|About the Test Facility|
The seismological observatory was founded in early 1970s to cater for the recording of earthquake signals in the Ganga foredeep. The basement depth here is approximately 3000 m below the seismological observatory. The observatory is situated near the junction of north east rock sequence of the Himalayan orogenic belt and the area is covered with quaternary alluvial deposits of the Indo Gangetic plains and is about 25 km south of Himalayan Frontal Fault.
Northeast direction of crustal shortening is reported in the nearby areas. North of the Roorkee Seismological observatory lies the Ganga Tear, a conspicuous transverse fault along which nontectonic activity is evident.
The pier of the seismological vault was founded at a depth of 40 ft from the surface to minimize the cultural noise.
Consisted of short period vertical component L4C sensor and MEQ-800 recorder used for recording background noise sample data.
Consisted of broadband Triaxial sensor (Trilium) and Digital Recorder (Centaur) used for recording earthquake data in digital form.
