1838 In the night between June 11 .and 12 an earthquake shook the north coast 

 of Iceland, between Hunafioi and Skjalfandi, which was not felt strongly 

 inland, but, like that of 1755, was very strong in the islands off the coast, 

 Grimscy and Drangey. The movement came from the sea and travelled 

 from the north-east to the west to the interior. This earthquake was felt 

 in the Sudurland at Eyrarbakki, June 12. Ill 



18G7 December 31, in the early morning there was an earthquake along the north 

 coast, particularly at Akureyri and Husavik, it reached to Vopnaf jordr, 

 on the east coast ; minor shocks followed in places to January 15, 1868. 

 There was not at that time any eruption in the north country, but from 

 August 27 to September 5 there had been an eruption in the Vatna Jokull 

 in the south-east of the island. II 



1872 A great earthquake was felt at Husavik and Akureyri in the night of April 18 ; 

 it was felt also at several other places along the north coast. II 



1874-5 From the week before Christmas to January 3, 1875, frequent but moderate 

 shocks occurred in Myvatnsveit and throughout the Nordurland, mostly 

 inland. Shocks continued near Myvatn to the spring, while eruptions 

 took place in Dyngjufjoll, January 3, and again March 29, and also in the 

 Myvatnsoraefa on February 18, but they were not of importance. I 



1882 October 29, there was an earthquake in several places on the north coast, 

 principally round Thistillf jordr, a bay near the north-east corner of the 

 island. 

 December 21. The same district was affected, particularly Akureyri. I 



1884 November 2. Sharp earthquakes occurred at Husavik, Kelduhverf, and 



Thistillf jodr. I 



1885 January 25, a severe earthquake at Kelduhverf and elsewhere along the north 



coast. Ill 

 1897 May 3. Earthquakes occurred along the western part of the north coast. I 

 1899 In the early part of this year there were frequent but not severe earthquakes 

 in Iceland generally. The strongest occurred on January 30 and 31, and 

 February 26-28, along the north coast from Bordeyri on the Hunafioi to 

 Akureyri. On the west coast it was felt at Holt, on the Onundarf jordr, 

 February 26, and on the same day at Reykjavik. On the 27th shocks were 

 felt at Eyrarbakki in the Sudurland. At Bordeyri the direction is stated 

 to have been south-east to north-west, at Grimsey the shocks were 

 thought to come from south and south-west. I 



Besides the three lists above abstracted, Mr. Thoroddsen's book contains 

 a general list of recorded volcanic eruptions and earthquakes in all parts of 

 Iceland, among which the following may be noted, which are not included 

 in the lists given above, as they occurred in Skaftafellsysla, which is not 

 comprised in the Sudurland, but lies to the cast of it. 



1721 On May 14 strong earthquakes were connected with the eruption of the 



Katla in the Myrdals Jokull ; they extended to Eyjaf joll and Fliotshlid 



in the Sudurland. 

 1727 August 2. There was a severe earthquake at Sandfell near the Orsefa 



Jokull in connection with an eruption of that volcano. 

 1783 June 1, a severe earthquake shook Skaftafellsysla ; the disturbance lasted 



till June 8, when the great Skaftargos, an enormous eruption from Skafta 



fell, commenced.
