Iceland State Of Emergency
//A state of emergency has been declared in southern Iceland after another volcanic eruption on the Reykjanes Peninsula - the fourth since December.
Lava has reached the eastern defences around the small, evacuated town of Grindavik, local media said.
The powerful and fast lava flows began late on Saturday - but the authorities say they have since diminished significantly.
Activity around the fissure - initially 3km long (1.9 miles) - has dissipated.
Iceland's Meteorological Office said the streams of lava were still flowing on Sunday, but the rate at which they were moving had begun to slow down.//
A land of primeval beauty and one of my favourite places on earth - but I wouldn't want to be there now. These pictures are amazing!

Always wanted to go to Iceland as I would love to see the volcanoes, geysers, and hot springs. ( it's cheaper than a trip to Hawaii)
Ash not normally a problem with volcanoes that produce free flowing lava it is more a problem with the volcanoes under ice or water as this causes the lava to explode ( releases gas explosively as it cools to produce both ash and fine pumice) or where a Plinian eruption causes a large ash column which quickly collapses to generate pyroclastic flows ( like Vesuvius and most recently White island)
> Volcanic eruptions are one of the main causes of Global Warming and Global Climate Change.Why isnt Greta Thunberg over in Iceland leading protests against this volcano?
Because it isn't true: volcanic eruptions are not one of the main causes of global warming and global climate change. Saying so is nonsense, a classic climate-denial trope.

Volcanic eruptions are often discussed in the context of climate change because they release CO2 and other gases into our atmosphere. However, the impact of human activities on the carbon cycle far exceeds that of all the world's volcanoes combined, by more than 100 times.
To put it in perspective, while volcanic eruptions do contribute to an increase in atmospheric CO2, human activities release an amount of CO2 equivalent to what a Mount St. Helens-sized eruption produces every 2.5 hours and a Mount Pinatubo-sized eruption twice daily.
