Field Trip 1
Tectono-stratigraphic history of the Saharan domain, southern Tunisia
21-24 November 2019
Participation Fee :
550 Euros (student)
650 Euros (academic)
750 Euros (professional)
Samir Bouaziz, University of Sfax, Sfax, Tunisia
Mohamed Soussi, University of Tunis El Manar, Tunisia
This two-day field trip will take place in the beautiful natural setting of the Saharan platform of southern Tunisia, which occupies a special position within the northern African margin. It is a privileged area for geodynamic reconstruction since the Paleozoic, because of the well identified morphotectonic domains and important sedimentary basin. Participants will learn about the complete stratigraphic sequences, which range in age from Late Permian to Quaternary, and the structural records characteristic of southern Tunisia. The sites have been carefully selected to better understand the Paleozoic orogenic cycle (paleotethys evidence), the Mesozoic tectonics cycle (Tethyan rifting) and the Cenozoic tectonics (evidence of Alpine-Atlasic orogeny). The circuit will also cover the only marine sequences of Late Permian in Africa outcropping at Djebel Tebaga of Medenine and the Mesozoic/Cenozoic subsidence basin (Tataouine, Chott, Jeffara). The complex uplift zone of Telezane and the fault system of Jeffara will be presented in particular in the context of the history of the Ghadames basin. This field trip welcomes senior and early-career scientists from all fields of the geosciences. The field trip guidebook will be available for download in summer 2019.

Field Trip 2
Neotectonics, archeoseismology and surface effects of historical earthquakes in Kairouan area

Kairouan city was built in AD 675 at the location of the Roman town Vicus Augusti, on the Roman “via” (road) that connects Hadrametum (now Sousse) to Amaedra (now Haïdra) passing by Aquae Regia (now Haffouz). The city is limited to the east by the small lake and swamp areas of Sebkhet Sidi El Hani and Sebkhet El Kelbia. Numerous villages can be found to the west built on alluvial fan deposits of the Wadi Zeroud and Wadi Merguellil rivers. Before the Arab conquest, this alluvial plain was the site of large fields with dense olive trees and gardens to the point that the Arab leader Okba Ibn Nafaa had to order deforestation to build Kairouan (Al-Bakri, XIth century, in. Mahfoud et al., 2004). The city became a large urban area during the Aghlabids dynasty (AD 800 – 909).
The region has a low level of seismicity with shallow instrumental earthquakes that hardly reach Mw 5.5 (in INM Catalogue). However, historical documents describe the occurrence of earthquakes with significant casualties and damage. This was the case for the Kairouan AD 859 earthquake that was responsible of numerous victims, homeless people, affected the great mosque and destroyed 13 villages in the region (Al Baghdadi, Al Tabari, Ibn Al Jawzi, Ibn Al-Athir, Ibn Adhari, Ibn Taghribirdi, Al Suyuti). This seismic event reported in historical manuscripts was however considered as dubious by other historians.
Recent field investigations conducted by the National Office of Mines in Tunisia in collaboration with the Institute of Earth Physics of Strasbourg (IPGS), and The National Institute of Heritage in Tunis “unearthed” historical documents that report the earthquake damage in Kairouan and Sousse areas during the 9th century (Bahrouni et al., 2019).
During the AD 859 earthquake the great mosque of Kairouan, the houses, fortifications and bridges suffered severe damage. The historical documents report that during the rule of the local governor Ibrahim Ahmed, important reconstructions and restorations were conducted in the city, the great Mosque in particular, bridges and battlements until Sousse city. Indeed, a poster exposed into the mosque courtyard shows the Mosque construction sketches before and after AD 859. The historians also report that the city (which reached about 100 000 inhabitants) suffered of severe water shortage due to the damage that affected the Cherichira aqueduct. Initially built at the Roman time and then retrofitted during the Aghlabids period, the aqueduct used to bring fresh water from the Oueslat Jebel (mountain) to Kairouan. Following the earthquake in AD 860, the Emir Ibrahim Ahmed decided the building of the large circular cistern called Feskiya Bab Tunis (literally the cistern of Tunis door).
This one-day field trip on 29 November 2019 will present the main features, damage and neotectonic observations associated with the AD 859 earthquake in Kairouan and Sousse. The itinerary will include the following stops:
- 08:00 Departure from the conference hotel in Sousse
- 10:00 Visit to the aqueduct damaged bridge at the Cherichira site
- 11:30 Departure to Kairouan

- 14:30 Departure to Sousse
- 15:30 Visit of the still visible stone engraving (in Arabic Koufi writing style) that commemorates the reconstruction of the southern wall of the battlements of Sousse and related fortifications in AD 859-860.
- 16:00 Visit of the old city Kasba
- 17:00 Departure to the conference hotel in Sousse
- 19:00 Dinner at the hotel
