WebNote:Peak ground acceleration values not in parentheses are for rock (Soil Profile Type B) and peak ground acceleration values in parentheses are for Soil Profile Type E. Figure B.12 Elastic Response Spectra Curves (5% Damping) for Soil Profile Type E (M = 8.0 ± 0.25) Title: WebValues are derived from peak ground acceleration and duration of the shaking, which are themselves influenced by factors such as distance to and depth of the hypocenter (focus), local soil conditions, and nature of the geology in between, as well as the event's magnitude; every quake thus entails numerous intensities. Web(a) Peak ground acceleration is 0.42 g of original time process; Maximum value = 1468.30 m/g 2 (time: 7 s). Sampling frequency = 50.00 Hz, (b) Peak ground acceleration reduced to 0.260 g of time process. Maximum value = 484.75 m/g 2 (time: 6.64 s). Sampling frequency = 50.00 Hz acceleration (m/s 2) (c) Response spectrum comparison. meeker health clinic
