MN

The MN plugin is designed to compute the Canadian Nuttli magnitude according to the Geological Survey of Canada.

Description

The amplitude unit in SeisComP is meter/second (m/s).

Settings

Add the nuttli plugin to the list of loaded plugins and set the region-specific calibration parameters in the global configuration. E.g. in the global module configuration:

plugins = ${plugins},nuttli

Amplitude time window parameters and magnitude corrections are configurable in the global bindings.

scamp

Add the Nuttli magnitude type to the range of magnitudes for which the amplitudes are to be calculated, e.g.:

amplitudes = ML,MLv,mb,mB,AMN

Note

Provide AMN for computing Nuttli-type amplitudes.

scmag

Add the Nuttli magnitude type to the range of magnitudes to be calculated, e.g.:

magnitudes = ML,MLv,mb,mB,MN

Configuration

amplitudes.MN.velocityModel

Type: string

The travel time table set compiled for LocSAT. The tables are located in "share/locsat/tables/[vmodel].*". Default is iasp91.

magnitudes.MN.region

Type: path

The path to the BNA file which defines the valid region for the MN magnitude. Note that the entire path from source to receiver must lie entirely within the polygon(s). Default is @DATADIR@/magnitudes/MN/MN.bna.
