Eyjafjallajökull Volcano Eruption Quiz

What type of volcano is Eyjafjallajökull?

• Shield volcano

• Stratovolcano

• Cinder cone

• Lava dome

Which of the following best describes a primary hazard that occurred in April during the Eyjafjallajökull eruption?

• Seismic activity

• Minimal ash ejection

• Ash 250 million cubic meters rose 9km into the air as glacial melt mixed with magma

• Two craters formed

Eyjafjallajökull is located beneath which significant geographical feature?

• The largest river in Iceland

• The 6th largest glacier by the same name as the volcano

• The highest mountain in Iceland

• The deepest lake in Iceland

Explain how the plate boundary type contributed to the eruption of Eyjafjallajökull.

• The destructive boundary caused subduction and explosive eruptions.

• The constructive boundary along the Mid-Atlantic Ridge allowed magma to rise and form the volcano.

• The transform boundary caused lateral movement and earthquakes only.

• The convergent boundary created a trench and deep earthquakes.

Given the sequence of hazards and impacts in March and April, how might the combination of glacial melt and magma have influenced the secondary hazards observed?

• The combination had no effect on secondary hazards.

• The glacial melt and magma interaction increased the risk of jokulhlaups and flooding.

• The interaction only caused minor travel disruptions.

• The combination led to the formation of new volcanoes.

What was the estimated global financial loss to airlines in April due to volcanic activity, and how many passengers were affected?

• $1.7 billion loss affecting 10,000 passengers

• $2.5 billion loss affecting 5,000 passengers

• $500 million loss affecting 20,000 passengers

• $3 billion loss affecting 1,000 passengers

Which of the following was NOT listed as a management strategy during the volcanic event?

• Building emergency shelters

• Clearing ash from roads

• Constructing new airports

• Reinforcement of infrastructure

Why was Iceland particularly well prepared for volcanic activity, according to the document?

• Because of its experience and established monitoring systems

• Because it rarely experiences volcanic eruptions

• Because it has no active volcanoes

• Because of its tropical climate

Explain how international protocols and airport contingency plans contribute to global management of volcanic hazards. Use evidence from the document to support your answer.

• They help coordinate responses and minimize disruption to air travel worldwide.

• They increase volcanic eruptions.

• They reduce the need for local management.

• They eliminate the risk of respiratory problems.

A visitor centre was established in 2017 as a response to volcanic hazards. What was its main purpose?

• To educate about tectonic activity and their hazards

• To provide shelter for tourists

• To serve as a new airport terminal

• To monitor soil fertility
