5203 |a“The two magnitude 6 earthquakes on May 1, 2017 were felt in the regions of Haines Junction and Whitehorse, YT and minor damage was reported. Five-percent damped spectral accelerations calculated from a seismograph situated near Haines Junction suggest that the first event had stronger ground motions than the second, even though the second had the larger magnitude. In Haines Junction, spectral accelerations reached approximately 1 % to 7.5 % of the 2015 seismic hazard design values (e.g. 3 % at 0.2 s). While the seismograph in Whitehorse was not operational at the time, the predicted motions from the event reached 5 % to 22 % of the design values (e.g. 12 % at 0.2 s for the first event). The higher percentages are largely due to the lower seismic hazard design values for Whitehorse. The results in this work are given for firm ground conditions (site class C), and varying local conditions could amplify or reduce these values”--Abstract, p. 4.
