DESCRIPTION:Speakers: Dorianne Tailpied (Nanyang Technological University\
 , Earth Observatory of Singapore\, Singapore)\, Anna Perttu (Nanyang Techn
 ological University\, Earth Observatory of Singapore\, Singapore)\, Siow K
 ay Wong (Nanyang Technological University\, Earth Observatory of Singapore
 \, Singapore)\, Benoit Taisne (Nanyang Technological University\, Earth Ob
 servatory of Singapore\, Singapore)\, Sundod Chulalak (Nanyang Technologic
 al University\, Earth Observatory of Singapore\, Singapore)\, David Whilld
 in (Nanyang Technological University\, Earth Observatory of Singapore\, Si
 ngapore)\n\nWith global increases in population and air traffic\, our abil
 ity to forecast when and where a hazard will occur is of prime importance.
  In the case of volcanic eruptions\, forecasting is not limited to when an
 d where an eruption will take place\, but also when and where the impact o
 f such an eruption will be felt. Cross-boundary volcanic ash from explosiv
 e volcanic eruptions is hazardous. The dispersal of volcanic ash could be 
 modeled\, however the level of uncertainty drastically depends on our know
 ledge of the eruption itself. Critical parameters are the duration of the 
 eruption as well as the height of the associated eruptive column. With tho
 se 2 parameters you can simulate a range of plausible ash dispersal scenar
 ios. Such parameters could be retrieved by monitoring\, research sensors o
 r an array deployed on the flank of the volcanoes. However\, in a region w
 ith hundreds of active or potentially active volcanoes this is not always 
 possible. We would like to demonstrate a few recent examples for which the
  IMS and IMS-like (installed in Singapore) infrasound stations were used t
 o extract eruption source parameters.\n\nhttps://conferences.ctbto.org/eve
