Updated: Mystery Booms and Inner Earth Core Changes?

“An Earth's 'inner-inner core,' about half the diameter of the whole inner core, has been found to have iron crystals ... aligned differently, that behave differently from their counterparts in the outer-inner core. That means the Earth's inner-inner core could be made of a different type of crystal.”

“The Earth at depth is a very mysterious place.
When the geophysicist is saying it (infrasound frequency)
goes from the core, transmits through the mantle to the crust,
is able to exit that, get all the way up to the ionosphere and perhaps
get reflected back down - if these frequencies are
very low ... there could be something to this.”

Updated February 10, 2015 / June 28, 2013 Jamestown, North Dakota, and Palo Alto, California - The February 9, 2012, journal Nature Geoscience, reported a new research discovery of a small "inner-inner core" inside the Earth's whole inner core that is inside the Earth's outer core that is inside the Earth's mantle and all covered by the Earth's crust was published by T. Wang, X. Song and H. Xia, University of Illinois and Nanjing University, China. See NG link in Websites below.
