This bug affects the amplitudes of small events in particular, so you may wish to review some of your smaller recent events to see the extent of the differences.</div><div class=""><br class=""></div><div class="">This fix is highly recommended (essentially, it’s mandatory if you are using BA08). The fixed code is version 1618 in the repository, but only requires changing one line in BA08.pm, so you may wish to make this change in your source (don’t forget to “make” afterwards to propagate the fix from the src/lib/GMPE directory to the perl/lib directory).</div><div class=""><br class=""></div><div class="">The change to BA08.pm is at line 654:</div><div class=""><blockquote style="margin: 0px 0px 0px 40px; border: none; padding: 0px;" class=""><div class=""><br class=""></div><div class="">< .
