Earthquake Data for Magnitude and Slip Scaling Relations

<p>Data files useful in earthquake scaling relations.&nbsp; They include compilations of a number of authors.</p> <p>Data files used in papers [Shaw, BSSA, 2013] and [Shaw, BSSA, 2023].&nbsp; The first set are .txt electronic supplements from [Shaw, 2013].&nbsp; The second set are a .csv file from [Shaw, 2023] and a&nbsp; .csv file from [Biasi, et al., 2013] used in that paper.&nbsp; Please use the references below if you use the data.</p> <p>-------------------------------------------</p> <p>[Shaw, 2013] files:</p> <p>Bruce E.

Some modifications of this dataset have been made, taking into account new LIDAR results of [Zielke <em>et al.,</em> 2010] of the 1857 M7.8 Fort Tejon event, and the addition of a new large 2008 M7.9 Wenchuan event [Xu <em>et al.,</em> 2009].</p> <p>Table S4, <strong>BSSA-D-11-00258-esupp_TableS4.txt</strong>, combines data from events common to Tables S2 and S3, to enable a comparison of events in common.</p> <p>References</p> <p>Ellsworth, W.

Shaw,<br> ` Magnitude and Slip Scaling Relations for Fault Based Seismic Hazard&#39;,<br> <em>Bulletin of the Seismological Society of America</em>,&nbsp; 2023.</p> <p><strong>catalogMeanGlobal.csv</strong>:&nbsp;&nbsp; An effort to compile a database from the existing literature of finite source information on recent large and great earthquakes was recently led by a New Zealand group as part of an update to their national seismic hazard model [Stirling, et al., 2022].&nbsp; They looked globally at M&gt;7.5 shallow earthquakes since 1990, along with an additional subset of the M&gt;7.0 shallow events since 1990 which were less poorly constrained.&nbsp; These events were compiled through an extensive literature review.<br> [Shaw, 2023] took that database and used averages over the width, length, area, magnitudes, and dips from the different sources in the literature for the same events to obtain a finite source data set for each event to analyze further. One issue with this dataset is that the complied data used for the averages did not undergo a thorough review, so there may be potential outliers and problems in individual data points.&nbsp; In aggregate, statistically, it can be useful, which is how it was used.&nbsp; But caution for any individual data point is warranted.&nbsp; It is presented as a useful starting point for further development,&nbsp; It is not a thoroughly vetted or definitive dataset.</p> <p><strong>AppendixR1_TableR2_Biasi_adapted.csv </strong>is adapted from a file compiled and published by [Biasi, et al, 2013].&nbsp; It contains slip, length, magnitude, and other data for large crustal earthquakes.</p> <p>References</p> <p>Biasi, G.
