WASHINGTON : In Jules Verne's classic 1864 novel"Journey to the Center of the Earth," adventurers descend through an Icelandic volcano into a vast underground world populated by prehistoric creatures as they explore our planet's interior. The actual center of the Earth is nothing like this fanciful depiction - and in some ways is even more dramatic.
Scientists in 2002 proposed that lurking within this inner core was an innermost section separate from the rest, akin to a Russian Matryoshka nesting doll. The increasing sophistication of seismic monitoring enabled this to be confirmed. "We analyzed digital records of ground motion, known as seismograms, from large earthquakes in the last decade. Our study becomes possible thanks to the unprecedented expansion of the global seismic networks, particularly the dense networks in the contiguous U.S., the Alaskan peninsula and over the European Alps," Pham added.
"If we were somehow able to dismantle the Earth by removing its mantle and the liquid outer core, the inner core would appear shining like a star. Its temperature is estimated to be about 5,500-6,000 degrees , similar to the sun's surface temperature," Tkalčić said.
