Explosive Facts for your classroom

There are volcanoes on every continent, even Antarctica.

Did you know that over 80 percent of the Earth's surface is of volcanic origin? Volcanic gas emissions over hundreds of millions of years formed the Earth's earliest oceans and atmosphere, which supplied the ingredients vital to evolve and sustain life. Volcanic eruptions have produced mountains, plateaus, and plains, which eventually weathered into majestic landscapes and formed fertile soils.


Aotearoa New Zealand’s dramatic landscape is due to our highly charged natural hazards such as volcanoes, earthquakes, tsunami, floods and landslides.  Our volcanoes are world renowned for their frequency of eruptions and volumes of material ejected.

Many volcanoes, in Aotearoa New Zealand such as Taranaki and Ngauruhoe have the classic cone shape but there are many other volcanoes that are not so easily detected.  Tarawera looks like a collection of hills with flat tops rather than a volcano that ‘blew its top”. Lake Taupo is in fact a caldera created by a supervolcanic eruption which occurred approximately 26,500 years ago.


Sources say, some 1,500 volcanoes are still considered potentially active around the world today.  Most of the world's most active volcanoes are positioned around the ring of fire, a 25,000-mile long, horseshoe-shaped zone that stretches from the southern tip of South America across the West Coast of North America, through to Japan, and on to New Zealand.
