Iceland Volcanic Eruption

Why the volcano erupted

• Eruption caused by the diverging plates(North American Plate and Eurasian plate) at Mid Atlantic Ridge
  
  
• Iceland lies on a hotspot

Monitoring Volcanic Activity

What do they monitor??

•  Volcanic temperature
•  water level
•  lakes
•  mass movements like rock falls
• mud flow
• seismicity

Why do they monitor these things???

• Plot geology maps     
• Show changes before and after a volcano erupts
• To prevent death and illness
• Avoid affecting tourism, flights, business and daily activity

What materials are spewed out???

• Ash
• Smoke
• Lava
• Molten lava
• Rocks
• Many other solid, liquid and gases
• Gases: mostly steam but also includes poisonous gases(carbon monoxide, sulfur dioxide, hydrogen chloride)

Symptoms

• Earthquakes
• Rumbling Noise
• Animals acting weird
• More vents appearing
• However, the volcano may erupt without warning

What type of volcano is Eyjafjallajökull???

• It is a Stratovolcano, sometimes called a composite volcano
• Its is a tall, conical volcanoe with many layers of hardened lava, tephra and volcanic ash

Iceland Volcanic Eruption (Kimberly Kiong)

What I have learnt?

Group 1
The Iceland lies above a hotspot that results in an island of volcanism and geothermal phenomena such as geysers


This is due to the diverging plates of the North American plates and Eurasian plates along the faultline, Mid-Atlantic Ridge.

Group 2
What and why do the geologist have to monitor the volcanic activity,


What? Volcanic temperature, water level, mass movement like rock falls, mud flow, seismicity,

Why? Plot geology Maps- shows changes before a volcano erupts

It will affect:

Health, tourism, flight, business
Before a volcano erupts, there may also be an earthquake.

Group 3
What material spews out of the volcano?

Ash, smoke, lava and many other solid, liquid and gases. In the gases bit, they spew out mostly steam, but poisonous gases: carbon monoxide, Sulfur dioxide, carbon dioxide, hydrogen chloride escapes as well, and can suffocate people even before the ash hits them.It depends on how molten lava is ejected and rocks.

Severity of the situation:

Iceland Volcanic Eruption

The geological explanation of the conditions of the erupting volcano, Eyjafjallajokull, are...

•  the divergence of both the north american and eurasian plates
• a volcanic hotspot, which is a portion of the earth's surface that may be far from the tectonic plate boundaries and experiences volcanism
• iceland plume, an upwelling of hot rock in the earth's mantle beneath iceland

Geologists monitor a volcanic eruption because...

• prevent risks of injury and death
• plot geology maps and to show changes before an eruption
• business, flights, daily activities and tourism

Geologists monitor a volcanic eruption using...

• mass movements
• water level
• volcanic temperature
• rock falls, mud flows and seismicity

Materials that spew out from a volcano are...

• rocks
• lava
• ash clouds
• steam, smoke
• gases (poisonous ones such as carbon monoxide, sulfur dioxide, hydrogen chloride)

Some symptons which people rely on in preparation of an eruption are...

• rumbling noises
• more powerful earthquakes
• animals acting weirdly
• vents appearing across parks

Positive impacts of a volcanic eruption...

• rocks from the volcano contain nutrients useful for farming
• provide geothermal resources, where heat from the earth's crust is converted into energy which is very clean and nearly inexhaustible

Negative impacts of a volcanic eruption...

• Death
• Injuries
• Destruction of buildings and crops
• delay flights
• block roads
