In the documentary film, they show how scientific teams from the EOS use a variety of techniques and technologies to collect data on what lies beneath the ground in the areas of the faults. Large trucks with vibrating devices, called VibroSeis, send sound waves into the ground, which then reflect off rock layers and underground formations. Data from these vibrations are collected by geophones, and are then processed to create a map of what lies beneath the earth’s surface. By viewing the faults at a depth of 5-15 km below the surface through these seismic survey map, the data collected by these researchers is crucial in helping detect future earthquakes and potential save lives. These seismic survey maps allow researchers to access critical data and view the faults at a depth of 5-15 km helping to detect future earthquakes and potentially save lives.
