Lava and ash from Ecuador's Tungurahua volcano forced the closure of Guayaquil Airport until Saturday afternoon, an airport spokesman said Friday. The glacier-capped, 16,478-foot (5,023-meter) volcano has erupted periodically since 1999, with major eruptions occurring in August 2006 and February 2008, the government's emergency management agency was quoted as saying by CNN. Officials evacuated the towns of Cusua and Juive Grande in central Ecuador, the emergency agency said, but no injuries or fatalities had been reported. No further evacuations were planned, the agency said.
