Transcript of Eruption of Eyjafjallajokull Volcano, Iceland

The Eruption of Eyjafjallajokull, Iceland
Background
Background
Eyjafjalljokull erupted
between April
and

May 2010
.
Shallow earthquakes
were registered by seismographs in early March.
In early April there was an
effusive eruption of basaltic lava
.
In some places the
ridge opened up
to produce lines of erupting lava.
Impacts... In Iceland
500 farmers
and their families had to be
evacuated
from the area.
The
fluorine rich volcanic ash contaminated
local
water supplies
, making it unsafe for cattle or humans to consume
Several
main roads
had to be
closed
as the thick ash that covered them made it dangerous to drive.
Impacts... Environmental
The volcano put a maximum of
30000 tonnes of CO2
into the air
every day
, but as
2.8 million tonnes less
of carbon dioxide was
emitted
by humans due to the
lack of air traffic
, this has had a negligible effect.
Livestock
had to be
evacuated
off pastures surrounding the volcano, as they were at risk of digesting fluoride form the volcanic ash, which could cause lameness and haemorrhages.

Located in the
south of Iceland
Lies on the
Mid Atlantic Ridge
, a constructive plate boundary between the
North American

and

Eurasian plates
.
The two plates are
moving apart
- the Eurasian plate is moving eastwards, while the North American plate is moving west towards the USA.
Elongated Ice-covered
Stratovolcano

2.5km wide
summit caldera
Impacts... on Airlines
The worldwide airline industry
lost £130 million a day
, and airports lost a total of
£80 million
over the six and a half days.
Around
107,000 flights
were
cancelled
, affecting over
10 million passengers
.
In the UK
13 travel firms collapsed
during the summer of 2010, with the ash clod believed to be a contributing factor.
3000 tonnes

of flowers
were
destroyed
in Kenya as they were unable to be shipped to Europe, this was particularly devastating as
20% of the Kenyan economy
is based upon the export of cut flowers and green vegetables.
Over 50,000 Kenyan farmers
were
temporarily unemployed
, as they couldn’t sell their beans and peas.
Zambia’s
flower and vegetable industry
lost £98,000 a day
.
The
Eurostar
carried an
extra 50,000 passengers
between the 15th and 16th of April 2010, with
6 extra services
put in place on Monday the 19th of April.
Impacts... on Other Businesses
Backgroud
It was
less active
than others in Iceland's eastern volcanic zone.
The
last historical eruption
of E15 was from
December 1821 to January 1823

It measured a
VEI 4
.
Management
In response to the impact of the flower industries being majorly affected, the industry survived 4-7 days disruption, by
diverting flights
to Spain or Greece, and then using land transport but at up to
80% more in freight costs
.

Management
Many national centres and industries had already held
systems to sense
the structure of volcanic ash clouds and how
dense and high
they are.
The
UK National Centre for Atmospheric Science
has a mobile Lidar system which uses radar.
The
portable
system also meant that planes would not have to fly to see if it was safe to be in the air.
The system is based on the
ground
and at a
distance
from the volcano.

Management
This was a strategy to pick up the pieces and stop the industry from losing as much as
$3 million a day
.
Any longer disruption would have
spelt disaster
for the flower industry and begun to seriously disrupt the fruit and vegetable trade.
Southern parts of Europe were
not effected
largely by the Ash clouds, meaning the transportation of the flowers was able to be done.
