken that they collapsed, and so the hard hearts of foolish men were moved to penitence.

English from Ambraseys (2009)

(1117) Following the plague of locusts, on 6 Kal. July, there was a most dreadful earthquake, which was a sign that the wrath of God would the quicker be placated. The buildings were shaken to ruins, that the hearts of callous men might be shaken to repent. (Bongars 574).

Latin from Guidoboni and Comastri (2005)

Anno M.C.XVII. [...]. Secutus est locustae pestem, sexto kalend. Julii, horribilis nimis terrae motus, iram Dei praemonens citius debere placari. Concutiebantur ad ruinam aedificia, ut dura hominum stolidorum ad poenitentiam concuterentur corda.

Latin from Recueil des Historiens des Croisades

Anno .M.C.XVII., hostium vice, Jerosolimitanum totum fere territorium infinitae multitudines occupavere locustarum, ita catervatim continuatimque de pessundatis jam locis ad alia procedentes pessundanda, ut ex devoratis cunctis virentibus terrae perpendere evidenter liceret Dominum praecepisse locustae indisciplinatorum devorare terras incolarum; si forte, revertentes ad cor, animadverterent perversi quam non locustis vastandi, sed ipsis Sarracenis tradi mererentur trucidandi.

And in the year five hundred and eleven of the ARABS (A.D. 1117) the Sultan GAYATH AD-DIN MAHAMMAD, the son of MALIK SHAH, died in ESFAHAN ; and there rose up after him his son Sultan MAhMOD. And in this same year also the Khalifah MUSTATHER died in BAGHDAD. And there rose up after him his younger son MUSTARSHID. And in this year also, which is the year fourteen hundred and twenty-nine [of the GREEKS, A.D. 1118], died ALEXIS, the king of the GREEKS, in the month of 'AB (AUGUST). He was a wise and strong man, and by his wisdom he saved CONSTANTINOPLE from the FRANKS. And his son 'IWANI (JOANNES) reigned after him. And his brother, and sister, and mother acted treacherously in respect of him. And having cast out his brother and sister into exile, and tonsured his mother and established her in a nunnery, the kingdom was established for him. And in this year the lord of EGYPT died, and the lord of GAZNAH also. And after a short time ROGER, the lord of ANTIOCH, was killed. Thirteen kings died within two years. Before they died a violent earthquake took place, and the death of the kings followed soon after it.

(a.H. 511 = 1117, a.H. 1429 = 1118) Thirteen kings died within two years. Before they died a violent earthquake took place, and the death of the kings followed soon after it.’ (These deaths included that of Emperor Alexis) (Abu’l-Faraj 281/ 248.)

All of the buildings were destroyed at the end of Phase IIb, probably by the strong earthquake that struck the region in 1033/4 [i.e., the 11th century CE Palestine Quakes]; both historical sources and the remains in other cities attest to this event. Following the earthquake, some of the buildings were left in ruins, but others were rebuilt. The buildings in Area A, for example, was never restored: the columns that had collapsed in the earthquake were discovered toppled on the floors of the courtyards belonging to the Phase IIb building.
Umm el-Qanatir possible ≥ 8 2nd Earthquake - undated - Wechsler et al (2008) report a collapse layer in a makeshift house that was built inside an abandoned synagogue that was likely seismically damaged from one of the Sabbatical Year Quakes (the Holy Desert Quake). The collapse layer from the makeshift house is not dated.

Jericho - Hisham's Palace possible ≥ 8
9-10
Later Earthquake - Alfonsi et al (2013) dated the causitive earthquake for the major seismic destruction at Hisham's Palace to the earthquake of 1033 CE unlike previous researchers who dated it to one of the Sabbatical Year earthquakes. Their discussion is reproduced below:
The archaeological data testify to an uninterrupted occupancy from eighth century until 1000 A.D. of the Hisham palace (Whitcomb, 1988). Therefore, if earthquakes occurred in this time period, the effects should not have implied a total destruction with consequent occupancy contraction or abandonment. Toppled walls and columns in the central court cover debris containing 750-850 A.D. old ceramic shards (Whitcomb, 1988). Recently unearthed collapses north of the court confirm a widespread destruction after the eighth century (Jericho Mafjar Project - The Oriental Institute at the University of Chicago). These elements support the action of a destructive shaking event at the site later than the 749 A.D. earthquake. The two well-constrained, major historical earthquakes recognized in the southern Jordan Valley are the 749 and 1033 A.D. (Table 1; Marco et al (2003); Guidoboni and Comastri, 2005). We assign an IX—X intensity degree to the here-recorded Hisham damage, whereas a VII degree has been attributed to the 749 A.D. earthquake at the site (Marco et al, 2003). Furthermore, Whitcomb (1988) defines an increment of occupation of the palace between 900 and 1000 A.D. followed by a successive occupation in the 1200-1400 A.D. time span. On the basis of the above, and because no pottery remains are instead associated with the 1000-1200 A.D. period at Hisham palace (Whitcomb, 1988), we suggest a temporary, significant contraction or abandonment of the site as consequence of a severe destruction in the eleventh century.
Mishmar David possible ≥ 6 or ≥ 7 End of Stratum V Earthquake - 11th century CE - Yannai (2014) noted that an immense building in Stratum V of Area B was damaged, possibly in another earthquake, either that of 1033 or of 1068 CE. Yannai (2014) noted that Stratum V buildings [in Sub-Area C1] were destroyed by a second earthquake, either the one that struck in 1033 or that of 1068 CE.
Ramat Rahel possible ≥ 8 10th-11th century CE collapse - In The Tel Aviv - Heidelberg Joint Project - The 2006 and 2007 seasons at Ramat Rahel mention is made of a 10th-11th century collapse in Area D1
A massive stone collapse had covered the floors of the different architectural units. The many broken pottery vessels date the collapse of the building to the Abbasid period or to the beginning of the Fatimid period (10th–11th century CE)
Beit-Ras/Capitolias possible Later Earthquakes - Al-Tawalbeh et. al. (2020:14) discussed archaeoseismic evidence for later post abandonment earthquakes
We believe that filling up the cavea and orchestra of the theater happened parallel with the construction of the enclosing wall that essentially put all of the remaining building underground. Underground facilities are significantly less vulnerable to seismic excitation than that above-ground buildings (Hashash et aL, 2001). Understandably, when each wall and arch are supported by embedding sediment (dump in Beit-Ras), the observed deformations of the excavated theater mostly cannot develop unless unsupported. Therefore, evidence of damage due to any subsequent events, such as A.D. 551, 634, 659, and 749, cannot be observed, because the possibility of collapse of buried structures is not plausible. However, potential collapse of other above-ground structures within the site of Beit-Ras cannot be ignored, such as the upper elements of the theater's structures, which were still exposed after the filling of the theater with debris. Several observations indicated that many collapsed elements of the upper parts of the theater were mixed with the debris, as documented in excavation reports by Al-Shami (2003, 2004). Another example suggesting the effect of the later events, such as that of A.D. 749. Mlynarczyk (2017) attributed the collapse of some sections of the city wall of Beit-Ras to this event, based on the concentration of collapsed ashlars and the age of collected pottery from two trenches excavated to the west of the theater structure.
Al-Tawalbeh et. al. (2020:6) also noted the following about the eastern orchestra gate:
The basalt masonry in the upper left suggests a later local collapse and repair phase, where the basalt courses are overlaying the marly-chalky limestone to the left of the walled arched eastern gate.
Petra - Introduction n/a n/a n/a
Petra - Jabal Harun possible ≥ 8 Phase 12 destruction event - not well dated - Mikkola et al (2008) noted that in this destruction event all remaining roof structures collapsed and there was a layer of stone tumble. Hard-packed, clayey soil directly under the lowermost deposits of stone tumble [...] contained relatively few finds apparently making it difficult to date. Also found in the stone tumble were the remains of two fallen arches, a row of voussoirs, some drums fallen from a column, and many other architectural elements found throughout the complex.
Petra - Petra Church possible ≥ 8 Fiema et al (2001) characterized structural destruction of the church in Phase X as likely caused by an earthquake with a date that is not easy to determine. A very general terminus post quem of the early 7th century CE was provided. Destruction due to a second earthquake was identified in Phase XIIA which was dated from late Umayyad to early Ottoman. Taken together this suggests that the first earthquake struck in the 7th or 8th century CE and the second struck between the 8th and 16th or 17th century CE.
Petra - Blue Chapel and the Ridge Church possible Later undated earthquake(s)- Perry in Bikai et al (2020:70) noted that from the 8th c. A.D. on, the abandoned structures suffered extensive damage from repeated earthquakes.

Tell Saidiyeh and Ghor Kabed Trenches

Ferry et al (2011) detected 12 surface rupturing seismic events in 4 trenches (T1-T4) in Tell Saidiyeh and Ghor Kabed; 10 of which were prehistoric. The tightest chronology came from the Ghor Kabed trenches (T1 and T2) where Events Y and Z were constrained to between 560 and 1800 CE.

Note: Although Ferry et al (2011) combined archaeoseismic interpretations, their paleoseismic evidence, and entries from earthquake catalogs to produce earthquake dates and some overly optimistic probabilities, only the paleoseismic data is presented here. Ferry et al (2011)'s archaeoseismic data was researched and is treated separately.

Notes

Ambraseys (2009)

AD 1117 Jun 26 Jerusalem

An earthquake occurred, probably in the region of Jerusalem. It may have caused structural damage.

The principal source for this event is Fulcher, who places it in 1117 on the sixth day before the Kalends of July (26 June; Fink actually gives ‘on the sixth day before the Kalends of June’, which is probably an accidental error), shortly after an eclipse. Fulcher regards the earthquake as something of a portent, especially insofar as the eclipse which preceded it did not occur on the expected date (Fulch. Gest. Franc. LXI/219 and n. 1).

The Historia Hierosolymitana of about 1122 also records an earthquake on the same date, following a plague of locusts; it notes that ‘the Buildings were shaken to ruins’.

Abu’l-Faraj (writing in the thirteenth century) notes the deaths of ‘thirteen kings’ during (5 May 1117 to 23 April 1118) a.H. 511 and a.S. 1429 (September 1117 to September 1118), including that of the Byzantine emperor Alexius I Comnenus (died 15 August 1118, Grumel 1958, 358). Before these deaths, he says, an earthquake occurred. Of course, it is not certain that Abu’lFaraj is referring to the same event as Fulcher; he could be alluding to the Constantinople earthquake of 1118, although Fulcher’s earthquake occurred closer to Abu’lFaraj’s main area of interest, which was Syria. See also Alexandre (1990, 147–154).

Guidoboni and Comastri (2005, 129–130), on the basis of a garbled Armenian colophon, split this earthquake into one earthquake in Jerusalem and another in the district of Vaspurakan in Armenia.

Notes

He moreover as He wills causes the earth to tremble and then to be still. This subsequently happened in the same month in the silence of an unseasonable night, on the sixth day before the Kalends of July. (Fulch. Gest. Franc. lxi/220).


(1117) Following the plague of locusts, on 6 Kal. July, there was a most dreadful earthquake, which was a sign that the wrath of God would the quicker be placated. The buildings were shaken to ruins, that the hearts of callous men might be shaken to repent. (Bongars 574).


(a.H. 511 = 1117, a.H. 1429 = 1118) Thirteen kings died within two years. Before they died a violent earthquake took place, and the death of the kings followed soon after it.’ (These deaths included that of Emperor Alexis) (Abu’l-Faraj 281/ 248.)

(057) 1117 June 26 Scandelion [Lebanon]

On 26 June 1117, an earthquake caused collapses at the fortress of Scandelion (south of Tyre), and in an area which the sources do not identify but must have been in Palestine (the principal source, Fulk of Chartres, was living in Jerusalem at the time of the earthquake) and southern Lebanon (Scandelion is in fact on the southern coast of Lebanon, about 12 km from Tyre).

After recording a plague of locusts and a lunar eclipse, Fulk of Chartres writes:
1117. [...] The month of June. [...] When He wishes, God causes the earth to shake and then calms it again. That is what happened a little later that month, deep in the silence of the night, on the sixth day before the Calends of July [26 June]. Then the king [Baldwin of Jerusalem] built a fortified place about five miles outside the city of Tyre, and called it Scandelion, which means Field of the Lion, and he repaired the damage and posted guardians there to keep the said place under control
1117. 1...] Quidem mense, qui Iunius erat Deus 1...] qui etiam quando vult terrain facit tremere, et postea quiescere; quod subsequenter accidit in eodem mense noctis intempestae silentio, VU kalendas Iulii.

Tune edificavit rex quoddam castrum prope urbem Tyrum, intra quintum ab urbe milliarium, quod vocavit Scandalion, et Campum Leonis interpretatum, et resarcivit diruta eius, et posuit in eo custodes ad coercendum urbem predictam.
Lisiard of Tours, who depends largely on Fulk of Chartres, records:
1117. [...] The plague of locusts was followed, on the sixth day before the Calends of July, by a terrible earthquake, which showed men the need to act rapidly in order to placate the wrath of God. Buildings were so shaken that they collapsed, and so the hard hearts of foolish men were moved to penitence.
Anno M.C.XVII. [...]. Secutus est locustae pestem, sexto kalend. Julii, horribilis nimis terrae motus, iram Dei praemonens citius debere placari. Concutiebantur ad ruinam aedificia, ut dura hominum stolidorum ad poenitentiam concuterentur corda.
Tolomeo da Lucca, a Tuscan author who lived from about 1240 to 1327, mistakenly associates this earthquake with the one which occured in the same year in Italy, as well as with the death of Alexius I Comnenus immediately afterwards.
