Although Earth’s surface looks continuous and uniforme, in reality is fulfilled with slips and faults all around. Pangea theory states that millions of years ago, our planet had a huge continent floating over the oceans, this huge extension of land was called Pangea and included all continents that now exist. 

Several millions of years ago, Pangea fragmented and huge tectonic plates began to move away from each other or converge toward one another. Also, oceanic plates move underneath land plates which makes of each converging zone or separating zone unique. It’s a geophysical objective to research every single piece of tectonic plates for the variety of conditions and facts surrounding it. Neverthless, we can now know that land tectonic plates and oceanic plates are different in essence. Oceanic plates are denser and therefore submerge lighter land plates. 

When, however two plates are of the same origin (two oceanic or two land) because they are of similar density, instead of one subducting underneath the other, they usually move along each other. This creates a fault. Faults are zone of rugosity on tectonic plates that are sliding in relationship to the other. Faults are commonly zone of earthquake increased activity. There’s three major types of faults:

  • normal fault 
  • reverse fault 
  • strike slip fault 

Then, there’s many subtypes of faults for these three major faults types. There’s many locations around the world where increased sysmic activity is associated with sets of faults. Faults can be located underneath the sea or over land. Researching faults can allow geoscientists to predict sysmic activity and sysmic probability in specific locations. Read more soon…
