Surveys(CGS) Seismic Hazards Zonation Project. There are not many Open
Source advocates here, but I am hoping to change that. I am mainly
involved in writing various programs that implements our Liquefaction(see 1) and
Earthquake Induced Landslide(see 2) Zones. These programs range from
simple data translators written in Perl to a program that calculates
liquefaction potential using borehole, ground water, and peak ground
acceleration using the Intergraph Modular GIS Environment
(MGE) programming language called MDL (a derivative of the C
Programming Language).</span></font><o:p></o:p></p>

font-family:Arial'>Since MGE is obsolete, we have been migrating to
Intergraph's Geomedia Professional and Geomedia Grid. These programs
have their strength (spatial queries, functional attributes, etc) and
weaknesses (problem importing/exporting shapefiles as well as Geotiffs,
coordinate system and projection are often messed up, inadequate grid
classifier, etc.) I know that FOSS GIS can do what we need to do and I'm
hoping that a California Chapter of OSGEO could be a great help.</span></font><o:p></o:p></p>

font-family:Arial'>(1) Liquefaction occurs when loose, water-saturated
sediments lose strength and fail during strong ground<br>
shaking. Liquefaction is defined as the transformation of granular material
from a solid state into a<br>
liquefied state as a consequence of increased pore-water pressure. The process
of zonation for liquefaction<br>
combines Quaternary geologic mapping, historical ground-water information and
subsurface geotechnical<br>
data. The liquefaction hazard Zone of Required Investigation boundaries are
based on the presence of<br>
shallow (< 40 feet depth) historic groundwater in uncompacted sands and
silts deposited during the last<br>
15,000 years and sufficiently strong levels of earthquake shaking expected during
the next 50 years.<o:p></o:p></span></font></p>

font-family:Arial'>(2)Landslides tend to occur in weak soil and rock on sloping
terrain. The Zone of Required Investigation for<br>
earthquake-induced landslides generally indicate areas characterized by steep
slopes composed of weak<br>
materials that may fail when shaken by an earthquake. The process for zonation
of earthquake-induced<br>
landslides incorporates expected levels of future earthquake shaking, evidence
of existing landslides, slope<br>
gradient and strength of hillslope materials.</span></font><o:p></o:p></p>
