Performance
These traces record the 2002 Mw 7.9 earthquake on the Denali Fault in Alaska. Ground movements during this event approached 1 g in amplitude, making it the strongest ever recorded in the Alaskan interior.
The earthquake was recorded at two stations on the Trans-Alaska Oil Pipeline, each around 70 km distant. The pipeline is instrumented with CMG-5TD accelerometers, which combine 5T components with a built-in DM24 digitizer.
Using Güralp Systems' Scream! and ART software packages, the signal can be analysed in a variety of ways. The above graphs show the Fourier spectrum (left in each pair) and response spectrum measured at each of the two sites.
