Earthquake design spectra Given a earthquake ground acceleration, there is no difficulty to compute response using Newmark’s method as the previous example. Therefore, we can generate a response spectrum for that earthquake. We are interested in the maximum relative displacement, velocity, and total accelerations. how to make gray hair shinier

The rupture displacement in an earthquake is typically about 1/20,000 of the rupture length. For example, a 1 km long rupture from an Mw 4.0 event has a displacement of about 1km/20,000, or 0.05 metres. A magnitude Mw 8.0 earthquake with a rupture length of 100 km may give a displacement of a few metres. how to make gray hair lighter
