Software
Some special software is needed to perform our exercises.
Option 1: Use our preconfigured virtual machine
Download the following VM image and import it into VirtualBox.
- itc2023.ova - VM image with all software pre-installed (3.5 GB)
Choose Import Appliance from the File menu and select the downloaded VM
image. Then start the VM. The password is earthquake101 but it is configured
that you don't have to enter it.
In the guest system, open a terminal and type
itc-update
to get the exercise dataset and software hot-fixes.
Option 2: Use your own computer
Install the following software on your Linux or Mac machine (Windows may also work but is not recommended):
Presentations
- Source inversion in seismology
- The World of Seismological Data
- Pyrocko Squirrel
- Pyrocko Snuffler
- Pyrocko GF
- Grond - The practical side
Links
- Pyrocko web page
- Pyrocko manual

- Snuffler manual
- Squirrel command line tool tutorial
- Pyrocko GF overview
Do your own inversion:
-
find an event (M 5-6) in the Geofon catalog
-
find your crust2 velocity model:
from pyrocko import crust2x2
print(crust2x2.get_profile(lat=event_latitude, lon=event_longitude))
-
grond init example_regional_cmt my_first_grond_project -
cd my_first_grond_project -
mkdir gf_stores -
cd gf_stores -
download gf_store:
fomosto download crust2_j3 -
cd .. -
gedit bin/grondown--> change Line 1 pyrocko-python to python3 -
run grondown:
bin/grondown_regional.sh eventname
