What is the Ring of Fire?

The Ring of Fire is a horseshoe shape situated along the Pacific Ocean from New Zealand, along the eastern edge of Asia, north across the Aleutian Islands of Alaska, and south along the coast of North and South America.  The reason why the Ring of Fire is well known is because there are frequent earthquakes and volcanic eruptions that are situated within and along the Pacific Ocean.  It has been said that approximately 90% of the world's earthquakes and "two-thirds of the world's active volcanoes" (Teachers Guide to Stratovolcanoes of the World, 2004) occur along the 40,000 km Ring of Fire.

Psychology, Ring of Fire

When an individual experiences a trauma where it was unexpected and they were unprepared for it, a condition may arise for that individual called Post Traumatic Stress Disorder.  This disorder occurs in individuals who go through very traumatic events such as riots, war, the loss of a loved one and natural disasters.  The disorder is most commonly seen in soldiers in times of war where they experience many symptoms such as night terrors, panic attacks, emotional numbness, and loss of memory.  Generally, symptoms become noticeable at approximately 6 months after the trauma has occurred and can remain for a life time.  PTSD is a disorder that not only affects the one who has been exposed to the traumatic event, but to the individuals that surround them such as family and friends. 

 

Post Traumatic Stress Disorder is described as an alteration to an individual’s brain which changes the way the brain is structured and the way it functions.  The individual with PTSD is in constant fear of the re occurrence of the event and can re-live the event as if they were there again.  For an individual who has PTSD any reminder of the event such as a smell, noise, sound, or taste can trigger an event for a person where there begin to have panic attacks and this can be a danger to themselves.  Some symptoms for individuals become life altering where cases have been known where night terrors have become so dangerous in terms of the individual becoming violent not knowing what is going on and resulting in hurting themselves as well as their loved one.  They truly believe that they are back in time at the event and they re-live the event as if it were occurring right then.

 

The emotional trauma that the individual faces is extremely hard and painful to overcome the feelings and to live life again.  There are a number of ways that individuals can be helped to move past the traumatic event such as cognitive behavioural therapy.  Some studies that have been conducted have shown improvement with individuals with relaxation techniques as well as in some cases hypnosis (Jaffe, J., Segal, J., & Lisa Flores Dumke, L. F. 2007).
