Old maps help interpret Icelandic eruption

Authors


Abstract

The two maps on the cover show an interesting feature that helps explain one of the mysteries of the 1783–1784 Skaftár Fires fissure basalt eruption. Contemporary reports of the eruption refer to the “east northeastern fires” (fire fountains or other explosive activity), well to the east of the Skaftar Fires crater row. The fires recurred several times between May 1783 and May 1785 (see dates at top of Figure 1). That activity persisted for a little more than a year after the fissure eruption stopped.
