 and killing six people. 



1311. Fourth eruption of the Katla, on the 25th of January, com- 

 pletely ravaging the district of Lageyjarhverfi. Earthquake shocks on 

 the 10th and 11th of January destroyed fifty one farms.

1339. Earthquake on the 22d of May, in the south of the island, de- 

 stroying a number of farms above Skeidh, Floi, Holtamannahoeppr, 

 and between the Thj6rs4 and the Eystri Rang4. In the mountains of 

 Hengil a hot spring appears, with a circumference of 75 meters. 



1340. Third eruption of the Trolladyngja. 



1341. Seventh eruption of the Hecla, on the 19th of May, accompanied 

 by an enormous fall of cinders, which devastated several districts in the 

 surrounding country, while at the same time an earthquake destroyed 

 several farms. In the same year an eruption of the Oraefajokull is 

 mentioned. 



1343 (approximately). Eruption of the Randliulcamhar. In the adjoin- 

 ing valley of Thj6rs4rdalr eleven farms were completely destroyed. 

 Of some of them the ruins are still in existence. 



1349. Second eruption of the Oraefajokull, which devastated five 

 fertile districts (Herreder). After the ice covering the mountains 

 began to melt, the torrents thus formed swept away forty farms and 

 two churches, and those which bent their course towards the sea carried 

 such a quantity of sand and gravel that a beach had formed after the 

 eruption at a place where before the water had a depth of 56 meters. 

 Some lists give the dates of this eruption in the years 1350 and 1362, 

 respectively.

 ried westward, towards the sea, as far as M.f rar, and the eruption was 

 plainly visible at Snaefellsnes.

 same year saw the fifth eruption of the Trolladyngja and one of the 

 Sidhjolcull.
