Scientists found a tectonic plate that reveals an ancient sea that once existed in the region shortly after the dinosaur era.
Around 73,000 years ago, the towering predecessor of the Fogo volcano - one of the most active in the world - collapsed. As a result, a unbelievably massive tsunami rippled across the Atlantic Ocean, washing its destructive force over islands that now boast over 250,000 human residents. Experts now wonder if such a disaster is more common than we'd like.
If it weren't for iron and fire, we could be a much older species that we are now. Researchers from the Universities of Tübingen and Alberta claim that the heavy metals spewed from subsea volcanoes in Earth's adolescence poisoned early life on earth, delaying a boom in oxygen and life for a half-a-billion years.
If diamonds truly are a girl's best friend, an unusual formation recently found in Russia may be the friendliest rock in the world. The rock, small enough to fit in the palm of your hand, was found to contain a stunning 30,000 tiny diamonds and could provide important clues to Earth's geologic history.
Mars' Olympus Mons, the tallest mountain in our solar system, stretches three times the height of Mount Everest, Earth's tallest mountain. So why can't our mountains grow as tall? New research argues that Earth's glaciers just won't let them.
Mars is home to the largest known canyon system in our solar system, and while the jury is still out on what exactly formed these canyons - be it water or lava - we do finally know what helped form the unusually hilly geological formations that can be found in their depths.
Australia, despite being a massive island and continent of its own, has only one active volcanic region, and this spot has seen about 400 volcanic events in the last four million years. Now researchers have discovered the unique process that allows these eruptions to occur in a portion of the globe that is nearly devoid of volcanic activity.
A study details how mantle plumes may cause massive rift systems where they otherwise should not be. However, other geologists have long argued that these theoretical plumes don't even exist. A new 3D model may help get to the bottom of this subterranean mystery.
It seems that all this time, the Earth's tectonic plates have just been warming up, and now they've set the treadmill to a higher setting. That is, according to a new study, which claims that Earth's tectonic plates are moving faster now than at any other point in the last two billion years.
A group of citizen scientists have been saving people's lives around the "Throat of Fire" Tungurahua volcano in the Ecuadorian Andes for nearly 15 years now. A new report details the success of this network of volunteers as they struggle to preserve the lives of people who chose to live around active volcanoes.
Research conducted on Jeju Island, a popular vacation spot just south of South Korea, has revealed that the island's massive volcano is likely still active, having erupted within the last 5,000 years.
Researchers are taking a close look at the "volcano plumbing" of Mount St. Helens, looking deeper and closer than they claim science has ever looked before.
Strangely enough, experts have never physically seen what they theorize is Earth's most abundant mineral, until now. Finding traces of this mineral in a meteorite, researchers finally have enough hard physical evidence of its existence and properties to give it a name - bridgmanite.
