Volcano Research Goes High-Tech

• GPS allows geologists to chart ground shifts
  without use of laser-ranging devices.
• Interferometric synthetic aperture radar-
  satellites zap radar signals to earths surface
  and shows how it bounces back

• Digital cameras connected to wireless computers
  monitir the volcanoes
• Spiderlike robots used by NASA goes in to craters
  to collect research

Volcano Research Goes High-Tech

• New digital seismometers are more sensitive than
  precursors
• New machines are not in Mt. St. Helens, but are
  in Califonia for earthquakes
• Costs 20,000 for 1 presiscion GPS unit
• One of the units placed near the volcano was lost
  along with a seismometer
• Its more accurate than consumer GPS devices, is
  smaller, and can powered by solar panels and
  batteries

Volcano Research Goes High-Tech
Is it worth it?
Where should they be put?
How is this information beneficial?
How will it help in the future to predict
volcanoes?
Who should have to pay for the research/
equipment?
