 There are no old records of earthquakes in this area available. 



AD. 



1663 Earthquake at Reykjanes Skaga. No date. I 



1706 The great earthquake which devastated Arnessysla in the month of April 

 would seem to have been felt, though faintly, near the Faxafloi, as it is 

 mentioned in Mr. Thoroddsen's list of earthquakes in that district, but 

 all the details mentioned by him there refer to localities in Arnessysla. I 



1724 The earthquake in Arnessysla in August was felt at Reykjavik. 



1754 Earthquake at Krisuvik. No date indicated. I 

 1825 January 18 and 21, shocks at Reykjavik. II 



1860 September 20, earthquake shocks occurred at Reykjavik ; the direction was 

 south-west to north-east. 

 In the middle of June and between December 30 and 31 weaker shocks were 

 noticed, having the same direction. I 



1864 Earthquake in Reykjavik on February 16. I 



1868 Frequent and strong shocks occurred in the beginning of November at Reyk- 

 javik and Borgarf jordr. They were also noticed in the Sudurland, Novem- 

 ber 1 to 7. II 



1878 The earthquake in the Sudurland, February 27, was felt at Reykjavik ; there 

 were three shocks. 



1870 Strong earthquakes at the end of May at Reykjanes Skaga and Krisuvik. 

 At the same time there was an eruption in the sea off Reykjanes, near the 

 Geirfuglaskeri, the last breeding -place of the Great Auk. 



1887 The earthquake in the Sudurland, October 28, was felt at Reykjavik ; there 

 were two not very strong shocks. I 



1889 October 13, strong shocks were felt at Reykjavik and other places round the 

 Faxafloi. These were scarcely felt in the Sudurland, which had suffered 

 from an earthquake earlier in the spring. 



1S96 The great earthquakes in the Sudurland in August and September were felt 

 at Reykjavik, Borgarjordr and elsewhere round the Faxafloi. I 



1899 The extensive seismic disturbance in the Nordurland after New Year was 

 also felt round the Faxafloi, particularly at Reykjavik, February 27. I 

 Several earthquakes in the Sudurland at various times were felt about tho 

 Faxafloi, but were not destructive. 



A List of destructive earthquakes in the Nordurland. 

 As regards this area, too, early records of earthquakes are almost absent. 



12(0 A great earthquake in the North, at Flatey, an island in the bay called Skjal- 

 fandi. No date. II 



1618 Constant earthquakes continued night and day from harvest time to Christ- 

 mas. Damage was done at Thingeyjarthing. 



1724 Earthquake, May 17, in Myvatnsveit in connection with a series of volcanic 



eruptions in that district which lasted to 1730, during which time earth- 

 quakes were frequent. 



1725 Earthquake in Myvatnsveit in connection with the first eruption of the 



volcano Leirhnukur, on January 11, and again April 19, in connection 

 with the eruption of Bjarnaflaga. 

 1 728 Several earthquakes occurred in the Myvatnsveit in connection with eruptions 

 from four different craters in the district. The strongest was on April 18, 

 but many minor shocks were noticed all through that year. I 



1755 September 11 to 24, a series of earthquakes affected the north coast of Iceland 



along the shores of Skagafjordr, Eyjafjordr and Skjalfandi. Damage was 

 done at Husavik and several minor places. The disturbance reached 

 Grimsey Island to the north of Iceland, but there was no earthquake in 

 Myoatvisveit nor in other parts of Iceland. Mr. Thoroddsen mentions that 

 on October 17 commenced a violent eruption of the Katla in the Myrdals 

 Jokull, south of Hekla, near the coast, and he reminds his readers that 

 the famous earthquake at Lisbon occurred a fortnight later. Ill
