Program Features

• Visualizes seismic events in the Iceland region
  using a visually pleasing 3D representation of
  geographic and seismic data.
• Allows the user to interactively select which
  seismic events to view, in regard to temporal and
  spatial context.
• Allows the user to freely view the seismic events
  from any angle and distance by modifying these
  preferences in real-time.

Visualization of Seismic Events

• Seismic events are represented as colored,
  semi-transparent spheres centered at the origin
  of the event relative to the geographical
  representation of the area.
• The size of an event sphere represents its spread
  (distance) factor.
• The color of an event sphere represents its
  magnitude factor. Weak events are almost white,
  and the stronger the event is, the more red it
  will appear.
• To allow the user to easily locate the geographic
  position of the event on the terrain surface, a
  narrow cone, centered at the event, is drawn
  through the terrain surface.
