Understanding Earthquakes

What is an earthquake?

Definition and types of earthquakes

Earthquake is a sudden, brief release of energy in the Earth's lithosphere that can cause widespread damage.

Types of earthquakes

  • Island Arc Assimilation
  • Tectonic Plate Boundary
  • Volcanic and VSEI

Effects of an earthquake on buildings and structures

Seismic design and retrofitting

Earthquakes can cause damage to buildings, bridges, and other structures that provide critical support for infrastructure.

Building Retrofitting

  • Seismic retrofitting is a process of improving the strength and resilience of buildings during earthquakes.
  • It involves modifying or upgrading building materials, designs, and construction techniques to mitigate damage from an earthquake.

Earthquake science and research

Research on earthquakes

Scientists investigate earthquake mechanisms, study the impact of earthquakes on different structures, and understand the processes that lead to earthquakes.

Case studies of notable earthquakes

  • 2004 Indian Ocean tsunami
  • 2011 Tohoku Earthquake in Japan
  • 1976 Tangshan earthquake in China

Understanding the science of earthquakes

Plate tectonics and Earth's surface

Earthquakes are caused by movement in the Earth's lithosphere, which is driven by plate tectonics.

The process of earthquakes

  • Subduction and collision
  • Divergence and convergent
