wonder how much 'greenhouse' gas is being released by this monster?




The new island is more than one kilometre wide, two kilometres long and about 100 metres high



  • It was created by the volcano Hunga Tonga-Hunga Ha'apai, which lies 65km north of Tonga's capital


  • Its ash originally reached heights of over 4,500 metres, but is now only reaching 400 metres


  • 'As the ash is very wet, most is being deposited close to the vent, building up the new island,' the Lands and Natural Resources Ministry said


  • Ash and acidic rain from the eruption are deluging an area 10 kilometres around the volcano and killing of nearby vegetation

All volcanoes release about 1% of the human output.


Gas studies at volcanoes worldwide have helped volcanologists tally up a global volcanic CO2 budget in the same way that nations around the globe have cooperated to determine how much CO2 is released by human activity through the burning of fossil fuels. Our studies show that globally, volcanoes on land and under the sea release a total of about 200 million tonnes of CO2 annually.
This seems like a huge amount of CO2, but a visit to the U.S. Department of Energy's Carbon Dioxide Information Analysis Center (CDIAC) website (Carbon Dioxide Information Analysis Center (CDIAC)) helps anyone armed with a handheld calculator and a high school chemistry text put the volcanic CO2 tally into perspective. Because while 200 million tonnes of CO2 is large, the global fossil fuel CO2 emissions for 2003 tipped the scales at 26.8 billion tonnes. Thus, not only does volcanic CO2 not dwarf that of human activity, it actually comprises less than 1 percent of that value.
