About the course
By the end of the course, you’ll know the basics of seismology and how to use the technical instruments and programs in practice. So it doesn't matter what level you’re on. Complex things are explained with simple and accessible language.
Geophysists, mathematicians, geologists, geochemists, petrologists, engineers and everyone interested will find a lot of new information and get the access to the author's research methods and scientific algorithms that are used by seismologists all over the world.

Course program
Module 1. Tomography as a tool to look inside the Earth
  • What is this course about?
  • What can we see inside a little stone?
  • Doing tomography with a hammer and explosions
  • Earthquakes show us the Earth deep inside
  • How did people learn to measure earthquakes?
  • First attempts to look deep into the Earth
  • Body waves. How do they propagate inside the Earth?
  • Surface waves
Module 2. Look inside a volcano
  • Land of Fire — Kamchatka
  • Installing seismic stations on volcanoes. Almost a Hollywood adventure
  • KISS of the Kamchatkan volcanoes
  • Tomogram a few days before a volcano explosion (case of Bezymianny volcano in Kamchatka)
  • Huge steam boiler within Gorely volcano
  • Three independent views on the magma system of Avacha volcano
Module 3. Tomography: the must-know things
  • Too many unknowns, too little information: is the problem unsolvable?
  • Simplify – linearize – discretize
  • Miraculous inversion: solving millions of equations on a simple PC
  • Start working with Basic Tomo
  • BASIC TOMO. Recover the smiling face
  • Playing tomography chess
  • Ray tracing: shoot or bend?
  • PROFIT code: basic principles
  • PROFIT code: start working with data
  • PROFIT code: process our experimental data
  • Go to the field with a big hammer to make a real seismic experiment
Module 4. Doing tomography with natural sources
  • Earthquakes: trouble for people, but precise tool for scientists to study the Earth. Mechanism - rock fracture
  • How to localize earthquakes?
  • LOTOS: tool to explore 3D structures and localize earthquakes
  • LOTOS: Basic principles
  • LOTOS: look inside a supervolcano
  • LOTOS: look at Stromboli
  • Noise is another seismic source
  • Surface wave tomography: two-step workflow
  • Problem of testing: how far our images from the absolute truth?
  • Concluding video: What’s next?
