Hawaii volcano spews 'ballistic blocks' into the sky in 'most energetic explosions yet'

A smouldering volcano in Hawaii has hurled large stones hundreds of metres and sent clouds of ash drifting over a number of communities. Plumes of ash from Kilauea rose as high as 3,000 metres above sea level, dusting towns as far as 18 miles away with ash and air pollution known as “vog”. Rockfalls within one of the volcano’s vents helped unleash more activity, geologists said, abruptly pushing out more ash.
