In the South American Andes, it appears that volcanoes hold numerous surprises for researchers seeking unusual life forms, as evidenced by the fact that they have only recently discovered microbial colonies atop the 19,850-foot (6050-meter)-high Socompa volcano, located between Argentina and Chile. It would appear, t... |

On Thursday, seismologists announced that a surge in activity registered at Mount Redoubt in Alaska had prompted a widespread monitoring and observation effort on the part of all experts in the area. The volcano lies approximately 100 miles from the American state's most populous city, and there are concerns tha... |

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... |

As a result of decades of studies, Mars' dichotomous landscape is now common knowledge for scientists. It is known, for instance, that the mountainous southern hemisphere rises some 6 km (3.73 miles) above the smooth northern one, and it's much thicker. This, together with the planet's peculiar magneti... |

We have recently written about an event that nearly extinguished all life on Earth some 250 million years ago. It had to do with the most massive superplume ever that originated in the near-core region of the Earth and slowly reached towards the surface during millions of years, culminating with three large volcanic ... |

When people hear about mass extinctions of the past, they immediately think dinosaurs and asteroids, but what they don't know is that the event that occurred about 65 million years ago (at the end of the Cretaceous Period), was not the first. In fact, before they even appeared, life came close to being obliterat... |

Many experts have voiced their concerns related to the fact that we might know more about the Moon than about the Earth's oceans. Of course, by extrapolation, Earth is less familiar to us than it should be, and perhaps this has perpetuated lately neglectfulness as the source of so much trouble. Here are just a c... |

The oldest human footprints discovered to date have been confirmed to be those excavated on top of the Roccamonfina volcano in Italy in 2003. The reason it took so long to confirm them is that the teams responsible for establishing their age had to use a dating process known as argon-argon dating, where two types of ... |

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... |

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... |

The Hawaii islands is the product of the volcanoes. The archipelago, located 4,000 km (2,500 mi) away from California, was unknown to the Europeans until the voyages of James Cook, who stepped on the islands in 1778 (later, he was killed by the natives, during a visit in the archipelago). Cook named Hawaii the Sandw... |

At the bottom of the oceans, the lowest level of the ocean waters, submarine volcanoes are found. They erupt periodically, but also phenomena similar to others that accompany terrestrial volcanoes, such as submarine geysers, can be found and are called hydrothermal vents (hot vents) or black smokers. The submarine v... |

A mud volcano has nothing to do with the proper volcanoes.
