What is a normal amount of activity for the Ring of Fire? Well, during the entire 20th century there were 3,542 volcanic eruptions, or 35 per year. So, we are well above what an entire calendar year should be.
And of course we are witnessing a tremendous amount of earthquake activity as well. Nepal was just hit by the worst earthquake that it had seen in 80 years, and scientists are telling us that the Himalayas actually droppedby an astounding 3 feet as a result of that one earthquake. How much more does our planet have to shake before people start paying attention?
Of course the things that we have been seeing lately are part of a much larger long-term trend. Seismic activity appears to have been getting stronger over the past few decades, and now things really seem to be accelerating. The following is how one news sourcerecently summarized what we have been witnessing…
If it seems like earthquakes and erupting volcanoes are happening more frequently, that’s because they are. Looking at global magnitude six (M6) or greater from 1980 to 1989 there was an average of 108.5 earthquakes per year, from 2000 to 2009 the planet averaged 160.9 earthquakes per year: that is a 38.9% increase of M6+ earthquakes in recent years. Unrest also seems to be growing among the world’s super-volcanoes. Iceland (which is home to some of the most dangerous volcanoes on the planet), Santorini in Greece, Uturuncu in Bolivia, the Yellowstone and Long Valley calderas in the U.S., Laguna del Maule in Chile, Italy’s Campi Flegrei – almost all of the world’s active super-volcanic systems are now exhibiting some signs of inflation, an early indication that pressure is building in these volcanic systems.
But, the Ring of Fire isn't the only seismic threat the U.S. is facing right now. The New Madrid Fault line is also waking up, and one sizeable seismic activity could trigger the same in the other fault. See video next page.
