GeoClaw Sample Code

Sample earthquake-generated tsunami based on the 2010 Chile event. Primarily to illustrate how set up topo and dtopo files.

See www.clawpack.org/users/topo.html for more information.

See maketopo.py [.html]. This downloads topography data from the GeoClaw topography database that originally came from the NOAA National Geophysical Data Center (NGDC) using Design-a-grid .

USGS site for earthquake data: earthquake.usgs.gov/earthquakes/eqinthenews/2010/us2010tfan

This example uses the final earthquake model from: Finite Fault model Click on "SUBFAULT MODEL" to find the data stored here in Chile2010_USGS.txt .

This is converted to Chile2010_USGS.tt3 by running maketopo.py [.html] or by "make topo". This uses an improved version of the Okada model, new in 4.6.3.

Two gauges are included at the locations of DART Buoy 32412 and 51406, see www.ndbc.noaa.gov/station_page.php?station=32412 and www.ndbc.noaa.gov/station_page.php?station=51406

To download other DART buoy data, see www.ndbc.noaa.gov/dart.shtml

See also the NOAA/PMEL Center for Tsunami Research site for this tsunami, containing DART data, tide gauges, MOST simulations: nctr.pmel.noaa.gov/chile20100227/

Plots of results

After running this code and creating plots via "make .plots", you should be able to view the plots in _plots/_PlotIndex.html .

The gauge data will be plotted along with de-tided observations from the DART buoys, stored in files 32412_notide.txt and 51406_notide.txt .

Fortran files

Makefile [.html]

Determines which version of fortran files are used when compiling the code with make and specifies where output and plots should be directed. Type "make .help" at the Unix prompt for options.

setprob.f [.html]

Standard for for GeoClaw

Python files

maketopo.py [.html]

Used to create topo file and dtopo data file.

setrun.py [.html]

This file contains a function that specifies what run-time parameters will be used.

setplot.py [.html]

This file contains a function that specifies what plots will be done and sets various plotting parameters.

Data files

The .data files are automatically generated using the information in setrun.py [.html].

Instructions

To make topo and dtopo data files:

  $ make topo

To make all data files, edit setrun.py and then

  $ make .data

To run code:

  $ make .output

To plot results, either generate html pages via:

  $ make .plots

All of this can be done with:

  $ source make_all.py
