Strong Ground Motion Estimation [PDF]
, 2012 This progressive sequence of ground motion surprises suggests that the current state ofknowledge in strong motion seismology is probably not adequate to make unequivocal strong ground motion predictions. However, with these caveats in mind, strong ground motion estimation provides substantial value by reducing risks associated with earthquakes and ...

Simulation of strong ground motions [PDF]
Bulletin of the Seismological Society of America, 1980 abstractThe estimation of potential strong ground motions at short epicentral distances (Δ = 10 to 25 km) resulting from large earthquakes, M ≧ 6.5, generally requires extrapolation of a limited data set. The goal of this project has been to quantify the extrapolation through a simulation technique that relies heavily upon the more extensive data set ...

Chile Strong Ground Motion Flatfile
Earthquake Spectra, 2016 The Nazca-South American plate boundary produces large-magnitude events (Mw > 8) every 20 years on the coast of Chile. This work describes a public ground motion database that contains 3,572 records from 477 earthquakes and 181 seismic stations, which includes the recent 2015 Mw 8.3 Illapel earthquake.

Properties of strong ground motion earthquakes* [PDF]
Bulletin of the Seismological Society of America, 1955 Summary The analysis given here considers that an earthquake fault is formed by the superposition of a large number of incremental shear dislocations the sudden release of which produces the earthquake. It is postulated that during an earthquake the incremental dislocations are released in such a way that the average slip is proportional

Investigating Possible Regional Dependence in Strong Ground Motions [PDF]
, 2010 It is common practice to use ground-motion models, often developed by regression on recorded accelerograms, to predict the expected earthquake ground motions at sites of interest. An important consideration when selecting these models is the possible dependence of ground motions on geographical region, i.e., are median ground motions in the (target ...

A decomposition of strong ground motion
Bulletin of the New Zealand Society for Earthquake Engineering, 1994 The Cedar Hills Nursery strong motion record of the 1987 October 1st Whittier Narrows earthquake can be decomposed into five physically distinct components. These are the usual radial, circumferential and vertical components, plus a 2.84 Hz resonance along 317° N and a 3.27 Hz resonance along 317° N.
