The Ring of Fire Debunked

I would say these are trenches that previously serve as valleys congruent with the theory of Polar Shifts that tell us that deserts are dried-up oceans. 

Let us imagine that these valleys are the base of the structures known as mountain ranges. The height, width and breadth and the composition of the structures defines their strength to withstand earthquakes. Flexible and wide structures are ideal. Shaky is okay as long as the structure dances with the quake not go against it.

"In 1970, Soviet scientists started drilling the Kola Superdeep Borehole in Murmansk, Russia. They wanted to learn about Earth's crust, and they wanted to beat American scientists who had abandoned their Project Mohole in 1966.

After 24 years of digging, and several branches in the hole, the deepest branch of the Kola Superdeep Borehole stopped in 1994 at 12,262 meters (about 7.5 miles). It's only nine inches in diameter at the bottom. It is still the deepest hole in the world, and the process of drilling was incredibly difficult. (For reference, the Mariana Trench is approximately 10,994 meters deep at The Challenger Deep—and it's not a drilled hole.)

Interestingly, Kola is not the longest hole; in May 2008, an oil well earned that record, though it's nowhere near as far underground.

So what did scientists find at the bottom of the hole? First, there's lots of water down there—though it may be formed from stray oxygen and hydrogen atoms squeezed out of rock minerals. Second, there are plankton fossils as deep as 6700 meters. Third, it's incredibly hot—more than 350 °F. For all the effort and decades of work, this hole only went 0.2% of the way to the center of the Earth!"

Imagine 7.5 miles excavated deep into the earth is only 0.20 percent of the Earth. Thus scientists imagine what is the composition of the Earth's mantle, Outer Core and Inner Core. My guess is that chemical reactions beneath the Earth is causing quakes. They produce freon that freezes minerals so they expand. When minerals expand they cause the quakes. Gases can also be produced underground. Methane deposits are abundant but when they are lit up it causes explosions.
