The following are some of the environmental hazards that occur in different parts of the world.
Powerful winds like Tropical Cyclones cause havoc in the environment over which they prevail. The cyclones are formed by depression (areas of low pressure). they are called hurricanes in Caribbean, typhoons in Far East, Willy Willies in Australia and Tornadoes in North America.
these are violent whirling winds that form funnels of water that cause turbulence in the inland water bodies such as lakes. In Kenya, they have destroyed buildings (e.g. carrying away of classroom roofs), capsizing boats and destroying fishermen’s nets in Lake Victoria.
earthquakes cause a lot of damage to buildings, interfere with transport and communication and cause loss of life. Mild earthquakes are called tremors.
Earthquakes may also cause Tsunami like the one that occurred in 2004 in the pacific highlands and felt upto the East African Coast.
volcanic activities are usually violent resulting in damage to property and loss of life. For example, Mt. Nyiragongo in DRC erupted in 2000 killing more than 6000 people and altering the ecosystem.
Whenever gas leakages in industrial plants occur, a lot of damage is witnessed.
An accident on the nuclear reactor at Chernobyl in Russia in 1984 led to the death of 5000 people and hundreds deformed.
Fierce fires on residential buildings are usually caused by kerosene, stoves, candles or electric faults. Such fires cause deaths and destroy property. In 2000, an oil pipeline exploded in Nigeria killing 100 people in a radius of 20km.
Tractors and Lorries spill oils on roads, which not only make the roads slippery and dangerous but also choke vegetation and may kill animals if it gets in rivers.
In 2005, a vessel spilled 150 tonnes of crude oil into the sea at the port of Mombasa
Drought and desertification
Drought is the Deficiency of water in the ground, stream, lakes and reservoirs resulting in prolonged deficiency of rain e.g. the drought experienced in the year 1984.
It makes millions of people vulnerable to food shortages
