Nickel is one of today's most popular metals, and chances are that, as we speak, you have at least a few nickel coins in your pocket. But, in spite of its massive use in several industries, no one really knew for sure, until just recently, how the metal came to form on our planet. A new research comes to clarify... |

It would appear that Italian people have a thing for constructing their cities inside or very close to active or dormant volcanoes. This is known for Vesuvius, the mountain that buried the Roman cities of Pompeii and Herculaneum, which is located six miles (nine kilometers) away from Naples. Nearly three million peop... |

For the first time, geologists and other experts are able to show precisely how volcanoes were able to bring forth a period of sustained global cooling more than 450 million years ago. Ironically, it was precisely these volcanoes that first triggered a period of global warming during these times, by erupting almost n... |

The Greek historian and philosopher Plato represents the only Ancient account of the existence of the mythical island of Atlantis. In other words, any other evidence or tale about the “sunken island” is, in one way or the other, connected to the historian's writings. Now, experts analyzing the small ... |

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 ... |

Mount Saint Helen is one of the most dangerous volcanoes in the Pacific Northwest region of the United States, and is very well known for its tendency to spit lava, ash and other pyroclastic flows from its crater. Being a part of the Pacific Ring of Fire, it is constantly active, alongside another 160 similar volcano... |

Despite the fact that science has proven we descended from the same common ancestor as primates did millions of years ago, it's a known fact that most humans today have a remarkably similar DNA, a fact that until now raised questions as to how we failed to diversify among ourselves more. Some researchers have pr... |

Yesterday morning, Alaska's Redoubt volcano erupted twice in the early hours, sending plumes of ash tens of thousands of feet up in the air. The Alaska Volcano Observatory (AVO) issued an ash warning for the region, saying that large amounts of razor-sharp ash had been released from the crater. Reaching some 65,... |

Scientists are currently puzzled by a new find, which shows that ash and gas plumes, fresh of a volcano, behave in very much the same way as tornadoes do, during the peak of their season. In addition to spawning dust devils, large concentrations of ash and other gases can also create lightnings in the clouds above, a... |

Mount Redoubt, just 100 miles off Alaska's capital Anchorage, has erupted for the first time in 20 years, totaling a number of 6 blasts, spread out between Sunday evening and Monday evening. The dangerous eruptions have sent ash about 9 miles sky-high, and the National Weather Service (NWS) has issued an ash ale... |

While for most people volcanic eruptions are synonymous to destruction and devastation, for the environment they are nothing but good news. That is to say, the ash that is spilled into the atmosphere may pollute it with carbon dioxide, but it also contains particles that can reflect sunlight very effectively, thus lo... |

As millions of people throughout the world live underneath or close to a volcano, the necessity of finding a viable way of predicting eruptions has been an imperative to the scientific community for years now. Experts have used every technological means at their disposal the best way they could, and it would seem tha... |
