What do we use to measure earthquakes?

The measurement of earthquakes in our Southern California array is a 5 step process:

  1. The sensors are deployed at a geologically significant place of interest (typically in our study area this is in close proximity to the San Jacinto Fault Zone). We have to be careful that the sensors are above solid rock and away from any noise sources such as roads, bodies of water etc.
  2. The information is gathered in real-time using dataloggers. We currently use Quanterra dataloggers.
  3. The information from each station is sent to a hub at Toro Peak.
  4. The information is then sent to our station on Mt.Soledad and then down to us here at Scripps.
  5. The data is imported into our real time database (Antelope).

The animation below shows this process [coming soon]
