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 ... |

According to a new computer simulation of the conditions on the remote exoplanet COROT-7b, it may be that its atmosphere has nothing in common with our own. While we may be accustomed to rain, clouds, winds, fog and snow, we would have a very hard time finding these phenomena on another planet. COROT-7b was discovere... |

The East African Rift, located in the southeastern part of the continent, is one of the most active tectonic regions on Earth, not necessarily in terms of earthquakes, but of the amount of movement that is recorded underneath the Earth's crust. In a few million years, the entire rift will be flooded, and a new s... |

The Llaima volcano, one of the most active in Chile and South America, erupted again on Friday night, prompting evacuation from areas all around it. Since its large eruption in 2008, the mountain continued to spill out lava and ash on occasions, but the most recent activity was at a large scale, so people had to flee... |

A new scientific study comes to support previous researches that showed that ancient Martian lava flows might have been cooled off faster than usual, most likely by massive floods. The rock formations exhibit the same characteristics as similar formations on Earth, and Mars is the only celestial body where such... |

Most people know that the far side of the Moon is hidden from us at all times, mostly due to the fact that the celestial body spins around its axis at about the same time it spins around our planet. For a very long time, astronomers wondered what the other side looked like, and these questions started getting answers... |

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... |

Just two days ago, the volcano with the most relentless activity in the world erupted again. Instead of the lava spills which tended to become regular until this year, it was yet another powerful explosion. It is the latest in a series of such recent events, although not the largest.One of the five volcanoes that mak... |

Although the birth of an ocean is an extremely rare phenomenon on the largest of historical scales, the geophysics is currently experiencing such an event. Even more dazzling, this occurs in one of the Earth's most inhospitable and arid regions, the Afar Depression in Ethiopia.The African continent is literally ... |

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,... |

Japan has about 200 volcanoes, of which 70 are active. The most famous Japanese volcano is Fujiyama. But this one erupted last time in 1707. Others are not that peaceful. Usu, from the island of Hokkaido, has a bizarre behavior and look. At each eruption, the underground magma rises, forming amazing mounds, from a fe... |

This is like a wound that never gets closed. In one of the hottest spots of the Earth, in the desert of northern Ethiopia, where even in the winter temperatures vary between 40 to 50oC, the volcano Erta Ale was discovered by the Europeans in 1906. The volcano is active for hundreds of years. Most volcanoes manifest t... |

The MESSENGER spacecraft made a successful fly-by of the planet Mercury last week, taking more than 1,200 pictures of the surface, some of them showing what seems to be evidence of past lava flows. Planetary scientist David Rothery said that the lava flow actually sits on top of the original surface crust that formed... |

Vulcan was the Roman god of fire, the equivalent of Hephaistos in the Greek mythology. In ancient times people regarded volcanoes as gods, which were worshiped. Old Greeks believed the Earth was a floating disc over the surface of an ocean whose storms triggered earthquakes and volcanic eruptions. Anaximander (611-54... |

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... |

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... |

Scientists have noticed a long time ago that Mars' northern and southern hemispheres are very different. While the northern hemisphere is much flatter, it is also lower than the southern hemisphere, with an elevation difference between the two of about 5 km (3 mi).In the 1980s, researchers supposed that the coll... |

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... |
