Ash from a volcano covers the entrance of a house as it continues to erupt on the Canary island of La Palma, Spain, Thursday, Oct. 28, 2021. Scientists estimate the volcano also has ejected over 10,000 million cubic meters of ash. The ash is jettisoned thousands of meters into the sky, but the heaviest, thickest particles eventually give way to gravity. They accumulate into banks that slowly cover doors, pour into windows, make rooftops sag. (AP Photo/Emilio Morenatti)
