began erupting in an event that culminated in an explosion so powerful it sent atmospheric ripples around the planet, multiple times. the blast was so loud it was heard in alaska, some 6,000 miles away. a blast that sent a plume of searing hot gas and ash 35 miles into the sky, higher than ever seen before. so this was big. but much of what happened that day has since remained a mystery, until now. scientists from the new zealand national institute for water and atmospheric research have been puttng the pieces together, and the picture that has emerged is truly mind boggling. the survey of the sea floor, shows the blast moved at least 2.3 cubic miles of rock, meaning this eruption is the largest recorded with modern methods. there s a 2,300 feet hole in the central crater that wasn t there before. and some 8,500 square miles around the volcano is now devoid of life, blanketed in a ghostly white layer of fine sediments. let s bring in kevin mackay who led the project for new zealand s n
where does your work now - volcano in indonesia. just quickly, where does your work now take i volcano in indonesia. just quickly, i where does your work now take you volcano in indonesia. just quickly, - where does your work now take you on the volcano investigating in tonga? the biggest issue we have found with our results is we didn t explore enough. this volcano was so much larger in eruption that what we even dreamt about. we didn t capture the image of it, there are still many cubic miles of material we haven t found so the next steps will be going back there and finding out how far this volcano affected the sea floor. , :, a far this volcano affected the sea floor. , :, :, ~i floor. best of luck with the work. thank you floor. best of luck with the work. thank you for floor. best of luck with the work. thank you for coming floor. best of luck with the work. thank you for coming on - floor. best of luck with the work. thank you for coming on the - thank you for coming on
are connected in the sense and this, are they connected? tte: are connected in the sense that and this, are they connected? ttre1: are connected in the sense that of plate tectonics. they are not directly linked but i will point out that this particular earthquake is very close to kra katoa. that this particular earthquake is very close to krakatoa. these same geological forces of plate subduction where you have one plate subducted under indonesia, that is what generates these stresses that cause earthquakes but these also generate the forces that calls these volcanoes that really affect indonesia as well. so volcanoes that really affect indonesia as well. volcanoes that really affect indonesia as well. , indonesia as well. so it s true then that once you indonesia as well. so it s true then that once you get indonesia as well. so it s true then that once you get a indonesia as well. so it s true then that once you get a tectonic- indonesia as well. so it s true then that once
