Detailed explanation-1: -Consequences in Iceland An estimated 20–25% of the population died in the famine after the fissure eruptions ensued. (Some sources specify a death toll of 9, 000 people.)

Detailed explanation-2: -No human fatalities were reported from the 2010 eruption of Eyjafjallajökull. Those who lived near the volcano had high levels of irritation symptoms, though their lung function was not lower than expected.

Detailed explanation-3: -Sixty percent of all grazing livestock died due to the effects of the Laki eruptions. The “Haze Famine” as it is called in Iceland killed over 10, 000 people ( 22% of the population) from famine and disease.

Detailed explanation-4: -The Laki eruption of 1783 lasted over an 8-month period from June 8th 1783 to February 1784. Both the Laki fissure and Grímsvötn poured forth around 42 billion tons of basalt lava. They poisoned the air and soil with clouds of volcanic gases. The event has also been referred to as the Fires of the River Skaftá.
