Nuttli magnitude for Canada and other Cratonic regions
|
|
|
|
Description
|
|
===========
|
|
|
|
MN is the Nuttli magnitude :cite:p:`nuttli-1973` for Canada and other Cratonic
|
|
regions. It is implemented by the *nuttli* plugin according to the
|
|
Geological Survey of Canada (NRCan).
|
|
|
|
For measuring AMN amplitudes and for computing MN magnitudes |scname| provides
|
|
regionalization.
|
|
|
|
|
|
Amplitude
|
|
---------
|
|
|
|
Amplitude unit in |scname|: **meter/second** (m/s)
|
|
|
|
|
|
Settings
|
|
========
|
|
|
|
Add the *nuttli* plugin to the list of loaded plugins e.g. in the global module configuration:
|
|
|
|
.. code-block:: sh
|
|
|
|
plugins = ${plugins},nuttli
|
|
|
|
Adjust MN-specific global bindings parameters in the amplitude section and set the
|
|
region-specific calibration parameters in the global module configuration.
|
|
|
|
|
|
scamp
|
|
-----
|
|
|
|
Add the Nuttli amplitude type, **AMN**, to the range of magnitudes for which the amplitudes are
|
|
to be calculated by :ref:`scamp`, e.g.:
|
|
|
|
.. code-block:: sh
|
|
|
|
amplitudes = AMN
|
|
|
|
Adjust MN-specific global bindings parameters in the amplitude section and set the
|
|
region-specific calibration parameters in the global module configuration
|
|
(amplitude section).
|
|
|
|
.. note::
|
|
|
|
Provide *AMN* for computing Nuttli-type amplitudes.
|
|
|
|
|
|
scmag
|
|
-----
|
|
|
|
Add the Nuttli magnitude type, **MN**, to the range of magnitudes to be calculated by
|
|
:ref:`scmag`, e.g.:
|
|
|
|
.. code-block:: sh
|
|
|
|
magnitudes = MN
|
|
|
|
Adjust MN-specific global bindings parameters in the magnitude section and define
|
|
the region polygons in the global module configuration (magnitude section).
