ELECTRONIC SUPPLEMENTARY MATERIAL ESM 1 Preliminary List of Historic Earthquakes that Caused Damage in Jerusalem The following table integrates reports of historic earthquakes that caused damage in Jerusalem. It is based on critical reviews and investigations that rely on contemporary sources. Relevant comments from other sources are added. In light of the difficulties discussed by Ambraseys (2005), this should be regarded as a preliminary list and further detailed examination is required to establish the full scope of seismic damage to Jerusalem. Date of the earthquake: as detailed as known (UT): year, month, day, hour, minute. Location in DST, not necessarily on the main transform: N- north of Israel; C- in Israel, north of the Dead Sea; S- in Israel, south of the Dead Sea. Estimated size: following the broad categories suggested by Ambraseys and Jackson (1998): L- large (7.8 > Ms ≥ 7.0), M- Moderate (7.0 > Ms ≥ 6.0) and S- small (Ms < 6.0). Date of Earthquake 363 05 18-19, night 634 09 Location in DST C C Est. Size Source of data, reported damage and comments M-L This seems to be a significant earthquake that caused widespread damage. Guidoboni et al. (1994): Contemporary sources report of damage to the temple area which was under construction and a fire that followed it. Later sources, however, of the 6th century that translated what may have been written by the bishop of Jerusalem at the time of the earthquake, note that a suburb of the city (Jerusalem) and more than half of Jerusalem were destroyed. Amiran et al. (1994): damage to the temple area, some workmen were killed. S Guidoboni et al. (1994) quote the historian Michael the Syrian: “The church of the Resurrection and that of the Golgotha and many places collapsed in the earthquake…” Shalem (1949): al-Aqsa collapses while being built by Omar. 746 01 18 morning C M-L Karcz (2004) refers to historic sources that describe damage to Jerusalem as well as to other sources that do not mention any damage. He suggests that the 746 01 18 event occurred in the Jordan Valley and the second one on 749/750, in Mesopotamia, and concludes that “It is possible that the intense damage in northern Israel and Jordan (possibly also in Jerusalem and Damascus) includes the collapse of structures weakened in the previous earthquake with epicenter more to the south.” Karcz (2004) mentions damage in: “the eastern and western parts of al-Aqsa compound […] destruction in Jerusalem and injuries to the descendants of Shadad al Aws, one of the Prophet’s companions. […] archaeologists … report extensive damage in Jerusalem, particularly to the central Ummayad administrative building, still under construction at the time of the earthquake…” Guidoboni et al. (1994): quote 13th-14th source: “… the worst damage occurred at Jerusalem” and a 15th source: “… there was a strong earthquake in Syria which destroyed Jerusalem”. Ambraseys (2005a): “Although it is possible that Jerusalem sustained some damage, the sources are silent. They do describe at some length the repairable damage caused to the Aksa mosque around its mihrab, but details about damage to other buildings and houses in Jerusalem are lacking.” Amiran et al. (1994): “Severe damage to al-Aqsa mosque, large Omayyad building south of the Temple area destroyed, people fled into the open ‘and stayed there 40 days’ ”. Shalem (1949): Damage to buildings in Jerusalem, but not as severe as in other places. Santa-Marie church destroyed. 757 03 09 S Ambraseys (2005a): “… it destroyed the repairs that had just been made to the Aksa mosque after the first earthquake. It was said that at the time of the third earthquake the platform of the mosque opened, allowing the sky to be seen; another earthquake following after this one closed the gap again.” Karcz (2004) referring to al-Aqsa: “Once completed, however, the mosque was hit by another earthquake (presumably in 757 A.D.)” 1033 12 05 before sunset 1068 03 18 and/or 1068 05 29 C S M-L L Amiran et al. (1994), Guidoboni and Comastri (2005): Damage to the city walls, the Temple area and many churches (including Holy Sepulcher) and convents, a part of David’s tomb and Ibrahim’s mosque collapsed, large number of people died. Ambraseys et al. (1994) citing a historic report: “Damage extended to Baniyas, where about 100 people were killed, and the same in Jerusalem”. Amiran et al. (1994): Damage to the roof of the Dome of the Rock. It is not clear to which of the two events (according to Guidoboni and Comastri, 2005) this damage should be related to. 1202 05 20 0240 N L Ambraseys and Melville (1988): “Jerusalem suffered relatively lightly […] at intensities not exceeding VI.” Guidoboni and Comastri (2005): slight damage in Jerusalem. 1458 11 08 or 16 S M Ambraseys et al. (1994): "In Jerusalem, the top part of the minaret over the Zawiya al-Dakah was thrown down and a dome near the church of the Holy Sepulcher was destroyed”. Amiran et al. (1994): mention that the Minaret of Omariyeh mosque near the Holy Sepulcher was destroyed in the earthquake of 1459. It is reasonable to relate the event of 1459 to that of 1458 which ruptured the northern Arava Valley (Klinger et al., 2000). Ambraseys and Karcz (1992): “Damage in Jerusalem, chiefly to tall structures, was widespread but repairable and undoubtedly not as serious as some of the contemporary exaggerated accounts want us to believe. The description of Jerusalem left by the pilgrims who visited the city shortly after the earthquake known to us, does not give the impression of a destructive earthquake…”. They suggest that this was a medium magnitude event of MS about 6.0, in many respects similar to that of the earthquake of 1927. 1546 01 14 afternoon C M Ambraseys et al. (1994) describe damage such as: “…the belfry of the Holy Sepulcher, which fell onto the church of the Resurrection”. Ambraseys (2005b): “…in Jerusalem damage was widespread but not serious. Some public buildings suffered repairable damage and a few people were killed in their shanty dwellings. Amiran et al. (1994): Damage to the minaret at Bab es-Silsileh and the Madrasa of Qaytbay. City walls damaged near the Golden Gate. The cupola of the Dome of the Rock collapsed, as did the cupola of the Holy Sepulcher and many towers. Most houses damaged. 12 people killed. 1557 02 C S Ambraseys and Karcz (1992): “An earthquake caused the collapse of a gun foundry, the forging house and ovens in Jerusalem.” 1712 06 16 C S Amiran et al. (1994): Three Turkish houses ruined. 1834 05 26 04:00 C M Amiran et al. (1994): Several churches damaged including the cupola of the Holy Sepulcher. Damage to the city walls, many houses and cisterns, which were emptied as a result of the earthquake. A minaret in the city and one on the Mount of Olives collapsed, as did the cupola of the Ascension. 1837 01 01 14:34 C L 1927 07 11 13 04 31.35N 35.25E ML=6.2 List of references is in ESM 2. Ambraseys (1997): In Jerusalem the earthquake was not very strong but it did some small damage. It is alleged that the minaret of the mosque at Kafr al-Tur, east of the city, was shaken down by the shock. Northern Dead Sea. Avni (1999): 24 people killed, 92 wounded and more than 600 houses damaged in Jerusalem and nearby villages. Details in the text and in Table 6. ESM 2 Notes Regarding other Historic Earthquakes This list refers to historic earthquakes (until to the 19th century) that were felt in Jerusalem but did not cause damage, doubtful earthquakes that were thought to have caused damage in Jerusalem, and doubtful reports of seismic damage. Date Comments 760-750 B.C. Guidoboni et al. (1994); Ambraseys (2005b): “…we could find no direct or indirect evidence that Jerusalem was damaged, and it is interesting that the details in Josephus about the effects of the earthquake on the temple are not supported by earlier sources that remain silent about damage anywhere in Judea and Israel." 92 02 28 B.C. Karcz (2004): It is imported from elsewhere in the Eastern Mediterranean: “So far no evidence was found of impact of the ca. 90 B.C. Apamea Kibotos earthquake on the Egyptian-Israeli-Levant coastal cities.” Guidoboni et al. (1994): The Apamea Kibotos (Turkey) occurred before 88 B.C. 64 B.C. Karcz (2004): “This event presents a further example of earthquakes imported into the Israeli catalogues on flimsy evidence. […] inflated elements of the story enter a catalogue as evidence of earthquake damage in Jerusalem…” 31 B.C Karcz (2004): ”… the textual evidence reflects a relatively modest earthquake with magnitude in the range of 6 - 6.5, rather than a major catastrophe. The earthquake motives found in assorted texts and tentatively attributed to the 31 B.C. earthquake are non indicative and may represent literary metaphors…” Overall, there are no direct reports of damage in Jerusalem by this earthquake. Shalem (1949) was not aware of any reports of casualties in Jerusalem. 33 This (or sometimes the 30 A.D.) is discussed in light of the Crucifixion event and allegedly caused a crack. Ambraseys (2005b): ”the earthquake at the Crucifixion is a spurious physical event.” 419 Guidoboni et al. (1994) cite original source that tells: “Many towns and villages in Palestine were reduced to ruins in an earthquake”. Other sources note that “the Holy places of Jerusalem and other areas were shaken by a very severe earthquake” and that “Jews, pagans and catechumens in Jerusalem were terrified, and all were baptized”. Amiran et al. (1994) note that this event was ‘severe’ in Jerusalem, but it is not clear if this relates to the shaking or to the damage. 551 07 09 Darawcheh et al. (2000) and Guidoboni et al. (1994) do not mention damage in Jerusalem in context of this earthquake (… the area to south from Tyre to Jerusalem was also preserved…”), while Amiran et al. (1994) note much damage in Jerusalem. We follow the former studies that rely on the original reports. c. 710, 713/4 Amiran et al. (1994), after Shalem (1949), after Sieberg (1932), mention damage to the eastern part of al-Aqsa, however, the largest known earthquake at that time is reported from northern Syria, between 28 February to 10 March 713 (Guidoboni et al., 1994) and no damage to Jerusalem is mentioned there. Karcz (1987) suggests that this report may refer to felt reports from Syria and that the source of felt report for Jerusalem is not clear. 749 or early in 750 Ambraseys (2005a): “The second earthquake, which occurred in 749 or early in 750, affected only Mesopotamia and presumably the adjacent part of southern Syria.” 750 – 780 Amiran et al. (1994): Two earthquakes caused severe damage to the Temple area. The second event ruined al-Aqsa. One of the events occurred on 3 May 765. However, Karcz (1987) notes that there is a need to verify the parameters, spread and damage of these events and that “The origin for description of damage to al-Aqsa is not clear”. Guidoboni et al. (1994) mention only the 9 March, 757, event in the Levant in that time period with no specific damage to Jerusalem. 808 Amiran et al. (1994) mention great damage to the church of St. Mary and the al-Aqsa mosque, but Karcz (1987) comments that “The primary documentation appears to refer to the long lasting effects of the 747 event”. 859 04 04 Amiran et al., (1994), after Shalem (1949), mention some damage to the temple area, but Guidoboni et al. (1994) refer to an earthquake in the Maghreb at that time period. 859 12 30 - 860 01 29 Guidoboni et al. (1994) mention that this event struck Antioch in northern Syria, and this seems to be too far (about 500 km) north of Jerusalem to have caused any damage there. 1016 Shalem (1949) and other sources mention the collapse of the cupola of the Dome of the Rock. On the other hand, Karcz (1987) comments that the occurrence of this event in Jerusalem appears to be in dispute. Guidoboni et al. (1994) do not mention this event at all. 1060 Amiran et al. (1994): The roof of the al-Aqsa mosque collapsed. Karcz and Lom (1987) examined the sources for this event and suggested that “all cited references converge upon a single listing, i.e., the report in Arvanitakis (1904) […] Unfortunately, this work does not provide any documentation for the 1060 CE event.” Note that similar damage was described also for the 1068 earthquake. 1105 12 24 Guidoboni and Comastri (2005): “… an earthquake frightened all the inhabitants of Jerusalem. Since no other effects are recorded, we can assume that it did not cause serious damage.” 1114 08 10 Guidoboni and Comastri (2005): An earthquake felt in Jerusalem but no effects mentioned. 1117 June 26 Amiran et al. (1994) note that many buildings were destroyed in Jerusalem, but this is not supported by Guidoboni and Comastri (2005) who relate the damage of this event to Scandelion, southern Lebanon. Karcz (1987) suggests assessing this event in relation to other strong earthquakes in northern Syria (1114-1115) or Europe (1117). c. 1150 Amiran et al. (1994): Slight damage in Jerusalem in the earthquake of 1160 and destruction of the monasteries of Mar Elias in the Judea Desert and St. John in the Jordan Valley. Nevertheless, Guidoboni and Comastri (2005), who analyzed the original source for this event, do not mention damage in Jerusalem. 1170 06 29 Guidoboni et al. (2004): “…the mainshock […] was strongly felt but without any damage of note”. 1545 Amiran et al. (1994) mention that the Tower of the Holy Sepulcher was damaged. And that the Church of the Nativity in Bethlehem was damaged. However, Ambraseys and Karcz (1992) do not mention an earthquake in 1545 and this report should probably be related to the earthquake of 1546. 1759 10 30 Ambraseys and Barazangi (1989): “The shock was rather strongly felt as far as Antioch, Aleppo, Jerusalem, and Gaza.” REFERENCES (for ESM 1 and ESM 2) Ambraseys NN (1997) The earthquake of 1 January 1837 in Southern Lebanon and Northern Israel, Annali di Geofisica XL:923-935 Ambraseys NN (2005a) The seismic activity in Syria and Palestine during the middle of the 8th century; an amalgamation of historical earthquakes.
