Poster Abstracts
Preliminary results also suggest that kappa has a positive correlation with source-station distance as high frequency waves
become more attenuated with distance from source.
Further comparison of κ values between stations will highlight the influence of local geology on observed seismic records at
individual sites in the Bíobío region. As a result of the site response analysis, we highlight areas of the Bíobío region that may
be more susceptible to greater ground shaking following future large earthquakes.
VISUAL COMMUNICATION DESIGN FOR SHAKEOUT RESEARCH DISSEMINATION (A-008)
A. Nguyen
Preventing earthquakes from becoming disasters requires behavior change on the part of everyone at risk. This project seeks
to apply professional design to research dissemination and to information, education and communication (IEC) outreach
materials.
Risk RED, in cooperation with Earthquake Country Alliance, Western Washington University, and California State University,
Fullerton has developed a participant survey used in connection with annual community-wide ShakeOut drills worldwide.
This project focuses on communicating the results of these surveys by making the research findings understandable and
interesting, based on enhancing their visual appeal.
Deliverables are:
• Design of a full range of re-usable icons to highlight both research results and risk reduction concepts
• Development of Excel/Microsoft Word templates for a dozen infographics to convey research results in bar and
pie chart formats.
• Design for a re-usable Microsoft Word template for an annual research report.
Icons, infographics, charts, and templates were created with the intent of better visualization, maintaining a balance between
simple details and successful communicative imagery. The effort to support information with clear and appealing graphics is
expected to enhance research utilization as well as reinforcing disaster risk reduction education messages.
CFM V.4.0: CONTINUED UPGRADES AND IMPROVEMENTS TO THE SCEC COMMUNITY FAULT MODEL
AND ITS ASSOCIATED FAULT DATABASE (B-131)
C. Nicholson, A. Plesch, and J.H. Shaw
We are completing a major upgrade to the SCEC Community Fault Model (CFM v.4.0) which incorporates improvements in
3D fault representations, a detailed fault surface trace layer, and a new naming and numbering scheme for individual 3D fault
models that allows for closer links to the USGS/CGS Quaternary Fault database (Qfaults) and other SCEC data sets. Fault
representations in CFM are now referenced to the modern WG84 datum and the new surface layer in CFM allows 3D fault
models to be registered to the more detailed, mapped Qfaults and other digital fault maps. A systematic revision of CFM 3D
fault segments was triggered by unexpected discrepancies between some previous CFM fault representations and the newer
Qfaults surface traces, as well as by the availability of extensive catalogs of relocated earthquake hypocenters to better define
the subsurface geometry of active faults. New 3D fault representations for major fault zones, including the San Andreas from
San Gorgonio Pass to the Salton Sea, the subparallel Mecca Hills, the San Jacinto, the Elsinore-Laguna Salada (including El
Mayor-Cucapah), and the San Fernando/Sierra Madre fault systems are being added that allow for more non-planar, multistranded
3D fault geometry. These new revised 3D fault models and interpretations help characterize a more complex pattern
of fault interactions at depth between various fault sets and linked fault systems. In addition, a new SCEC fault database
hierarchical naming and numbering scheme is implemented that provides unique identifiers (number, name, abbreviation) for
each level of the fault hierarchy under which a particular fault segment is classified. Levels of fault hierarchy include Fault
Area, Fault Zone or System, Fault Section, Fault Name, Fault Strand or Model, and Fault Component, which can be easily
shortened to Fault System identifier and Fault Name (e.g., SJFZ-Clark fault). These additional fault hierarchical levels allow
for more flexible database searches and easier identification of fault components, alternative representations, and possible
system-level associations of individual 3D fault elements that comprise CFM. This hierarchical scheme also allows for
grouping related individual faults under a higher level fault system (e.g., Southern Frontal Fault System for the Raymond,
Hollywood, Santa Monica, and Malibu Coast faults) to help facilitate identification of potentially larger earthquake ruptures
between such kinematically linked fault segments.
