The Asian-Pacific plate known as “Ring of fire” because of regularity of earthquake and volcanic explosion. The geologists and scientists worked together and discovered two important equation which will determine the relation between strength of earthquake and volcanic explosion for next 50 years. They are x5 + x4 + x3 + x2 – 20x – 26 = 0 and x5 + x4 + x3 + 4x2 – 17x – 26 = 0 where x is relation coefficient of quake and volcanic explosion. Common roots are situation of worst case scenario.
