A new active fault system has been discovered off the coast of Portugal, which scientists believe could be the first signs of an eventual convergence of the North American and Eurasian tectonic plates.

L'Aquila earthquake scientists sentenced to six years in jail - Telegraph

L'Aquila earthquake scientists sentenced to six years in jail - Telegraph | Platetectonics | Scoop.it
Six Italian scientists and a government official have been found guilty in a watershed trial of multiple manslaughter for underestimating the risks of the L'Aquila 2009 earthquake.

The landmark decision on Monday was welcomed by victims and their families but immediately prompted uproar from the scientific community, which contends that there is no reliable way of predicting earthquakes.

Earth's core far hotter than thought - 6,000 ˚C, as hot as sun surface

Earth's core far hotter than thought - 6,000 ˚C, as hot as sun surface | Platetectonics | Scoop.it

The solid iron core is actually crystalline, surrounded by liquid.

But the temperature at which that crystal can form had been a subject of long-running debate.

 

Experiments outlined in Science used X-rays to probe tiny samples of iron at extraordinary pressures to examine how the iron crystals form and melt.

Seismic waves captured after earthquakes around the globe can give a great deal of information as to the thickness and density of layers in the Earth, but they give no indication of temperature.

 

That has to be worked out either in computer models that simulate the Earth's insides, or in the laboratory. Measurements in the early 1990s of iron's "melting curves" - from which the core's temperature can be deduced - suggested a core temperature of about 5,000˚C.

 

"It was just the beginning of these kinds of measurements so they made a first estimate... to constrain the temperature inside the Earth," said Agnes Dewaele of the French research agency CEA and a co-author of the new research. 

 

"Other people made other measurements and calculations with computers and nothing was in agreement. It was not good for our field that we didn't agree with each other."

 

The core temperature is crucial to a number of disciplines that study regions of our planet's interior that will never be accessed directly - guiding our understanding of everything from earthquakes to the Earth's magnetic field.

New measurements suggest the Earth's inner core is far hotter than prior experiments suggested, putting it at 6,000C - as hot as the Sun's surface.

great article since we just spoke about the fact due to the intense pressure that the core of Earth is as hot as the sun's surface--great reinforcement of material being covered
