In other words when the hazardous threat actually happens and harms humans‚ we call the event a natural disaster.

the mantle. When these plates collide or slide past with other plates‚ earthquakes occur. After the main earthquake‚ an aftershock may occur as the rock masses settle down in new locations. Volcanic earthquakes are less common and occur when the volcano erupts. Volcanoes that explode violently produce acidic lava which blocks up the vents and prevents the pressure from escaping. When pressure is built up and then released‚ it can create an earthquake with a considerable magnitude. 3. Potential

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

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
