al-Umari
Ambraseys (2009)
lists two al-Umari's in his reference section but does not specify which one he used in his catalog entries - e.g. for the
991 CE Damascus Quake
and the and the
1643/4 Jerusalem Quake(s)
.
I can't find much information on Yasin al-Khatib al-‘Umari
Muhammad Amin Al-Omari
was born in Mosul in in
A.H.
1150 or 1151 (1 May 1737 CE - 9 April 1739 CE)
My best guess is that Muhammad Amin Al-Omari is the source for the
1643/4 Jerusalem Quake(s)
as
Ambraseys (2009)
's entry for the
1643/4 Jerusalem Quake(s)
refers to al-'Umari as
a late author
. This, in turn, may suggest that Yasin al-Khatib al-‘Umari is the source for the
991 CE Damascus Quake
.
