Web[1] We measure ground motion around the Lake Mead, Nevada, using synthetic aperture radar interferometry. The lake water level has fluctuated through time since impoundment in 1935. To quantify the deformation due to water level variations over the past decade, and to constrain the crust and mantle rheological parameters in the lake area, we analyze 241 … WebTo determine the effect of strong motion duration on structural response, ground motion sets of varying durations are used in this study through nonlinear time history analyses. These ground motion sets include both "long" duration records and “standard” records used to benchmark any change in structural response. 2.1 Benchmark Record Sets WebDec 28, 2024 · The distance after which the duration of ground motions for small magnitude events saturate is ∼60 km for shallow crustal earthquakes and ∼200 km for subduction earthquakes. Another difference between shallow crustal earthquakes and subduction earthquakes is the slope of duration versus distance. michigan\u0027s cereal city
