    The difference between an oscillatory and a trepidatory earthquake

    I THOUGHT YOU WOULD FIND THIS EXPLANATION VERY INTERESTING...



    Recently, California had a series of small earthquakes. Some were thought to be oscillatory, while others were believed to be trepidatory... It occurred to me that mostpeople might be confused about this, so I thought it wise to let you know the difference.






    The difference between an oscillatory and a trepidatory earthquake:

    1. This calculation is just for engineers:





























    2. And the following explanation is for laymen (non-engineers earthquake scientists):








    This is a trepidatory earthquake -- an upand down movement:
























    This is an oscillatory earthquake -- a side to side movement...






















    And this is a combination of both trepidatory and oscillatory:
















    Isn't science beautiful when properly explained?

    Good Thread Chris, but you forgot to mention the correlation between earthquakes and volcanic activity.

    Scientific explanation: Earthquake activity beneath a volcano almost always increases before an eruption because magma and volcanic gas must first force their way up through shallow underground fractures and passageways. When magma and volcanic gases or fluids move, they will either cause rocks to break or cracks to vibrate. When rocks break high-frequency earthquakes are triggered. However, when cracks vibrate either low-frequency earthquakes or a continuous shaking called volcanic tremor is triggered.

    Laymen's terms: Do not shake a carbonated beverage, if you don't want it to explode
