DESCRIPTION:Abstract: Volcanic eruptions can have a dramatic impact upon h
 umans\, \nfrom the brutally direct through to the insidious role of gas an
 d ash on the global scale. Characteristic pre-eruptive behaviour has now b
 een\nestablished for a handful of frequently active volcanoes.  The most d
 amaging eruptions are\, however\, infrequent\, which presents challenges f
 or understanding monitoring data from very large volcanic systems. How sho
 uld we interpret\, for example\, deep earthquake swarms\, ground \ndeforma
 tion and gas emanations around huge subglacial volcanoes in \nIceland? The
 se volcanoes that have the potential to cause significant disruption and d
 eath in the UK. I will describe how exciting advances in \nEarth Sciences 
 have allowed us to use crystals in volcanic rocks as chronometers of pre-e
 ruptive processes. We can study ancient and damaging eruptions and resolve
  the likely magma storage depth\, \npre-eruptive gas release and timescale
 s of magma transport to within days\, or\, in some cases\, hours. These fi
 ndings can help to guide future \nvolcano monitoring activities and transf
 orm our ability to coexist with \nvolcanoes.
