A. D. 



991. 5th April ' On the 17th Muharram, great earthquakes at Damascus; 



to 1st May 1,000 houses fell, and many perished under the ruins. 



The shocks did not cease before (diem Veneris) the 14th 

 Qafar.' (Al Macin, edit, cit., page 316). The year 381, 

 A. H,, under which this is recorded, commenced 20th 

 March, A. D. 991, and the 17th Muharram, therefore, was 

 the 5th April, A. D. 991, and the 14th Qafar (the forty- 

 fourth day of the year), was 1st May, A. D. 992. This severe 

 earthquake is quoted (Brit. Ass. Catal., 1852, 17) as 

 occurring in August 992 on authority of Vattier's French 

 edition of LeMacin (Al Macin). I have not had access 

 to this edition, but the date is clearly given in Al Macin. —

 1111. September 1st — A great earthquake in Egypt recorded by Al Macin at the 

 third hour of the day, die Veneris, Friday, on the 3rd day 

 of Tut, 828. This is 828 of the era of the Martyrs, which 

 commenced 29th August, A. D. 284 (the accession of 

 Dioclssian). Tut is the first month of the year; therefore 

 the 3rd of Tut was the 1st of September. And, adding 

 283 to 828, the year was 1111, A. D. (Al Macin says 

 distinctly, die Veneris, Friday, which we have shown 

 above, was the 1st September, 1111 A. D. Comparing 

 this with J. Prinsep's tables, we find the 10th July of this 

 year was Monday; therefore the 1st of August was 

 Tuesday, so also 29, therefore the 31st August was 

 Thursday, and the 1st September, Friday, as before ; an 

 important and independent confirmation of the date, 

 given. — (Al Macin, edit, cit., page 369.) 

 2285. In the east ; said to have been widely extended. In the Brit. 



Ass. Catal., 1852, 35, this earthquake is quoted on the 

 authority of Abul Faraj. But I can find no mention of it 

 in that author ; indeed, as this treatise ends with 1284, it 

 is not possible he could have noticed it. I have been 

 unable to find other evidence of its occurrence. 

 2549, In 956 A. H. (=A.D. 1549), an immense earthquake at Qayin, 



in Khorasan (east of Persia) and killed 3,000 inhabitants.

 2619. "In 1028 A. H. (=9th December 1611 to 27th November 



1619), a terrible earthquake took place at Dughabad in 

 Khorasan. At several other places, throughout the whole 

 year, there had been earthquakes, but especially in Khora-
