Not even the imaginative Jules Verne could guess that the temperature near the center of the Earth would be close to 6000 degrees Celsius, that is, 1000 degrees warmer than was estimated in a previous experiment carried out 20 years ago. The new measurement, released today in the prestigious journal Science, confirms geophysical models that indicate that the temperature difference between the solid core of the Earth and the mantle that surrounds it must be at least 1,500 ° C to explain why our planet has a magnetic field.
The Reunion and Mauritius islands, much frequented by tourists, have now become the focus of scientists after discovering that they hide an unknown microcontinent, according to a study published in the journal 'Nature Geoscience' in its latest edition. Its authors assure that this microcontinent of the Indian Ocean, baptized as Mauritia, broke off approximately 60 million years ago, just at the time when Madagascar and India were separated. And that since then it has remained sunk and hidden under large masses of lava. Had it remained on the surface, it would have spawned an island the size of Crete.
A huge group of rigid rocks that are part of the Sierra de Peracalç, in the Catalan Pyrenees, moves laterally in a north direction at a speed that ranges between one and three millimeters a year. It is the largest mass movement described so far in the mountain range, and has been discovered by an international group of researchers, including scientists from the Autonomous Universities of Barcelona, Gerona, Zaragoza and Modena.

The worst earthquake to shake Japan in 140 years has rocked the country's northeast coast, causing a 10-meter tsunami. These are the most impressive images of its effects.
Yes, there is. Specifically, the rain that fell millions of years ago left marks on the volcanic ash clusters that over time were transformed into rocks that scientists can use today to analyze the atmosphere of the past. This novel method has been dubbed paleobarometry.
