SUMMARY:Urgent Data Analysis: Tracking Tornados in Real Time
DESCRIPTION:Workshop\n\nUrgent Data Analysis: Tracking Tornados in Real Ti
 me\n\nBording\n\nLightning talk: The time to escape from a tornado is meas
 ured in minutes and the swath of damage from an F5-rated tornado is measur
 ed in kilometers in length and up to a kilometer in width.  Weather radar 
 uses doppler measurements to see the possible energy density from a tornad
 o.  Radar is accurate with location but does not confirm if the tornado is
  on the ground.  New methods using recorded and processed seismic waves ca
 n actually detect if the tornado is on the ground and the approximate ener
 gy density.  Using high-performance computing in real time and sensors sys
 tems placed in a population density grid, the moving energy source locatio
 n can be tracked in real time across the earth surface.  Once the track is
  computed using urgent data analysis methods on high-performance computers
 , phone apps and visual computer messages can be sent as citizen alerts.  
 This would be a real-time and continuous process until the tornado lifts o
 r dissipates.  \n\nThe earth surface has low and slow velocities; energy a
 t the near surface travels deeper in higher velocity layers and these near
  surface waves travel faster.  The earth velocity model is built using pas
 sive seismic source activity over time and when a tornado action takes pla
 ce the compute-intensive back propagation algorithms can triangulate the e
 nergy track and path in real time.  Placing seismic receivers at or near s
 chools, hospitals and dense population areas can provide early warning.  O
 nce the passive data earth model is operational, areas not well-covered ca
 n be determined and additional sensors provided.  Model simulation animati
 ons demonstrating moving source wave propagation will be shown.\n\nTag: Ap
