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
