How do we predict earthquakes? They’re just like London buses, according to Rebecca Bell from Imperial College. In this podcast we discuss hazards, plate tectonics, and how they’re studied.
Dr Rebecca Bell is Lecturer in the Faculty of Engineering, Department of Earth Science & Engineering at Imperial College, London. In this podcast Dr Bell discusses her research into subduction zones, and slow slip earthquakes.
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 National Geographic 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 Gisborne, New Zealand earthquake and tsunami in 1947 is discussed. As a group debate, debate the importance of documenting human experience of earthquakes – what can we learn about living with hazards?
You work for a local authority in New Zealand. It’s your task to educate the community on Tsunami preparedness – providing information on how they happen, how to record their experience, and how to be prepared. Use these links below to help

This forms when two crustal plates collide
The large, broken up, pieces of the Earth’s crust and upper part of the mantle
This is formed when convergent boundaries collide, with one plate descending beneath the other
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
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
In this podcast, Professor Andrew Tatem discusses quantifying population movements and data skills in geography.
Professor Daniel Parsons explains
This book, written by two young people, manages to summarise a wealth of complex scientific findings
