How do seismic waves travel through rocks? How can satellites help predict earthquakes? The Science Why Science series explains how the science we learn at school is important in every aspect of our daily lives. Using case studies and investigations, the series describes the evolution of science and technologies that can improve our lives - or lead to new scientific challenges and differences.

In "Earthquake Prediction", we recognize the Earth's structure and how earthquakes occur. We discover the errors and depths, the science behind the seismic monitoring, and the role of earthquakes in causing the tsunami.

We also discover the difficult tasks of anticipating movements in the earth's crust.
