Watch the spreading shockwave from an erupting volcano in Papua New Guinea

Watch the The eruption of Mount Tavurvur volcano on August 29th, 2014. Captured by Phil McNamara.

While this short video has impressed over 9 million viewers on YouTube, simultaneously volcanologists are making news by claiming that a long-held central textbook explanation of how volcanos erupt is grossly inaccurate. According to  ScienceDaily , in a typical explanation of  volcanic eruption,  like the one seen above, erupt when magma gushes out as narrow jets from deep inside Earth. But according to a new study from researchers at Caltech and the University of Miami in Florida, there is no evidence to suggest that is true. 

ScienceDaily reported that new seismology data are now confirming that “such narrow jets don’t actually exist,” says Don Anderson, the Eleanor and John R. McMillian Professor of Geophysics, Emeritus, at Caltech. In fact, he adds, basic physics doesn’t support the presence of these jets, called mantle plumes, and the new results corroborate those fundamental ideas.

“Mantle plumes have never had a sound physical or logical basis,” Anderson says. “They are akin to Rudyard Kipling’s ‘Just So Stories’ about how giraffes got their long necks.”
