Laki , volcano, 2,684 ft (818 m) high, S Iceland, at SW edge of the Vatnajökull glacier. Its eruption in 1783 was one of the more devastating on record, leading to the deaths of a quarter of Iceland's inhabitants (mainly due to a famine that resulted from the eruption's effects). Haze from the eruption spread over parts of Europe, where some experts believe it affected the inhabitants' health. Surrounding the crater are the Lakagígar series of c.100 volcanic rifts.
