Their seismic analysis seems to require a centrally mixed zone about 20% larger than what is expected from convection only.
They did not have access to seismic analyses, Kadak said.
During the last five years, seismic analysis has been transformed into a booming multibillion-dollar business.
In general, seismic analysis is based on the methods of structural dynamics .
Large bridges of this size were normally built straight, and California bridges required a detailed seismic analysis.
In addition, seismic analysis suggests that other areas may also be in danger.
The centers use supercomputers to tackle big scientific problems like ozone mapping, drug design and seismic analysis.
Procedures for multi-component seismic analysis were subsequently developed.
Many risks can be minimised with good earthquake construction, and seismic analysis.
The results may be in the form of a ground response spectrum for use in seismic analysis.
