چکیده

With advances in computational capabilities and refinement of seismic wavepropagation models in the past decade large three dimensional simulations of earthquake ground motion have become possible. The resulting datasets from these simulations are multivariate, temporal and multi-terabyte in size. Past visual representations of results from seismic studies have been largely confined to static two dimensional maps. New visual representations provide scientists with alternate ways of viewing and interacting with these results potentially leading to new and significant insight into the physical phenomena. Visualizations can also be used for pedagogic and general dissemination purposes. We present a workflow for visual representation of the data from a ground motion simulation of the great 1906 San Francisco earthquake. We have employed state of the art animation tools for visualization of the ground motions with a high degree of accuracy and visual realism.

Study of the 1906 San Francisco Earthquake

All quality teleseismic recordings of the great 1906 San Francisco earthquake archived in the 1908 Carnegie Report by the State Earthquake Investigation Commission were scanned and digitized. First order results were obtained by comparing complexity and amplitudes of teleseismic waveforms from the 1906 earthquake with well calibrated, similarly located, more recent earthquakes (1979 Coyote Lake...

The 1906 San Francisco earthquake: a centennial contemplation.

The publication of this issue of PrehospitalandDisasterMedicine coincides with the centennial of the 1906 Great San Francisco Earthquake. The 1906 San Francisco Earthquake does not rank with the larger earthquakes in world history and is not even the largest earthquake in US history. In fact, readers of this journal will recall many recent earthquakes that produced exponentially greater health ...

1 Appendix F Estimated Changes in State on San Francisco Bay Region

In the 70 years prior to the great 1906 San Francisco earthquake, seventeen M≥6 earthquakes shook the San Francisco Bay region; in the 94 years following there have been only five (Bakun, 1999). A plausible explanation is that after great earthquakes the crust in an entire region is relaxed, creating a "stress shadow" within which other large earthquakes are suppressed until plate tectonic stre...

Wavelet-based Analysis for Pulse Period of Earthquake Ground-motions

Pulse period of earthquake records has been known as a key parameter in seismology and earthquake engineering. This paper presents a detailed characterization of this parameter for a special class of earthquake records called pulse-like ground motions. This type of motions often resulting from directivity effects is characterized by a strong pulse in the velocity time history of motion, in norm...

TOPOLOGY OPTIMIZATION OF 2D BUILDING FRAMES UNDER ARTIFICIAL EARTHQUAKE GROUND MOTIONS USING POLYGONAL FINITE ELEMENT METHOD

In this article, topology optimization of two-dimensional (2D) building frames subjected to seismic loading is performed using the polygonal finite element method. Artificial ground motion accelerograms compatible with the design response spectrum of ASCE 7-16 are generated for the response history dynamic analysis needed in the optimization. The mean compliance of structure is minimized as a t...
