The Ring of Fire in Earth Sciences is already well defined. Looking at floods and earthquakes, I just noticed that the area is a whole considering natural bad events. The imaginary circle and the imaginary red lines are drawn by myself by having the circle center as Hawaii island, the land in the middle of the Pacific Ocean. I kept the length of imaginary red line, not changed, on this map. The epicenter of an Earthquake is not the place that death occurred most, but the seismic activity is highest, most of the times to find exact place of the quake is not easy. To draw imaginary circles, to find the epicenter is important. I will check again if the places I pointed on the below map are exactly the epicenters of early 2016 year earthquakes.
In future better computer programs will draw better imaginary lines etc.
A foreshock is an earthquake that occurs before
a larger seismic event, around Pacific Ocean Ring of Fire, some seismic events might be a sign for following future event. Earthquake history should be studied to correlate quakes. Old history is not easy to study, sometimes natural disasters occur during wars, people misjudges that event is human made, not disaster. Think that while in a war an explosion occurred from earth volcanic or something similar, how one will tell that it is not war enemy but from earth itself. Earthquakes are not always just shaking, sometimes weird things happen, the soil jumps upwards etc. Natural event experts are not available when needed, big disasters even kill the people who could interpret what is going on.
In very old days, prior to Science developed, human interpreted many deaths as war, bombing from enemies, today fortunately we explain events as natural disasters etc.
Another point is that Floods might not results from only rain, but under the soil things happen while it rains.
