Martin Redfern, and the BBC Radio Science Unit, have just produced a terrific half-hour radio program about long-term monitoring on Etna!!
You can listen to the show online as a podcast at http://www.bbc.co.uk/radio4/science/thematerialworld.shtml
After a week, the url will become http://www.bbc.co.uk/radio4/science/thematerialworld_20081120.shtml as the next week’s show replaces it on the front page.
You can also read Martin’s personal account of the visit at: http://news.bbc.co.uk/1/hi/programmes/from_our_own_correspondent/7729440.stm
