Earthquake

Waves produced by an earthquake.
This is a photo.
How to measure earthquakes accurately.
  • occur due to movement in tectonic plates
  • only seconds of notice, 5-10 seconds
  • [p waves] are much faster than [s waves] and the actual waves that cause the earthquake.
    • earthquakes travel at about the same speed as data networks
  • can be measured by motion (on surface or underground) and pressure (underground)
    • downside of underground monitoring is 1) power and 2) transmission
      • can use repeaters or solar power to solve these issues
    • advantage of being underground is distance from noise (such as animals and humans) and being closer to the source of the earthquake
    • being attached to rock is good

Tsunami

This is a photo.
Possible methods to predict and measure tsunamis.
  • in the deep sea pressure sensors are used to measure the relatively small sea-level change (in centimeters)
  • nearer to shore, where waves start to form, altitude could be measured by buoy
  • travel at hundreds of miles per hour
  • tsunami headquarters in Hawaii
  • notification could be minutes to hours in advance depending on distance from source of tsunami
  • height/speed of wave reduces with distance
