Program
Scope
The long-period component of seismic ground motion generated by
earthquakes causes damage in near-fault regions
through source effects such as the directivity effect of rupture
propagation and the near-field term of body wave radiation.
In addition, the long-period ground motions attenuate slowly with
distance due to some path effects, and site effects amplify them in
distant basins, so that they can carry destruction to much greater
range.
Large-scale structures such as tall buildings and big tanks
can resonate with the long-period ground motions because their own
natural periods are in the same frequency band.
They can even be damaging in some circumstances; the worst example
with over 20,000 fatalities in Mexico City at a distance of 400 km
from the 1985 Michoacan earthquake.
A further example was provided by the 2003 Tokachi-oki earthquake in
Hokkaido, Japan. (Koketsu et al.,
Seism. Res. Lett., 76, No.1, 67-73, 2005)
Therefore, the simulation of long-period ground motion is one of the
most important parts of strong motion evaluation and prediction.
The modeling of velocity structures along propagation path and within
sedimentary basins also plays an important role.
We would discuss these aspects of the long-period ground motion in the
workshop.
Topics include numerical simulation, velocity structures, source
effect, path and site effects, damage and risk, and other related
issues on the long-period ground motion.
