dvölutímabil
Dvölutímabil, also known as the "Devil's Interval," is a term used in Icelandic to describe a period of intense volcanic activity that occurred in the late 19th and early 20th centuries. This interval is notable for the significant number of volcanic eruptions that took place in a relatively short period of time. The term is often used to refer to the years 1890 to 1920, during which several major volcanic events occurred in Iceland, including eruptions at Katla, Grímsvötn, and others. These eruptions had significant impacts on the local environment and society, including disruptions to agriculture, changes in landscape, and potential hazards to human populations. The Dvölutímabil is a reminder of the dynamic and sometimes unpredictable nature of Iceland's geology.
