<p class=MsoNormal style='text-align:justify'> The
Conference concerns the most recent research and the various methods to develop
and use intraplate earthquake time histories, particularly in the <ns2:place>Central
U.S.</ns2:place> The conference hopes to bring together researchers,
design practitioners, government-agency specialists, and large
facilities’ design managers to raise the state of practice. Contributed
posters or presentations are encouraged. Acceptable topics include
Central US Time History assessment or use, and Time Histories calculated
for particular <ns2:place>Central US</ns2:place> sites. The meeting
schedule will be adjusted for contributed presentations and posters. <o:p></o:p></p>
<p class=MsoNormal style='text-align:justify;text-indent:.5in'>The objective of
the conference is to raise the state of practice and extend the confident use
of time histories. Noted researchers (as invited speakers) and those who
create and/or use time histories (as presenters) will discuss elements and
methodologies for determining and using time histories. The conference
will also be concerned with the precision and accuracy of the methodologies and
what added information would lead to the greatest reduction in
uncertainty. Authors are encouraged to present time histories for
different <ns2:place>Central U.S.</ns2:place> regional locations or
cities. A compact disc may be created of the proceedings. <o:p></o:p></p>
<p class=MsoNormal style='text-align:justify'> Intraplate
earthquake time histories are a controversial topic, particularly compared to
western <ns2:place><ns2:country-region>U.S.</ns2:country-region></ns2:place>
evaluations (a plate margin with many more applicable events and
recordings). New Madrid Seismic Zone’s and other sources’
intraplate seismicity, attenuation, spectra, and local site conditions pose
difficult issues concerning unique Central U.S. properties, methodologies, and
their accuracies. This is an extremely important topic as the
Bicentennial approaches for the Great New Madrid Series of earthquakes in 1811
and 1812. U.S. Geological Survey (USGS) and the <ns2:place><ns2:PlaceType>University</ns2:PlaceType>
of <ns2:PlaceName>Memphis</ns2:PlaceName></ns2:place>’ Center for
Earthquake Research and Information (CERI) are strongly supporting the
conference. <o:p></o:p></p>
<p class=MsoNormal style='text-align:justify;text-indent:.5in'>Several
different practice areas play important roles in the development of time
histories. These areas range from local site investigations and hazard
studies to regional studies of paleoliquefaction, faulting, tectonic movement
and stress fields, velocity models and areas of engineering seismology. The
design community depends upon proper time histories. The noted intraplate
time-history issues impact the built environment of (nuclear, traditional, and
advanced design) power plants, transportation and utility infrastructure, and
business development and continuity. There are also the broader
implications for world-wide intraplate regions. <o:p></o:p></p>
<p class=MsoNormal style='text-align:justify'> The
key presenters are: <b>Gail Atkinson</b> (<span style='color:black'>University
of Western Ontario</span>), <span style='color:black'>Characteristics of ground
motions in inactive regions and associated constraints on time history methods;
<strong>Martitia Tuttle</strong><strong><span style='font-weight:normal'>
(USGS, Memphis, TN)</span></strong><b>,</b> </span>Geological Record
of Ancient Earthquakes in the Central US<span style='color:black'>; </span><b>Rob Williams</b>
(USGS, Golden, CO), <span style='color:black'>Shear-wave velocity
structure in the Central US</span>; <b>Dominic Assimaki</b> (Georgia
Tech), Nonlinear site response in ground motion predictions; <b>Jack Baker</b>
(Stanford University), Active Region Time History Selection/Generation
Approaches; <b>Chris Cramer</b> (CERI, University of Memphis), Central
& Eastern US Time History Selection/Generation Approaches; and, <b>Reginald DesRoches</b>
(Georgia Tech), Engineering Applications and Issues for the Central US. <o:p></o:p></p>
<p class=MsoNormal style='text-align:justify'> Please
make your plans to attend and to provide an abstract for a poster or
presentation. Abstracts for presentations or posters are invited by May
11, 2009. The cost of the Shlemon Specialty Conference and the hotel are
very reasonable for attendees relative to other meetings. <o:p></o:p></p>
<p class=MsoNormal style='text-align:justify;text-indent:.5in'>Registration,
abstract submission and preliminary program information are available at <b><span
