Volcanic Eruptions: Case Study (MEDC) Flashcards
What facts make Japan an MEDC and a good natural hazards manager?
GDP(Ph): $37,000
It experiences many natural hazards yearly due to tectonic setting
Outline the tectonic setting of Japan
Sits between 3 plate
What were the impacts of the Mount Ontake eruption?
57 people killed and 40 injured
Ash descended into streams damaging ecosystems
Villages on the mounting damaged by ice melt and ash (40-50cm)
What were the responses to the amount Ontake eruption?
Immediate response of hikers being sheltered in hiking hut
1000 troops deployed to help the hikers on mountain
Helicopters sent to villages on mountains
What can be learnt from the Ontake eruption?
Despite development of countries, volcanoes can still cause significant damage to countries. However the lack of preparation from Japan in the run up in reaction to tremors was a human fault and suggests that volcanoes impacts aren’t completely dependant upon the eruption itself.
What and when is second case study for a volcano eruption in an MEDC? Correct spelling!
Eyjafjallajökull, Iceland (2010)
Describe the volcanic and tectonic setting of the Eyjafjallajökull volcano?
Stratovolcano with a magma chamber fed by the MAR. It has a glacier on it.
What were the impacts of the Eyjafjallajökull eruption?
> Glacier melt caused a major flood but no real damage
11km high ash cloud caused major air travel dangers as transported by ocean currents and jet streams over Atlantic
Kenyan economy partially hooted due to exports on hold
Fluoride water contamination for livestock
Increased cost of other transport methods
How many flights were cancelled as a result of the eruption?
How great was the daily cost?
How many people stranded?
107,000 cancelled
£130Million daily cost
5 million stranded
How was the Kenyan economy affected by the Eyjafjallajökull eruption?
It depends upon exports of vegetables and the eruption halted exports leading to 50K temporary unemployment.
How many people were evacuated in total in Iceland due to the ash and flood threat?
1200
What was the responses to the Eyjafjallajökull eruption?
Cancelled flights, if not then there could have been many deaths
Local Evacuation and face masks
What and when is the case study for a volcanic eruption in an MEDC?
Mount Ontake, Japan (2014)
