Chuck Bednar for redOrbit.com - Your Universe Online In what is being called one of the worst spells of seismic activity in a decade, residents of the Mammoth Lakes region of central California experienced more than 600 earthquakes in the span of 24 hours late last week. According to Willis Robinson of the Daily Mail, the so-called “earthquake swarm” started just before 5am on Thursday and the earthquakes themselves ranged in magnitude from 1.0 to 3.8. At least 109 of them were...

European Association of Geochemistry Two studies show that the movement rate of plates carrying the Earth's crust may not be constant over time. This could provide a new explanation for the patterns observed in the speed of evolution and has implications for the interpretation of climate models. The work is presented today at Goldschmidt 2014, the premier geochemistry conference taking place in Sacramento, California, USA. The Earth's continental crust can be thought of as an archive...

Lee Rannals for redOrbit.com - Your Universe Online A new study published in the journal Science reveals new information about the forces behind earthquakes. Geoscientists from the University of California, Los Angeles used a technique known as seismic tomography to study the structure of the Pacific Plate. This technique helped the team determine the plate’s thickness and image the interior of the plate and the underlying mantle, which they were able to relate to the direction of...

Oceans Earths Mantle

Lee Rannals for redOrbit.com - Your Universe Online University of Liverpool scientists believe that up to three and a half times the water of all the Earth’s oceans could be being transported beneath our feet. Seismologists reported in the journal Geology that they found deep sea fault zones could transport much larger amounts of water from Earth’s oceans to the upper mantle than previously thought. The team analyzed earthquakes that occurred more than 60 miles below the Earth’s...

April Flowers for redOrbit.com - Your Universe Online A new study from the University of Hawaii - Manoa's School of Ocean and Earth Science and Technology (SOEST) reveals that the large-scale upwelling within Earth's mantle mostly occur in only two locations: beneath Africa and the Central Pacific. Clinton Conrad, associate professor of geology at SOEST, led the team of researchers who found, despite dramatic reconfigurations of tectonic plate motions and continental locations on the...

Reassessment of the role of water in plate tectonics Water in the Earth's crust and upper mantle may not play such an important role as a lubricant of plate tectonics as previously assumed. This is a result geoscientists present in the current issue of the scientific journal Nature (13/06/2013) after the examination of water in the mineral olivine. Laboratory experiments over the past three decades have suggested the presence of water greatly weakens the mechanical strength of the...

Magma May Be Natural Lubricant For Moving Tectonic Plates
2013-03-21 11:09:11

redOrbit Staff & Wire Reports - Your Universe Online Scientists from the University of California, San Diego´s (UCSD) Scripps Institution of Oceanography (SIO) have discovered a liquefied layer of molten rock in the planet´s mantle — a substance which could be acting as a lubricant of the sliding motions of the Earth´s tectonic plates. The magma layer was discovered at the Middle America trench offshore Nicaragua during a 2010 expedition aboard the US Navy-owned...
