Almost 500-percent increase between 1875 and 1993.

What Is the Scientific Explanation of These Earth Changes?

The primary cause for earthquake activity is energetic increases in the core. When these increases occur very rapidly, due to a sudden Solar emission, some of the luminous plasma in the core is compressed into a higher ZE density level by the intense surrounding pressures. Such a density shift allows the plasma to move freely through matter. This hyper-compressed plasma then bubbles up through the Earth’s mantle, and once the pressure is relieved, it displaces back down into the density of “physical matter.” A great explosive force is created as this intense heat is then released in a much cooler area, and this would certainly have an impact on geophysical activity, both for earthquakes and volcanoes.
