27 June D10 4, p. 17 ...wind was from the west and carried with it heavy rainfall. We here in the Síða district saw a huge black sandy cloud
rise from Vesturgjá, which twisted and spun up over the mountains forming bolsters. This cloud dispersed sandy ash
containing some pumice-like lapilli scoria over Fljótshverfi and the eastern part of Síða. This was by far the most
voluminous tephra-fall to be dispersed over these districts. [This tephra fall is derived from the tuff cone to west of Laki
mountain. Thus, with reference to the dispersal direction of the tephra fall, west = N280◦ to 300◦E].
13 July D11 4, p. 21 ...the flow advanced from the west along the channel of river Skaftá into the narrows above Stapafoss waterfall ...from
there the river continued in a deep channel east-northeast along the Klausturfjall mountain. [This gives eeast-northeast
= N25◦ to 35◦E].
29 July D12 4, p. 26 ...this day rumble and boiling sound was first heard northeast of Mt. Kaldbakur, in the strike of a high mountain called
Blængur. [This gives northeast = N350◦E].
9 August D13 2, p. 67 ...that day a lava surge emerged out from Hverfisfljót gorge and advanced like running water out onto the sandur plain,
one mile [i.e., Danish mile = 7532 m] beyond so called Orustuhóll Hillock and from there due south until it stopped.
[This gives south = N180◦E].
14 Aug. D14 4, p. 28 The lava was rumbling northeast of Eiríksfell. [This gives northeast = N350◦ to 360◦E].
26 Sept. D15 4, p. 29 An additional column of fire and steam, which had been seen few times before [i.e., 18 July] far east-northeast from
Síða, due north of Lómagnúpur, but north-northwest from Öræfi district.
January
1784
D16 4, p. 32 Fire was still seen at the Austur-Landnorðursgjá. From Kirkjubæjarklaustur it was seen just north of the Mt. Þverárfjall.
It was more clearly seen from Öræfi district, due to its location. [The line Kirkjubæjarklaustur to Mt. Þverárfjall gives
east-northeast = N20◦ to 30◦E].
