The earliest scientists first observed the waves that earthquakes produce before they could accurately describe the nature of earthquakes or their fundamental causes, as discussed in Lessons 1–5.

July 25, 1946, the United States detonated the first underwater nuclear bomb in history. The explosion on a test site of the Bikini Atoll generated a supersonic shock wave, crushing the hulls of ...

Earthquakes release waves of energy called seismic waves. They travel through the interior and near the surface of the Earth. P-waves, or primary waves, are the fastest moving type of wave and the ...

The study of earthquakes called Seismology, relies on the fact that different materials within the Earth react differently to stress. When a fault slips, energy radiates outward from the focus (the ...

When an earthquake strikes, it releases a massive amount of energy that travels through the Earth in the form of seismic waves. Read more about to understand how earthquakes occured and how we detect ...
