Attempting to get a handle on this seemingly increase in volcanic activities is an interesting past time! First lets approach this by drawing a big circle. At OOOO top center of the circle Label Japan. Label each each earthquake/ volcanic event starting left, 350 degress west. Lets start putting each activity with a date, intensity, location. Earthquake With an E and volcano V. A list of each, location, intensity, and date. One thing I have picked up on is the progressive movement around the Pacific South and back to the East and now Northward. Secondly: The intensity has increased from reported 3.4...3.5....and we are now getting reports of 5.6....and some 6.+ February 15, 2012 Interestingly we might start with January 1, 2011, I didn't, just January 1, 2012 Some one with good record keeping skills might start this off. The rest of us can add notes on our watch sheets hence forth. Can we draw conclusions based on earthquake sites and progression site to site and to the activities of volcanos? Is there a direct relationship between earthquake and the increase of volcano activities. Are the volcano causing the increase in earthquakes. Is there some sort of relations between solar flares and Vulcanism activities? What else? Increase in earthquakes seldom felt before. Super Volcano quakes....Things like this put together by observation around the world would be an interesting observation for all of us.
