Yahya of Antioch reports that a terrible earthquake struck the area, such as had never been seen or heard of before. He lists numerous seismic effects, noting that half the houses in Ramla collapsed, several cities were affected, and a tsunami occurred at Akko. Yahya of Antioch appears to have given the wrong month; if one substitutes the preceding month (Muharram) for the supplied month (Safar), the date becomes 5 December 1033 CE.
