Summer A level Geography Case Study Research Project

Case Study Research Overview:

You will pick a tectonic hazard to study and create a PowerPoint presentation.

This presentation will be shared with you’re your new classmates, and used as revision.

1. Refresh understanding of tectonic Hazards

• Watch video on Volcanoes

• Watch video on Earthquakes

https://www.youtube.com/watch?v=e7ho6z32yyo

• Watch video on Tsunamis

2. Read the chapter “Hazardous Environments” (At end of document)

3. You will need to pick one tectonic event From list below:

Volcanoes

Volcanoes at Convergent Boundaries or Destructive Margins

❖ 1980 eruption of Mount St Helens – side eruption ❖ 1883 eruption of Krakatoa – loudest sound ever made on earth

❖ 79 A.D eruption of Mount Vesuvius - buried the ancient Roman city of Pompeii ❖ 1991 eruption of Mount Pinatubo – Predicted 60,000 people were saved

Volcanoes at Divergent Boundaries or Constructive Margins

❖ The 2010 eruption of Eyjafjallajökull - caused enormous disruption to air travel ❖ Nyamuragira erupts roughly every two years - Africa’s most active volcano

❖ Laki volcanic fissure in southern Iceland erupted 1783 – Killing a quarter of Iceland’s population

Hotspots

❖ The 2018 eruption of Kilauea – creation of chain islands – Hotspot under oceanic

plate ❖ Yellowstone – supervolcano - Hotspot under continental plate

❖ The 1963 eruption of Surtsey – creating a new a volcanic island - Hotspot under Constructive Margins

Earthquakes

Earthquake at Convergent Boundaries or Destructive Margins

❖ The 2010 Haiti earthquake - Death toll estimates 220,000

❖ The April 2015 Nepal earthquake - It was the worst natural disaster to strike Nepal ❖ The 1920 Haiyuan, Ningxia , China, earthquake – causing a landslide that buried

the village of Sujiahe ❖ 1960 Valdivia Earthquake - The world's largest earthquake

Earthquake at Transform Boundaries or Conservative Margins

❖ The 1989 Loma Prieta earthquake - It was the first major earthquake in the United States to be broadcast by live television.

❖ The 1906 San Francisco earthquake - Deadliest earthquake in the history of the

United States.

Tsunamis

[SUMMER - A LEVEL – GEOGRAPHY - CASES STUDY RESEARCH PROJECT] 2

Tsunamis are almost always caused by Earthquakes at Convergent Boundaries or

Destructive Margins

❖ The 2004 Indian Ocean earthquake and tsunami - one of the deadliest natural disasters in recorded history

❖ 2011 Tōhoku earthquake and tsunami - shifted the Earth on its axis by estimates of between 10 cm and 25 cm

❖ The 1600 BC Minoan eruption and Tsunami (Santorini) - Pyroclastic flow caused

Tsunami

4. Research your chosen event

5. Last create a PowerPoint presentation to use as revision material

Include:

Physical Factors

❖ What caused the event?

❖ Why is the event distinctive? ❖ Will it happen again?

❖ Primary and Secondary effect?

Human factors

❖ Was the event predicted or could have been predicted?

❖ What protection was there against the event? ❖ What could be improved in the future?
