<p class=MsoPlainText>Methods of Mmax Estimation East of the Rocky Mountains <o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>The magnitude of the largest earthquake that is thought
possible within a specified area (Mmax) is an important value in probabilistic
seismic-hazard assessment. East of the Rockies, outside the New Madrid seismic
zone and a few others, seismicity is generally sparse and large earthquakes are
rare.<o:p></o:p></p>
<p class=MsoPlainText>In such areas Mmax must be estimated indirectly. The
report discusses pros and cons of the various methods that have been used or
suggested over the years to estimate Mmax in various parts of the East. The
report was part of the preparatory reading for attendees at a workshop on
eastern Mmax that was held in Golden, Colorado on September 8-9, 2008. The 1 MB
report is available free at <a href="http://pubs.usgs.gov/of/2009/1018/">http://pubs.usgs.gov/of/2009/1018/</a>.<o:p></o:p></p>
