Theme
IV-1: Issues in Geo-Spatial Data for Major Natural Disasters
– Dr. A. Kiremidjian (US) and Dr. F. Sabetta (Italy)
Presentation abstracts
will appear here as soon as possible.
Data required in seismic
hazard analysis are varied and come in different forms and quality.
Such data include earthquake event occurrence, local soil, geological
and ground motion recordings. These data are necessarily spatially
distributed requiring the use of two- or three- dimensional geographic
information systems and other visualization tools. Considerable
difficulty exist in generating databases that are homogeneous
in time and space, or can be reduced to formats that can be used
in seismic hazard model parameter estimation. Similarly, the outputs
of seismic hazard analysis are often geospatially distributed
data that require geographic information systems and database
management systems for storage and display.
In the session papers
will be presented that address issues of acquiring, handling and
integrating seismological and geological data that need to be
resolved in generating databases for seismic hazard analysis.
In addition, methods for displaying the original geospatial data
as well as outputs from seismic hazard analysis also pose a challenge
and solutions used to date can be very informative. The session
will have five to six papers focusing on issues of data homogeneity
in time and space, uncertainty in spatial distribution, simple
as well advanced techniques of data overlays and integration,
extraction of three dimensional information from two dimensional
data, and the generation of seismic hazard information useful
to wide audiences.
