 Technology	  	  The	  goals	  of	  this	  session	  are	  to	  develop	  the	  science	  and	  technology	  for	  a	  GNSS	  tsunami	  early	  warning	  system	  that	  is	  intended	  for

 resultant	  tsunamis	  impacting	  coastal	  communities	  and	  infrastructure	  across	  the	  Indo-­‐Pacific	  region.	  While	  investment	  and	  collaboration	  to	  strengthen	  the	  early	  warning	  and	  mitigation	  systems	  have	  improved	  measurement	  and	  modelling	  for	  ‘distant’	  tsunamis	  generated	  from	  earthquakes	  far	  across	  an	  ocean	  basin	  the	  science	  and	  technology	  now	  exists	  to	  provide	  near	  real-­‐time	  visualization	  as	  tsunamis	  propagate	  around	  the	  world	  and	  to	  reduce	  significantly	  the	  risk	  from	  tsunamis	  generated	  near	  the.	  This	  is	  accomplished	  through	  the	  use	  of	  real-­‐time	  GNSS	  measurements	  in	  combination	  with	  other	  observations	  that	  measure	  both	  ground	  displacements	  generated	  by	  large	  earthquakes	  and	  disturbances	  in	  the	  ionosphere	  from	  the	  propagating	  wave.	  	  The	  presentation	  and	  discussion	  of	  the	  session	  are	  focusing	  on,	  but	  limited	  to,	  science,	  technology	  and	  data	  associated	  with	  the	  development	  and	  deployment	  of	  a	  real-­‐time	  GNSS	  tsunami	  early	  warning	  system.	  	  Special	  Session	  4:	  Nepal	  Earthquake	  	  The	  recent	  M7.9	  earthquake	  that	  struck	  Nepal	  devastated	  that	  country	  and	  caused	  in	  excess	  of	  7000	  deaths.	  	  This	  late-­‐breaking	  session	  will	  accept	  papers	  that	  deal	  with	  the	  science,	  data,	  models,	  and	  response	  to	  that	  earthquake.
