Ecuador volcano spews 10km ash column
Ecuador's Tungurahua volcano has spewed a 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 the blast occurred at 6.10 pm local time on Friday and was followed by a second, four-minute explosion and five lesser tremors.
The 5023-metre volcano, nearly 140km south of Quito, revived on February 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.
