Natural Hazards

A natural hazard is a threat of a naturally occurring event that will have a negative effect on people, their assets or the environment.


Natural hazards, including earthquakes, volcanic eruptions, liquefaction, landslides, coastal erosion, floods, droughts, cyclones and tsunami can often result in disaster to communities. Climate change can also exacerbate natural hazards, so their effects can vary with time.

Preparedness, protection, emergency response and recovery are the four pillars of our disaster resilience response offering. With more than 40 years’ experience in natural hazard and natural hazard risk management, Tonkin + Taylor has a proven capability at supporting clients through all stages of disaster resilience for events of almost every size.
