Morhange et al. (2006a:111) reported that following the 6th century CE coastal uplift associated with the 551 CE Beirut earthquake, sea level remained relatively stable until a subsequent rise was recorded by marine crusts preserved at Ras el-Bassit (Syria), located at an elevation of +60 ± 20 cm. above MSL (Mean Sea Level). These crusts are dated by six consistent radiocarbon measurements to between the 10th and 11th centuries CE (Sanlaville et al. 1997). Morhange et al. (2006a:111) further observed that two samples from Bouar and Khaizerane in Lebanon indicate a comparable, rapid, and likely tectonic relative sea-level rise of several decimetres. In a complementary study, Morhange et al. (2006b:91) suggested that “tectonic uplift of the coastal areas” may have taken place during the 10th–11th centuries CE (Pirazzoli 2005; Morhange et al., submitted).
