Earthquake Moved Japan Closer to U.S., Shifted Earth’s Axis, Shortened Day

Japan MovedThis is astounding. Paul Rincon reports for BBC News:

Japan’s coastline may have shifted by as much as 4m (13 ft) to the east following Friday’s 8.9 Magnitude earthquake, according to experts.

Data from the country’s Geonet network of around 1,200 GPS monitoring stations suggest a large displacement following the massive quake.

Dr Roger Musson from the British Geological Survey (BGS) told BBC News the movement observed following the quake was “in line with what you get when you have an earthquake this big”.

The quake probably shifted Earth on its axis by about 6.5 inches (16.5cm) and caused the planet to rotate somewhat faster, shortening the length of the day by about 1.8 millionths of a second.

Japan’s meteorological agency has proposed updating the magnitude of the earthquake to 9.0. [UPDATE: Has been changed to 9.0] This would make it the joint fifth biggest quake since instrumental records began, but other agencies have not yet followed suit.

New Zealand’s Lost ‘Eighth Wonder Of The World’ Found Deep Underwater

110203124824-largeKiwi scientists have discovered portions of the Pink and White Terraces, a natural wonder which was ravaged by a 19th century volcanic blast. Sadly, the remnants are buried at the bottom of a lake, meaning they will remain hidden away from the eyes of humans. Science Daily reveals:

They were called the Eighth Wonder of the World. Until the late 19th century, New Zealand’s Pink and White Terraces along Lake Rotomahana on the North Island, attracted tourists from around the world, interested in seeing the beautiful natural formations created by a large geothermal system. But the eruption of Mt. Tarawera on June 10, 1886, buried the terraces in sediment and caused the lake basin to enlarge, engulfing the land where the terraces stood. For more than a century, people have speculated whether any part of the Pink and White Terraces survived the eruption.

This week, scientists from New Zealand’s GNS Science, in collaboration with engineers and scientists from Woods Hole Oceanographic Institution (WHOI) and colleagues from Lamont-Doherty Earth Observatory of Columbia University and NOAA-PMEL, located portions of the long-lost Pink Terraces.

Can this ancient discovery help us understand future discoveries of bacteria on other planets? Via The Epoch Times:

Scientists have found prokaryotes believed to have been alive when trapped in salt crystals 34,000 years ago, according to a study published this month in The Geological Society of America’s open-access journal GSA Today.

“Microbes are known to exist in subsurface habitats, such as sub-seafloor sediments and continental and oceanic crust, to depths of up to 3 km,” the paper reads.

“Prokaryotes (single-celled organisms lacking a nucleus and other membrane-bound specialized structures) in these subsurface environments live in water within sediment pores and rock fractures.”

Organisms have also been found in glaciers up to 8 million years old, according to the paper.

Who Parked Our Moon?

Editor’s Note: This essay from Jim Marrs exploring a number of controversial ideas about the Moon was originally published in Above Top Secret: Uncover the Mysteries of the Digital Age (Disinformation, 2008).

Earthshine MoonDespite six announced visits by U.S. astronauts between 1969 and 1972, the Moon remains a riddle to scientists in many regards. The solutions to these riddles could indicate an alien aspect of our familiar Moon.

Called “the Rosetta Stone of the planets” by Dr. Robert Jastrow, the first chairman of NASA’s Lunar Exploration Committee, scientists had hoped by studying the composition of the Moon, to resolve some of the mysteries of how our planet and solar system came into existence.

However, six Moon landings later, science writer Earl Ubell declared, “… the lunar Rosetta Stone remains a mystery. The Moon is more complicated than anyone expected; it is not simply a kind of billiard ball frozen in space and time, as many scientists had believed.… Read the rest

U.S. Identifies $1 Trillion In Mineral Deposits In Afghanistan

MINERAL-articleLargeThe war in Afghanistan looks like it just got a lot bigger and longer. The New York Times reports:

The United States has discovered nearly $1 trillion in untapped mineral deposits in Afghanistan, far beyond any previously known reserves and enough to fundamentally alter the Afghan economy and perhaps the Afghan war itself, according to senior American government officials.

The previously unknown deposits — including huge veins of iron, copper, cobalt, gold and critical industrial metals like lithium — are so big and include so many minerals that are essential to modern industry that Afghanistan could eventually be transformed into one of the most important mining centers in the world, the United States officials believe.

An internal Pentagon memo, for example, states that Afghanistan could become the “Saudi Arabia of lithium,” a key raw material in the manufacture of batteries for laptops and BlackBerrys.

Instead of bringing peace, the newfound mineral wealth could lead the Taliban to battle even more fiercely to regain control of the country.

Dr. Robert Schoch on The Black Fridays!

The Black Fridays Episode 14 — Dr. Robert Schoch

Website iTunesDirect Download RSS

Robert SchochWell, what can we say? Dr. Robert Schoch! How humbling it has been to have the guests we’ve had so far! But, this goes beyond our expectations. We talk with Dr. Schoch about his findings in Bosnia and Japan and of course his discoveries that turned the scientific world on it’s head.

Dr. Robert M. Schoch, a full-time faculty member at the College of General Studies at Boston University since 1984, earned his Ph.D. (1983) in Geology and Geophysics at Yale University. He also holds an M.S. and M.Phil. in Geology and Geophysics from Yale, as well as degrees in Anthropology (B.A.) and Geology (B.S.) from George Washington University.

Dr. Schoch is the author or coauthor of both technical and popular books, including the trilogy with R. A. McNally: Voices of the Rocks: A Scientist Looks at Catastrophes and Ancient Civilizations (1999), Voyages of the Pyramid Builders: The True Origins of the Pyramids from Lost Egypt to Ancient America (2003), and Pyramid Quest: Secrets of the Great Pyramid and the Dawn of Civilization (2005).… Read the rest

Chilean Quake Likely Shifted Earth’s Axis, NASA Scientist Says

Earth's MotionsAlex Morales writes on Bloomberg:

The earthquake that killed more than 700 people in Chile on Feb. 27 probably shifted the Earth’s axis and shortened the day, a National Aeronautics and Space Administration scientist said.

Earthquakes can involve shifting hundreds of kilometers of rock by several meters, changing the distribution of mass on the planet. This affects the Earth’s rotation, said Richard Gross, a geophysicist at NASA’s Jet Propulsion Laboratory in Pasadena, California, who uses a computer model to calculate the effects.

“The length of the day should have gotten shorter by 1.26 microseconds (millionths of a second),” Gross, said today in an e-mailed reply to questions. “The axis about which the Earth’s mass is balanced should have moved by 2.7 milliarcseconds (about 8 centimeters or 3 inches).”

The changes can be modeled, though they’re difficult to physically detect given their small size, Gross said. Some changes may be more obvious, and islands may have shifted, according to Andreas Rietbrock, a professor of Earth Sciences at the U.K.’s Liverpool University who has studied the area impacted, though not since the latest temblor.
