MFB (ModEM File Builder)

Overview

Simple GUI software to carry out pre- and post- procesess for ModEM (Egbert and Kelbert, 2012)

Features

• Simple GUI
• Pre- and post- processing can be done in one software.
• Initial model is created taking into account the topography.
• Observation point location and grid are automatically drawn.
• Observed and Calculated apparent resistivity and phase can be easily compared.
• Resistivity structure, hypocenters and other points can be easily exported to paraview format.
• Resistivity structure can be easily partially modified for sensitivity check.

Requirement

• python3 or more
• pandas
• numpy
• matplotlib
• seaborn
• pyevtk
• pyproj
• PysimpleGUI

Usage

1. Prepare DEM including header (lon, lat, height) and bathymetry (if needed) including header (lon, lat, depth).

2. Prepare the file (including header [lon lat] with the latitude and longitude of the observation point.

3. Find the EPSG code of the destination Cartesian coordinate system.(https://epsg.io/)

4. Launch MFB

   $ python mfb_gui.py

5. Configure settings via GUI (Push 'Save Settings' Button)

6. Make files (Push 'Make files' Button)

7. Carry out the inversion via ModEM

8. Carry out post-processes (The file about hypocenters must have header [lon lat depth m], m means magnitude. The file about points must have header [lon lat height].)

Installation

$ git clone https://github.com/r-tnk/MFB.git

Preparing files

DEM

• The DEM is not needed to be sorted.
• The DEM is needed to be separated from the bathemerty.
• A missing value of the DEM is filled by "-9999.00".
