Task: Conducting your own case study investigation…Use your classic 5W Enquiry technique and investigate the Japan 2011 Earthquake/Tsunami/Human Induced geophysical hazard…(note – structure of task sourced from www.geographyalltheway.com)…

Where did it happen?

Write a description of where it took place…
Include a map of the location with vital geographical points of interest…
Produce a sketch map of digital print off (or both) of the location (you should highlight the epicentre of the event)…

What happened?

Describe the management of the hazard event – before, during and after?
Planning, preparation, prediction, hazard mapping, evacuation, warnings.
Help with recovery, aid – local, regional and international, role of NGOs.
Finally – produce a one paragraph summary of the hazard event.

Revise what ar the 3Rs when it comes to responding to Hazard Events…

Rescue…

Reconstruction…

What’S it’s tectonic setting?
Produce a diagram of the tectonic processes involved

Subduction zone beneath Java, Bali and Lombok islands, Indonesia

Block-diagram showing a cross-section of the subduction zone beneath the islands of Java, Bali, Lombok and Sumbawa in Indonesia. The Indo-Australian tectonic plate (on the left) dives under the Eurasian plate (on the right).

When the Indo-Australian plate reaches a depth greater than 100km, the water it contains lowers the fusion point of the surrounding rocks, which creates magma. This magma is hotter and less dense than the rocks around and therefore starts to migrate towards the surface, where it eventually generates volcanism typical of subduction. The chain of volcanoes is more or less always at the same distance (around 300km) from the trench, which is the surface limit between Indo-Australian and Eurasian plates.
