In Iceland Moss is a common plant, widely grows in the mountainous region. The moss has a special characteristic of Iceland’s lava fields. However, the southern coast of Iceland over Eldraun Lava field is one of the most remarkable moss blankets in Iceland. The recorded history exposed a devastating eruption created the lave fields in Eldraun. In 1783 the Laki fissure and the adjoining Grímsvötn volcano poured out an expected 14 cubic kilometers of basalt lava and clouds of poisonous gases that contaminated the soil, killing half of Iceland's cattle and horses, and more than three-quarter of sheep. Moss can be easily damaged and potentially irreparably. Moss areas are particularly sensitive and damage caused by footprints and tire marks can take a very long time to heal.
However, in that year, nothing grew on the fields and no fish found in the sea. This was resulting in famine killed approximately a quarter of the island’s human population. Therefore, Laki’s eruption had even more widespread effects. In the years following the eruption, the climate across the Northern Hemisphere deteriorated. In the winter of 1784, the North America became the longest and one of the coldest on record. Thus, massive snowstorm hit the South, the Mississippi River froze at New Orleans and there were reports of ice floes in the Gulf of Mexico.
Moreover, huge Haze from the eruption floated east as far away as India weakening monsoon circulations and leading to drought and crop failures. Moreover, in 1784 the famine that hit Egypt, as a result of the eruption, killed approximately 1/6 of its population. Hence, the worst consequences were felt in Europe. The summer of 1783 was the hottest on record and a rare high-pressure zone over Iceland caused the winds to blow to the south-east. The poisonous cloud drifted across Europe, and its inhalation killed tens of thousands. In Great Britain alone, it caused some 23,000 deaths.
As the weather became hot, thunderstorms became more severe and large hailstones rained down from the sky causing injury and death to cattle. The following winter was tremendously cold and result in 8,000 extra deaths in the UK. Even though, in the during the spring thaw, Germany and Central Europe reported faced catastrophic flood damage. A series of crop failures in France and the causing poverty and famine eventually triggered the French Revolution of 1789-1799. Nowadays, the Eldraun Lava Field looks very serene and tranquil. The thick green moss has helped softened the rugged landscape, almost disguising Eldhraun’s violent past.
