Kemal ad-Din (Ibn al-Adim)
wrote that
a prodigious earthquake
struck on
Thursday, 20 October 1138 CE, with aftershocks continuing until
June 1139 CE. In
Aleppo, people were said to have evacuated
their homes and fled to the countryside. Stones were reported
to have detached from walls and fallen into the streets, and
the noise of the earthquake was described as terrifying.
The
citadel of al-Atharib collapsed, killing 600 Muslims,
but the governor [Emad ad-Din] survived with a few [other]
men.
Numerous places were said to have been damaged,
including Shiah, Tell-ĘżAmar, Tell Khalid, and Zaradna.
Many houses were destroyed, walls collapsed, and the two
walls, east and west, of the citadel [of
Aleppo?] collapsed.
In addition to the
sound of the earthquakes and the months of aftershocks, Kemal
ad-Din noted that there were 80 shocks in total.
