Articles general

• Aftershock - "An aftershock is a smaller earthquake that occurs after a previous large earthquake, in the same area of the main shock." - Wikipedia
  
• Earthquake - "An earthquake (also known as a quake, tremor or temblor) is the result of a sudden release of energy in the Earth's crust that creates seismic waves." - Wikipedia
• Fault (geology) - "In geology, a fault is a planar fracture or discontinuity in a volume of rock, across which there has been significant displacement. Large faults within the Earth's crust result from the action of tectonic forces. Energy release associated with rapid movement on active faults is the cause of most earthquakes..." - Wikipedia
• Lists of earthquakes - Wikipedia
  
• Seismology - "Seismology is the scientific study of earthquakes and the propagation of elastic waves through the Earth or through other planet-like bodies. The field also includes studies of earthquake effects, such as tsunamis as well as diverse seismic sources such as volcanic, tectonic, oceanic, atmospheric, and artificial processes (such as explosions)." - Wikipedia
