|Exploration Activity Details|
|Location||Neal Hot Springs Geothermal Area|
|Exploration Technique||Reflection Survey|
|Activity Date||2011 - 2011|
A shallow seismic survey was conducted to gain a better understanding of the geology and structure of Neal Hot Springs and the surrounding areas. This study was conducted by students and faculty in geophysics field camps from the Colorado School of Mines, Boise State University, and Imperial College London.
Three profiles were conducted across Neal hot springs. The survey used a split, rolled over spread of geophones, meaning two arrays of geophones were used and when the end of one array was reached it would be moved to the next segment of the profile overlapping the other array at the half way point and extending past the end of the other array. This staggering and moving of the arrays allows the length of the entire profile to be much longer than the length of the arrays. The geophones were laid out at 5 m intervals and there was 96 live channels. A 60 kg accelerated weight drop was used as the seismic source. Shots were made every 5 m at the midpoints between geophones. The shots were laterally offset by about 2 m from the geophone array.
