Situation Update No. 17
this sounds like a huge bummer

After lying dormant for more than two centuries the Eyjafjallajoekull volcano in Iceland has now erupted twice in a month, bringing chaos to northern
Europe and destruction to its surroundings. Last night's eruption under a glacier, which spewed massive clouds of ash miles into the sky, was 10 to
20 times more powerful than the one last month, scientists said. But disruption could last for weeks because the volcano's last eruption lasted two
years from 1821 to 1823. Today's caused local rivers to rise by up to 10 feet as the ferocious heat melted the glacier, turning it to water which
gushed down the mountain. Iceland's main coastal ring road was closed near the volcano, and workers smashed three holes in the highway to give the
rushing water a clear route to the coast and prevent bridges from being swept away. Emergency workers rescued scores of tourists from around the
glacier as it spewed smoke and steam. Forecasters said Londoners will have an astonishing sunset tonight due to the Icelandic eruption. The Met Office
said a vivid “volcanic lavender” sunset was likely. Eruptions create what experts call a “volcanic aerosol” — a colourful mixture of ash and
sulphur compounds — in the stratosphere.
This scatters an invisible blue glow which, when mixed with the red light of the setting sun, produces a vivid crimson and violet hue. The eruption
could affect the UK until early next week, and cause changes to temperatures across Europe. “The problem is that we have an area of high pressure,
which is pushing the cloud from Iceland directly over Britain,” said Brendan Jones of MeteoGroup. “That will not change until early next week, so
as long as the volcano keeps erupting, we will have the ash cloud.” At 11am, the ash cloud was at around 20,000 feet and Mr Jones confirmed Britain
was unlikely to see much of it because the ash is so diluted. The most noticeable effect is likely to be at sunrise and sunset, when the particles are
illuminated. “The sky isn't going to go dark, and its unlikely we will see any deposits at all on the ground.” However, Mr Jones said previous
eruptions have caused major problems. “If you look back in history there have been some periods where the weather has been changed by big volcanic
eruptions like Mount Tambora and Mount St Helens.” In 1815 a huge eruption by Mount Tambora on the Indonesian island of Sumbawa spewed out massive
amounts of sulphur dioxide which combined with water vapour to form a sulphuric acid mist that reflected sunlight away from the earth. That caused
such a drop in temperatures that 1816 became known as “the year with no summer”.
