Nepal is a densely populated area and the most recent major earthquake took place in 2015. A tectonics team from the Earth Observatory of Singapore has been studying the fault that passes through the Ratu River at the feet of the Himalaya, 140 kilometers south of Mount Everest, in the South East of Nepal. The goal of this EOS scientific research is to find out what sections of the fault are yet to break, and when this might happen again. raturiver.com

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 led by Judith Hubbard 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.
The film premiered at the 2016 Jaipur International Film Festival in NW India, about 1,000 km from Kathmandu. It also received a Sierra Nevada Award at the 2016 Mountain Film Festival in Mammoth, California, a Remi Award at the Houston International Film and Video Festival, in Houston, Texas, and a Nominee’s Prize at the China International Conference of Science and Education Producers, in Shenzhen. The film received over 79,000 Likes in the project’s Facebook page during the one-week online preview of the Nepali version. A one-minute field report video from the same expedition can be seen at:
