The Taupo Volcanic Zone is located on New Zealand’s North Island. It is 350 kilometres (217 mi) long by 50 km wide (31 mi) and lies over a subduction zone in the Earth’s crust. Mount Ruapehu marks its southwestern end‚ while the submarine Whakatane volcano (85 km or 53 mi beyond White Island) is considered its northeastern limit.[20] Many geysers in this zone were destroyed due to geothermal developments and a hydroelectric reservoir‚ but several dozen geysers still exist. In the beginning of the 20th

Limnic eruption A limnic eruption is a very rare natural disaster and also known as a lake turnover it is when there is a sudden release of inflammable gases (usually carbon dioxide) from a maar which is a lake in the crater of an extinct volcano‚ which is saturated with carbon dioxide from underlying magma reservoirs. A limnic eruption is a Geomorphological hazard because the occurrence of the eruption takes place first starting within the earth from the underlying magma reservoir. It is very rare

main causes of climatic alterations‚ natural cause is one of them. It refers to phenomenon such as forest fires‚ volcanic eruptions that cause tons of pollutants to our atmosphere‚ but also keeps the world in balance. For example‚ disasters such as volcano eruptions release at least 130 million tons of pollutants annually. Moreover‚ studies from the recent volcanic eruptions such as El Chichon‚ Mexico (1982)‚ and Mount Pinatubo‚ Philippines (1991) showed that the sulfuric acid liquid drops from these

Discuss the view that the impact of earthquake hazards depends primarily on human factors (40 marks) Earthquakes are an example of seismic activity caused by the build-up of tension at the three types of plate boundaries: destructive‚ constructive and conservative. The pressure is suddenly released as the plates jerk past each other‚ sending out seismic waves from the focus that travel through different parts of the earth. The movement of convection currents within the Earth’s mantle causing the
