Ecuador's Tungurahua volcano revives, spews 10-kilometre ash column
Saturday, April 5, 2014, 5:32 PM -
Ecuador's Tungurahua volcano has 10-kilometre column of ash after a powerful, five-minute explosion that shot pyroclastic material onto its northern and northwestern flanks.
Ecuador's geophysics institute said Friday's blast occurred at 6:10 p.m. local time and was followed by a second, four-minute explosion and five lesser tremors.
The 5,023-meter volcano, nearly 90 140 kilometres south of Quito, revived on Feb. 1, with eruptions that affected a third of Ecuador's provinces and temporarily closed a regional airport.

Tungurahua has been erupting sporadically since 1999. In 2006, a pyroclastic cloud killed four people and left two missing.
And since we're on the subject, we all know volcano erupt, but did you know they scream as well?
A team of volcanologists have discovered that before an eruption, volcanoes make a noise that resembles a scream.
