Iceland's volcanic eruption has 'diminished markedly' and now is spewing far less ash, an Icelandic seismologist said Monday. 'Currently the eruption has diminished markedly,' Bryndis Brandsdottir of the University of Iceland told selfnews. 'The ash column does not rise above 3,000 metres (9,800 feet),' or less than half its original height, he added.
