Some 251.4 million years ago, the Permian Age came to an abrupt end, when a massive extinction event, known among experts as the “Great Dying”, killed off just about everything on the planet, with just a few exceptions. The event marked the beginning of the Triassic Age, and experts have been puzzling ove... |

Geologists recently announced that there might be more things that Mount St. Helens, Mount Rainier and Mount Adams have in common, other than the fact that they are all volcanoes. Preliminary studies seem to indicate that they draw their lava from the same enormous magma pool that spans the entire southwestern portio... |

All volcanic eruptions are dangerous and powerful, obviously, but, among them, the Plinian type takes the cake. It includes extremely intense eruptions that regularly take place after many years of volcanic inactivity, and it is, at times (but not always), preceded by short periods of seismic activity. For the first ... |

Back in the days when our planet was very young, the continents and oceans did not resemble anything we know and see today. The outer layer of the planet, the crust, was in a constant process of rearrangement, and volcanic eruptions were a common thing. But, from time to time, crust explosions at a grand scale took p... |

Online videos are a huge success, with viewer numbers and content growing month after month. Their biggest drawback, in fact, is precisely their success as, with the millions of new videos created and uploaded every month and roughly 15,000 hours’ worth of video added to YouTube every day, it's almost impo... |

A new geological theory gives rise to the belief that our planet has two inner cores instead of one, as scientists believed until now. That's not to say that the new theory proved correct. In fact, it's very difficult to say what exactly lies at the center of the Earth, as studying the region is nearly impo... |

Another lucky strike for science came in the form of an accidental discovery of magma, following the drill operations conducted in Hawaii by a commercial geologist. Magma has never before been studied in its original form, and the many computer models were built based on the properties inferred from its cooler, gas-f... |

We know how the seven continents are arranged today and we are aware (and it's easy to observe) that they were once grouped up in a single, massive continent, called Pangaea. But what's the mysterious force that caused the division of the continents and keeps moving them apart? New studies associate the con... |

Canadian researchers have uncovered what may be the oldest chunk of Earth's crust, but the sparks lit by some techniques used in order to date the rocks may cast doubt over the whole finding. For the past four years, Jonathan O'Neill and his colleagues from the McGill University in Canada have been obs... |

Most of the platinum metal extracted around the world comes from the Bushveld Complex located in South Africa, a region believed to have been created out of ancient magma some two billion years ago. However, why that particular area is so rich in platinum and other related metals remained a topic open for debate for ... |

Volcanoes are the result of the tectonic movements of the Earth's crust, when magma from the entrails of the planet goes out as lava. They became present in the legends and mythology of all people living around them, which venerated and feared them at the same time. There are submarine and terrestrial volcanoes,... |

Recently an alternative theory designed to contest the notion that Earth's mantle, the layer between the outer crust and the inner core, might have been solid, suggests that instead it could have consisted of a thick magma 'ocean', slowly flowing beneath the surface.Evidence collected from seismic even... |

Scientists say that it takes less time for a planet to form, than for it to completely cool down and compose a solid crust. The study was based on the small meteorites, which occasionally land on the Earth's surface. Physicists from the Lunar and Planetary Institute in Houston, Texas, UC Davis and NASA, found th... |

The experiment was conceived by the U.S. Department of Energy's Argonne National Laboratory, to determine how oxide glass structures behave under extreme pressures. A diamond cell was uniquely constructed using a microscopic laser, to house pressures up to 32 gigapascals, equivalent to a tenth of the pressure at... |

The world "volcano" comes from the Roman god of fire Vulcan, the equivalent of Hephaistos in the Greek mythology. In the ancient times, people attributed to the volcanoes a supernatural personality, which was worshiped. Old Greeks believed the Earth was a floating disc over the surface of an ocean whose storms trigge... |

Surprising new photos were presented by the ESA today, showing one of the most beautiful and unusual features on the surface of Mars. Deuteronilus Mensae is situated North of Arabia Terra, bordering the northern lowlands and the southern highlands.At latitude of 39° North and 23° East, it's glacial formation wi... |

Mauna Loa is one of the five volcanoes making up the Hawaii Island, the Earth's largest one, with a volume estimated at about 18,000 cubic miles (75,000 km³).The way the massive volcano is bulging and the swelling could enable the researchers to forecast when the next massive eruption will occur. Better prognose... |

Northwestern US is not given to rest: Mount St. Helens seems to enter the same cycle followed by Kilauea in Hawaii with magma being replaced from an reservoir located under the volcano at the same pace as it goes out as lava at the surface. "While the two volcanoes are different in many respects, St. Helens appears t... |

During the antiquity, people attributed to the volcanoes a supernatural personality, which was worshiped. Now, researchers just focus on achieving the right methods of preventing the volcanic eruptions and decreasing the damages they inflict.Under the terrestrial crust, the rocks are under molten stage, forming the m... |
