<h2>Description<a class="headerlink" href="#description" title="Permalink to this heading">¶</a></h2>
|
||
<p>MLc is a custom magnitude for local events based on <a class="reference internal" href="global_ml.html#global-ml"><span class="std std-ref">ML</span></a> but
|
||
with greater flexibility.
|
||
The original implementation is based on specifications by the Hessian Agency for
|
||
Nature Conservation, Environment and Geology, Hessian Earthquake Service.
|
||
More options have been added allowing the magnitude to be configured with
|
||
great flexibility in order to account for many different conditions. The
|
||
general procedures for measuring amplitudes and computing magnitudes are
|
||
outlined in the <a class="reference internal" href="../base/concepts/magnitudes.html#concepts-magnitudes"><span class="std std-ref">“Concepts” section on magnitudes</span></a>.</p>
|
||
<p>The MLc magnitude is very similar to the original <a class="reference internal" href="global_ml.html#global-ml"><span class="std std-ref">ML</span></a>,
|
||
except that</p>
|
||
<ul class="simple">
|
||
<li><p>Amplitude pre-filtering is applied by default.</p></li>
|
||
<li><p>Wood-Anderson simulation is optionally applied and can be deactivated.</p></li>
|
||
<li><p>Measured amplitudes can be scaled accounting for expected units.</p></li>
|
||
<li><p>Measured amplitudes are combined by taking the maximum instead of the average.</p></li>
|
||
<li><p>A parametric <a class="reference internal" href="#mlc-station-magnitude"><span class="std std-ref">magnitude calibration</span></a> function
|
||
applies but a correction in the form log10(A0) can be configured for converting
|
||
measured amplitudes to station magnitudes.</p></li>
|
||
<li><p>Hypocentral instead of epicentral distance is considered by default.</p></li>

<h3>Amplitudes<a class="headerlink" href="#amplitudes" title="Permalink to this heading">¶</a></h3>
|

<p>Some general conditions apply for measuring amplitudes:</p>

<ul class="simple">

<li><p>Components used for amplitude measurements: both horizontal components

<h3>Network magnitude<a class="headerlink" href="#network-magnitude" title="Permalink to this heading">¶</a></h3>

<p>The network magnitude is computed from station magnitudes automatically by

Originally the median was computed from all station MLc to form the

<a class="reference internal" href="../base/glossary.html#term-network-magnitude"><span class="xref std std-term">network magnitude</span></a> MLc. Here, the trimmed mean is applied. Outliers
|

beyond the outer 12.5% percentiles are removed before forming the mean. The

method can be adjusted in <a class="reference internal" href="scmag.html#scmag"><span class="std std-ref">scmag</span></a> by <a class="reference internal" href="scmag.html#confval-magnitudes.average"><code class="xref std std-confval docutils literal notranslate"><span class="pre">magnitudes.average</span></code></a>.</p>
