Thumper truck

The first phase of the Jemez project is to assess the geothermal resources available, which was done over the past year and a half. In the coming months, they intend to drill very deep in the earth, between 5,000 feet and 6,000 feet, with the hopes of tapping underground heat to make electricity. Here is a "thumper truck," part of the seismic equipment needed to create a three-dimensional picture of the underground temperatures, aquifers, and fissures in the rock.
