Skyquakes: Warnings From Earth's Destabilizing Core

Wednesday, January 18, 2012 8:11

Ominous booms thunder across the sky. These 'skyquakes' are abruptly erupting all over the world. Hundreds of thousands wonder in fear about the bizarre hums, explosive booms, and howling moans. From Russia, to Australia, from Chile to the Eastern Coast of the U.S., the sky is exploding. As the frequency and intensity increase people are asking: 'Is Doomsday approaching?' Some researchers fear that may be exactly what's coming...

Hyperborean vibrations from the Earth's destabilized core

AUDIO: Harmonics over Czech Republic - January 2012

NEW! Earth harmonics heard in Manitoba...animal reacts...eerie. Earth core mutation twisting subterranean rock. Keep eye on sky where you are for earth lights day or night.

ALERT: STRANGE 'SOUNDS' NOW BREAKING OUT ALL OVER THE WORLD!  NEWEST:

Eerie Sounds Over Nottingham, England

Strange Sounds Above London, England

Sounds Over Los Angeles, California

Harmonics may signal massive Earth core slippage

Millions of years ago the seas suddenly rose, islands disappeared, continents flooded, and mighty mountain ranges like the Andes rocketed from the depths of the ocean reaching many thousands of feet into the air within a matter of hours.

Seashells found in Andes, Earth's youngest mountains

Today fossils of bottom dwelling sea creatures-even actual parts of seashells-can still be found near the South American range's jagged mountain peaks.

Despite the fact that a few believe the Earth may flip on its axis, that's not very likely to happen.

Is the sky falling? No, the Earth's core is slipping...

What is happening is the liquid iron core of the Earth is spinning at a different rate than the planet's rotation and the slippage is causing a measurable migration of the Earth's magnetic field.

Earth's magnetic field in state of uncontrollable flux

The skyquakes are caused by harmonics deep inside the Earth traveling from a mutating core through the layers of the planet to the surface. The sky acts as a sounding board capturing and magnifying the sonic and electrical frequencies shot from the center of the world.

Life depends on Earth's core. Something's happening to it.

Death and destruction on an Apocalyptic scale

The stresses building up in the core deep in the heart of the world also migrate outwards to the mantel and eventually the crust. Slipping strata within the bowels of the planet create incredible pressures...pressures so great that temperatures soar and dense metals flow like liquids. [See Doomsday: Earth's core spinning out of control]

Water becomes a superheated plasma and interacts with layers of quartz crystals emitting harmonics audible as a hum and also generating earth lights and skyquakes echoing across the sky . [See: Underground lightning may cause earthquake and volcanic events]

Oceans can rise miles high in a matter of hours

The vibrations affect the crystals and can set in motion massive Earth changes culminating with continental upheavals, massive landslides, coastal areas collapsing, and ocean beds becoming mountain ranges.

Cities could become graveyards filled with deathtraps

Inside the Earth underground lightning's being transmitted planetwide.

Subterranean superstorms encircle the planet

Adding to the stress and fury are subterranean superstorms threatening to break out to the surface bringing with them death and destruction on an Apocalyptic scale.

Earth lights preceded great Fukushima quake of 2011

Those phenomena are exactly what is sometimes experienced shortly before mega-thrust earthquakes. Dazzling earth lights were seen in the sky before the Fukushima quake in Japan and reports as far back as the 1906 San Francisco earthquake recorded skyquakes preceding the destruction of that northern California city.

Cloud vortexes can form from core magnetic flux

Weird meteorological phenomena appear like Mammatus clouds

The global skyquakes might be an early warning of the major shift occuring deep beneath our feet-titanic, unstoppable forces that are paving the way towards planetwide cataclysms eclipsing those catastrophes described in the Byzantine legends of lost Atlantis.

Only a comparison Chaz but as I say it's hard to distinguish what is fact.
