Kenya's flower and vegetable industry, which employs tens of thousands of workers and contributes over a fifth of the country's GDP, is losing $3 million per day because ash from the Iceland volcano has grounded freight flights.

Clouds of ash from the Iceland volcano are forcing thousands of workers at farms near the Equator to down tools and robbing Kenya's flower and vegetable industry of $3 million per day.

The East African country freights 1,000 metric tons of roses, carnations, French beans, snap peas, and other produce daily on overnight flights to Europe. About 1/3 of the cut flowers sold in the European Union are grown in Kenya.

But the Kenyan, British, and Dutch airlines that fly from Nairobi have been grounded since Thursday, following flight bans due to risks to aircraft from volcanic ash spewing from Iceland's Eyjafjallajökull eruption.

Already $12 million worth of flowers and vegetables destined for European supermarkets have had to be destroyed or given away.

Astronomer Snaevarr Gudmundsson from Iceland was able to travel to within just a few kilometers from the Eyjafjallajokull volcano, and shared his incredible close-up images with Universe Today. "I stayed near the volcano from about 16:00 hours to 22:00 hours on Saturday and watched its impressive eruption," Gudmundsson said in an email to me. "Amazing event, awesome explosions of 1200 °C hot magma reaching ice and water. I shot more than 550 images during these hours of continuous enjoyment. Sounds ridiculous but its ever changing appearance was never boring."

The massive plume put on an impressive display - from lightning forming within the plume to an incredible amount of spewing ash. On one of following pictures you can see helicopter for size comparison of the plume.

Gudmundsson said he and other photographers were a safe distance from the eruption, but were a few kilometers away. "Nearby was a small river and its prominent sound prevented us from hearing much in the eruption itself except a loud roar from thunders from time to time," he said. "During daylight we even glimpsed some lightning but at dusk (the photo is taken at about 22:00 in the evening) they were easily spotted especially during active periods of explosions."

How volcanoes can change the world

Palisades, New York - The recent volcanic eruption in Iceland is stranding hundreds of thousands of air travelers at Heathrow Airport in the UK and other airports across northern Europe, due to its voluminous clouds of volcanic ash that can clog airplane engines and limit visibility.

However, this is by no means the first such volcanic eruption in Iceland to affect human activities. Long before the advent of air travel, the eruption of Iceland's Laki volcano in 1783-84 had profound effects on climate, not just in Iceland but around the globe.

Volcanologists Thorvaldur Thordarson and Stephen Self estimated that a comparable event in the modern era would release enough ash and other eruptive materials into the atmosphere that the resulting ash cloud and sulfuric haze would probably disrupt air travel over much of the Northern Hemisphere for about five months. But there were impacts well afield of Iceland and Europe at the time of Laki.

Iceland's farmers try to save herds from toxic ash

Skogar, Iceland - In Europe, the volcanic ash danger travels at high altitudes, but for Iceland's farmers the problem is very much on the ground.

Farmers across the region where the volcano erupted this week under the Eyjafjallajokull glacier have been scrambling to protect their herds from inhaling or ingesting the ash, which can cause internal bleeding, long-term bone damage and teeth loss.

Near Skogar, south of the volcano, the ash blew down from the mountain, blotting out the sunlight and covering everything - pastures, animals and humans - in a thick, gray paste.

Berglind Hilmarsdottir, a dairy farmer, teamed up with neighbors Saturday to round up her cattle, some 120 in all, and get them to shelter. In the panic, some of the animals got lost in the fog of ash, and the farmers had to drive around searching for them.

"The risk is of fluoride poisoning if they breathe or eat too much," Hilmarsdottir said through a white protective mask.

The fluoride in the ash creates acid in the animals' stomachs, corroding the intestines and causing hemorrhages. It also binds with calcium in the blood stream, and after heavy exposure over a period of days makes bones frail, even causing teeth to crumble.

Comment: Fluoride is poisonous? But why do they put it in our water supplies then?

Airlines lobby to reopen European airspace closed by Eyjafjallajökull

European airlines are taking "test flights" to see the effect of the ash on their aircraft in hopes to convince EU officials to reopen airspace. Now, officials from KLM say that everything went fine in their test flight, but I haven't seen any details about flightplans, altitude and all the sorts of info you'd want to see if you want to believe these test flights are representative. However, the president of KLM does have a bit of a point in saying that this ash is not unprecedented in the world of aviation - volcanoes are erupting along Indonesia, Alaska, Japan, Kamchatka and elsewhere around the world without widespread problems. However, the key question is how similar is this eruption to those that occur around the world all the time - and at what timescales could ash concentration change in the air over Europe. One other thing I don't know - and maybe somebody out there does - do most commercial pilots get trained on ash avoidance? However, there is still no word on when all of European airspace will reopen - but we may see up to 50% of normal flights by Monday.

Heat wave claims 80 in India


The Economic Times
Sun, 18 Apr 2010 21:50 UTC
A severe heat wave sweeping across the country, with temperatures of almost 44 C, has killed at least 80 people so far, officials said on Sunday.

Majority of deaths were reported in Orissa. A state government official said they were investigating reports of 53 deaths from various parts of the state. "District collectors have been asked to investigate and submit reports on other deaths," said Mr Bhimsen Gochhayat. Orissa has decided to shut down schools from next Tuesday, advancing the annual summer holiday.

Other deaths were reported from Uttar Pradesh and Madhya Pradesh. New Delhi recorded a maximum temperature of 43.7 degrees Celsius on Saturday, presaging a hot summer in the next two months in the nation's capital and other parts of northern and eastern India.

A special geological assessment team will be sent to Aceh to see whether the strong 7.2-magnitude earthquake this month had significantly altered the geography of the area.

Ridwan Djamaluddin, director for mitigation and regional development at the State Agency for the Assessment and Application of Technology (BPPT), said on Sunday that a team of 15 researchers from the BPPT was expected to arrive in Aceh Singkil district on Wednesday.

Residents on Banyak Island, off Aceh Singkil, which was near the epicenter of the quake on April 7, have claimed that the seabed has risen dramatically since the temblor. Undersea fissures were also reportedly spewing out mud and rocks.

"We will be observing the area and the team will be coordinating with the local government as soon as they arrive, collecting the data they need and making their assessment," Ridwan said, adding that Aceh Governor Irwandi Yusuf had invited the agency to visit the site.

"The Acehnese governor tells us that local people are starting to get worried and they are thinking of moving to a safer place," he said. "We are going to tell them if it is actually dangerous or not after conducting a thorough analysis."

It is well known that volcanic eruptions produce strong lightning. Less well known is why? Ordinary lightning in thunderstorms is not fully understood; volcanic lightning is even more of a mystery.

To investigate, a team of researchers from New Mexico Tech has traveled to Iceland to monitor the Eyjafjallajokull volcano--and they have found it crackling with electricity.

"On the evening of April 16th, there were some small eruptions producing ash clouds up to about 6-7 km, with lightning," says photographer Harald Edens. "The sky was nice and clear, so I was able to photograph the bolts from the town of Hvolsvollur using my Nikon D700 and a 80-200/2.8 lens."
