is Lecturer in the at Imperial College, London. 聽In this podcast Dr Bell discusses her research into subduction zones, and slow slip earthquakes.聽

Learning activities

Listen to the podcast and make notes on the following questions:

  • What are oceanic plates?

  • What is recurrence interval?

  • What are the things that affect the stress in fault lines?

  • What is a slow slip event?

  • Why are these difficult to study?

Watch this report on the 2011 Tsunami that took place in Japan. Explain how did it occur?

Study these news articles related to the event. It has been seven years since the event. How has Japan prepared for future earthquakes and tsunamis?

In this podcast, the historic is discussed. As a group debate, debate the importance of documenting human experience of earthquakes 鈥� what can we learn about living with hazards?

You work for a local authority in New Zealand. It鈥檚 your task to educate the community on Tsunami preparedness 鈥� providing information on how they happen, how to record their experience, and how to be prepared. Use these links below to help

Key Words

Convergence boundaries
This forms when two crustal plates collide

Tectonic plate
The large, broken up, pieces of the Earth’s crust and upper part of the mantle

Subduction zones
This is formed when convergent boundaries collide, with one plate descending beneath the other

Fault lines
A facture that occurs when tectonic plates move or shift – this is where earthquakes are likely to occur

Slow slip event
Slow creep in faults that occur over weeks, or months rather than seconds

Tsunami
A tsunami is a series of waves caused by earthquakes or undersea volcanic eruptions

Seismic reflection imagining
Using seismology to estimate the properties of the Earth’s subsurface from reflected seismic waves
