This weekend, North Korea conducted their most powerful nuclear test ever, with what was believed to be a hydrogen bomb in the northern part of their country. The explosion was so massive that it triggered a man-made earthquake measuring 6.3 on the Richter scale. If North Korean sources are to be believed, the bomb tested was a powerful 100 kiloton weapon.
But that's not all. To take the massive threat to an entirely different level, the North Korean state news also warned that a powerful hydrogen bomb could be detonated at a high altitude to create an electromagnetic pulse (EMP) capable of taking out parts of the American power grid. (PS: They have two satellites orbiting over the United States that could potentially carry out such an attack.)
Knowledge is power, so let's break down this information with some explanations.

What is a hydrogen bomb?
A hydrogen bomb has some similarities to an atom bomb, but works using an opposite chemical reaction and is far more powerful. Both hydrogen bombs and atomic bombs are nuclear in nature, so after the initial blast, there would be deadly radioactive fallout and environmental issues.
An atom bomb is what was used by the United States against the Hiroshima and Nagasaki, Japan during World War 2.
