On 4 May, the Icelandic Met Office reduced the Aviation Color Code at Öræfajökull from Yellow to Green due to signs of reduced activity. Since September 2017 there has been less earthquake activity, stable hydrological and geochemical measurements, and reduced geothermal heat output. There has been possible minor ongoing inflation, but no signs of an imminent eruption.
Iceland and its volcanoes:Iceland has the land area of Virginia and the population of Virginia Beach (about 260,000 people). The country has the highest literacy rate (100%) of any nation in the world. Its history has always been closely related to volcanoes and knowledge of many volcanic eruptions since the middle ages are preserved in accounts.
First settled by Vikings in the 9th century AD, Iceland established its own parliament in 930 and recorded its first historical volcanic eruption only a few years later. After a golden age of literature in the 12th and 13th centuries (when the sagas were written), natural history reporting reached a low around the 15th century. In the years 1707-09 a third of the population died from smallpox, and the 1783-84 Laki eruption killed a fifth of the remaining population by famine. Iceland gained sovereignty from Denmark in 1918 and complete independence in 1944.
Iceland is noted for subglacial and regional fissure eruptions related to the rifting process between the separating plates.

Исландия, земля льда и огня, – это настоящий рай для вулканологи. В немногих мест на земле геологии и истории человечества являются настолько тесно связаны с вулканизма в Исландии. Остров владеет своим существованием большого вулканического гиперобъекта, сидя на середине океаническом хребте, уникальные настройки. Плита граница между американским и Евразийской тектонических плит пересекает Исландии с юга на север и распространяя процесс может непосредственно измеряется и наблюдается на землю.
