Separate Earthquake Signals from Nuclear Explosions

Basic Information:

In this project, I develop machine learning models to seperate earthquake signals from nuclear explosions. Both earthquakes and nuclear explosions generate seismic waves that can be detected thousands of kilometers away. However, it is not always an easy task to separate them from each other. Although seismologists have developed methods, it is sometimes very challenging. For example, a recent 3.4 magnitude quake from North Korea was interpreted as 'suspected explosion' but later identified as natural. More details can be found here : http://www.independent.ie/world-news/asia-pacific/small-north-korea-earthquake-likely-natural-not-caused-by-nuclear-test-say-experts-36161584.html

The primary objective is to develop machine learning models to separate natural earthquakes from nuclear explosions.
