The Ratu River Expedition

The Ratu River Expedition is a 25-minute film featuring the research on Nepal earthquakes by the Structural Geology group at the Earth Observatory of Singapore. The film was written and directed by Isaac Kerlow, and it shows how the scientific team uses a variety of techniques and technologies to collect data on the field for later analysis. This includes a massive truck called the EnviroVibe which vibrates the ground between 10 to 300 pulses per second, sending sound waves up to 2 kilometers deep. The sound waves reflecting off the rock layers are used to visualize the faults and underground structure. Watch the film here:
