VOLCANO SCREAM PRECEDES ERUPTION

KING JESUS IS COMING FOR US ANY TIME NOW. THE RAPTURE. BE PREPARED TO GO.

PSALMS 98:1-
 1  A Psalm. O sing unto the LORD a new song; for he hath done marvellous things: his right hand, and his holy arm, hath gotten him the victory.
2  The LORD hath made known his salvation: his righteousness hath he openly shewed in the sight of the heathen.
3  He hath remembered his mercy and his truth toward the house of Israel: all the ends of the earth have seen the salvation of our God.
4  Make a joyful noise unto the LORD, all the earth: make a loud noise, and rejoice, and sing praise.
5  Sing unto the LORD with the harp; with the harp, and the voice of a psalm.
6  With trumpets and sound of cornet make a joyful noise before the LORD, the King.
7  Let the sea roar, and the fulness thereof; the world, and they that dwell therein.
8  Let the floods clap their hands: let the hills be joyful together
9  Before the LORD; for he cometh to judge the earth: with righteousness shall he judge the world, and the people with equity.

LUKE 19:40
40  And he answered and said unto them, I tell you that, if these should hold their peace, the stones would immediately cry out.

Volcanic 'scream' precedes explosive eruptions

A change in the frequency of earthquakes may foretell explosive volcanic eruptions, according to a new study.The seismic activity changes from steady drum beats to increasingly rapid successions of tremors.
These blend into continuous noise which silences just before explosion.The study of tremors in the lead up to the 2009 eruption of Redoubt, a volcano in Alaska, appears in Journal of Volcanology and Geothermal Research.Those quakes continuously rose in pitch like a volcanic glissando - a musical glide from one pitch to another.Subterranean magma plumbing systems sit beneath volcanoes and feed pressurised molten rock toward the surface before eruptions.As the magma flows through deep conduits and cracks, it generates small seismic tremors and earthquakes.Scientists have noted earthquakes preceding volcanic eruptions before, for example drumbeat earthquakes were the first sign of renewed magmatic activity in Mount St Helens in April 2005.But the new analysis of Alaska's Redoubt volcano shows that the tremor glided to higher frequencies and then stopped abruptly less than a minute before eruption."The frequency of this tremor is unusually high for a volcano," explained Alicia Hotovec-Ellis, a doctoral student involved in the study, from the University of Washington.

What are the four ways volcanoes can kill?
"Because there's less time between each earthquake, there's not enough time to build up enough pressure for a bigger one. After the frequency glides up to a ridiculously high frequency, it pauses and then it explodes."
The earthquake noise sounds like a scream before eruption when the seismometer data are speeded up sixty times to make them audible. The authors suggest a simple model of brittle fracture may explain their results, although the precise details of what is going on underneath volcanoes before they erupt remain unclear.
Dr Marie Edmonds, from the University of Cambridge, who was not involved in the study, commented: "This work is probably the most intensive treatment of this phenomenon. If you can get an idea of what is causing these types of patterns then you have a route to prediction of volcanic eruptions."The question that arises is whether you can ever get these sorts of patterns without an eruption following?"We had repetitive sequences of volcanic explosions in the Caribbean island of Montserrat in 1997 and 2003 which were preceded by similar tremors, with hybrid earthquakes that were periodic and then recurrence intervals decreased with time before the explosion. People are converging on a view on how magmas behave."
