Fiji is geographically situated in one of the most natural disaster prone areas in the world; because of that a lot of natural hazards occur in Fiji. Some hazards occur as a consequence of tropical depressions and cyclones or as part of tropical weather condition that normally affects the region. Hazards such as landslides, flash floods, storm surges are most common.
The cyclone belt is where cyclones usually develop in the southern part of the Pacific. This is around the warmer waters closer to the equator at around 5 degrees and then die down when it reaches the colder waters around 25 degrees south of the Equator.
The Fiji Islands happens to be located within this area; between 11 degrees and 21 degrees south of the Equator.
What is Coastal Erosion?
Erosion is the process where soft shorelines (sand, gravel or cobble) disappear and land is lost. Erosion generally comes in two forms:
1. A Natural part of the coastal environment where a soft shore moves and changes in response to cyclic climate conditions and
2. Erosion can be induced by human interference of natural sand movement and budget patterns.... READ MORE
What is Drought?
Drought is a prolonged period of abnormally low rainfall resulting in a shortage of water. It is an insidious hazard of nature. It is often referred to as a "creeping phenomenon" and its impacts vary from region to region.
In the most general sense, drought originates from a deficiency of precipitation over an extended period of time--usually a season or more--resulting in a water shortage for some activity, group, or environmental sector.... READ MORE
What is an Earthquake?
As plates collide and grind over or past each other, stress builds up locally within the rock until the rock breaks along lines of weakness (faults). An earthquake is the vibration of the earth due to the energy released as the rock breaks.
Additionally some earthquakes can be caused by volcanic activity or underground collapse.... READ MORE
What is a Flood?
Inland flooding results from heavy and prolonged rainfall, when the water level in rivers and streams rises over the banks and inundates the surrounding land. There are three different types of:
1. Flash Floods occur within a few hours of torrential rains with little or no warning and dissipate rapidly. This is the most common form of flooding in Pacific Island countries.
2. Rapid-Onset Floods occur within several hours of heavy rainfall, can last several days and are specific to medium-sized river catchments.
3. Slow-Onset Floods occur gradually over a fairly long period of time and are only characteristic of large river systems..... READ MORE
What is a Tropical Cyclone?
A tropical Cyclone (also known as typhoons or hurricanes) is a violent rotating windstorm that develops over warm tropical waters warner than 26.5°C and located between 5° and 15°latitude.... READ MORE
What is a Tsunami?
A tsunami (a Japanese word meaning “harbor wave) is a series of waves, travelling at speeds of over 800km/h in the deep ocean and often going unnoticed. They travel harmlessly until they reach the shallow water of a coastline where they slow down and steepen, cresting to heights of more than 10m and can crash with devastating force across the shore, flooding low-lying areas and causing death and severe destruction....

A Category 5 cyclone’s strongest winds are VERY DESTRUCTIVE winds with typical gusts over open flat land of more than 280km/h. These winds correspond to the highest category on the Beaufort Scale.
Extremely dangerous with widespread destruction.... READ MORE
