Determining strong-motion duration of earthquakes

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. WebThe strong-motion duration is found to be nearly proportional to the quantity Io/a 2max where a max is the maximum ground acceleration, and Io is the integral over time of the squared accelerations. A less important factor influencing the relationship between so and I o/a 2max is the predominant period To of the strong phase of the accelerogram. cincy grand prix https://jacobullrich.com
