  • Idaho started shaking March 31. Why hasn’t it stopped? Geologists research Sawtooth fault

    The shaking started March 31. That’s when the Sawtooth mountain range in central Idaho trembled with a 6.5-magnitude earthquake — the second strongest ever recorded in Idaho. From that very moment, geologists rushed to the epicenter area — 45 miles west of Challis — to start collecting valuable information that could help them understand what happened. Three months later, the rumbling still hasn’t subsided as aftershocks continue to jar the area. But now scientists have a better idea of what may have led to the major earthquake — and it’s helping them uncover some other secrets buried under Idaho’s soil....
  • Part of Earth's Magnetic Field is Getting Weaker in 'Vigorously' Developing Anomaly, Scientists Say

    Using satellite data, researchers believe an "anomaly" in the South Atlantic may have split in two, with the eastern section "developing vigorously." Earth's magnetic field is generated by movements within the planet's molten iron core. ...When the magnetic field is stronger, it blocks more radiation. When it is weaker, more radiation reaches the planet's surface. The magnetic field is constantly moving. It strengthens and weakens as part of normal fluctuations. According to the European Space Agency, the magnetic field has lost around 9 percent of its strength over the preceding two centuries. One section of the magnetic field has been...

    Lambart and her colleagues from Wales and the Netherlands, sought to discover what the mantle looks like before it rises as lava at a mid-ocean ridge. They examined cores, drilled through the ocean crust, to look at cumulate minerals: the first minerals to crystallize when the magmas enter the crust. They analyzed the samples centimeter by centimeter to look at variations in isotopes of neodymium and strontium, which can indicate different chemistries of mantle material that come from different types of rock. The amount of isotope variability in the cumulates was seven times greater than that in the mid-ocean ridge...

    Wood Buried Under Ocean Floor Thousands of Miles at Sea October 22, 2019 | David F. Coppedge Wood chips hundreds of feet deep in ocean sediments have been found. How did they get there? Watch out for ocean trees. Geology researchers from the University of Southern California (USC) went boring into ocean sediments near India, and were surprised to find direct evidence that “Catastrophic events carry forests of trees thousands of miles to a burial at sea.” They pulled up six cores of sediment from the ocean floor a thousand feet below the surface. The cores were extracted miles apart...

    Research reveals that plate tectonics started on Earth 600 million years before what was believed earlier... Where it was previously thought that plate tectonics started about 2.7 billion years ago, a team of international scientists used the microscopic leftovers of a drop of water that was transported into the Earth's deep mantle - through plate tectonics - to show that this process started 600 million years before that. An article on their research that proves plate tectonics started on Earth 3.3 billion years ago was published in the high impact academic journal, Nature, on 16 July... For their research, the...

    The Truth about Radiometric Dating June 2019 Prove it. That’s the challenge biblical creationists often face when discussing the scientific validity of the Genesis creation account with skeptics. Many people leave the church, especially young adults, when they think that the Bible and science can’t be harmonized. But what if incredible harmony actually exists? Those who believe in millions and billions of years often point to radiometric dating as indisputable scientific proof that Earth is old. Since the biblical timeline indicates a young earth that’s only about 6,000 years old, creation scientists must address the radiometric dating issue. We need...

    How valleys and canyons formed during Noah’s Flood by Micheal Oard Continental valleys and canyons come in all sizes and shapes. Some are V-shaped valleys, and others U-shaped canyons. Some are shallow and others have tall vertical walls, like the Grand Canyon. We rarely observe valley and canyon formation taking place today and then only in association with a flooding event. Therefore, uniformitarian1 theories about valley and canyon formation are not built on observational science but instead upon their assumptions about the past.

    The Grand Canyon is a gigantic geological library, with rocky layers that tell much of the story of Earth’s history. Curiously though, a sizeable layer representing anywhere from 250 million years to 1.2 billion years is missing. Known as the Great Unconformity, this massive temporal gap can be found not just in this famous crevasse, but in places all over the world. In one layer, you have the Cambrian period, which started roughly 540 million years ago and left behind sedimentary rocks packed with the fossils of complex, multicellular life. Directly below, you have fossil-free crystalline basement rock, which formed...

    A hidden "super volcano" near Pompeii threatens an eruption that could make Vesuvius look like a picnic, scientists warn. The Phlegraean Fields zone of intense seismic activity -- which the ancient Romans believed was the gateway to hell -- could doom millions of people in the Naples area if it erupts, Reuters reports. Scientists plan to drill more than two miles below its surface to monitor any signs of a pending eruption in the huge chamber of molten rock, but some experts fear that the drilling itself could trigger an earthquake or eruption. Areas like the Phlegraean fields "can give...

    Scientists have discovered a stunning volcanic ‘lost world’ off the coast of Tasmania. Experts on the Commonwealth Scientific and Industrial Research Organisation (CSIRO), vessel ‘Investigator’ made the find while mapping the seafloor 249 miles east of Tasmania. The project is led by scientists from the Australian National University. CSIRO is Australia’s national science agency. A chain of ‘seamounts’, or undersea mountains, were spotted in deep water, offering the first glimpse of a spectacular “underwater world.” Scientists say that the mountains rise up to 9,843 feet from the seafloor, but the highest peaks are still 6,562 feet beneath the waves. “Our...

    Tiny holes in the bones indicate that they passed through a large bird’s digestive system, according to Professor Pawel Valde-Nowak of the Jagiellonian University in Krakow. It’s not clear, however, whether the bird attacked and ate the young Neanderthal or scavenged the remains of a dead child. Believed to be about 115,000 years old, the bones are the oldest human remains ever discovered in Poland. Experts from the Jagiellonian University and Washington University in St. Louis confirmed that the remains are digital bones from a child’s hand. The Archaeological Museum of Krakow and the Polish Academy of Sciences also participated...
  • Jupiter's Icy Moon Europa Has a Really Weird Cold Spot

    Just because Jupiter's moon Europa is coated in ice doesn't mean all that ice is the same temperature. And now, scientists have mapped the hot and cold spots on the moon's surface using data gathered from Earth, with accuracy down to 125 miles (200 kilometers). While most of the temperature variations they measured can be explained by sunlight's influence on the ice, there's one unusually cold spot that is stumping the scientists behind the new research. That spot, which falls on the moon's northern hemisphere, stood out in images taken at different times of the day, which surprised the scientists....

    The Meghalayan...runs from 4,200 years ago to the present. It began with a destructive drought, whose effects lasted two centuries, and severely disrupted civilisations in Egypt, Greece, Syria, Palestine, Mesopotamia, the Indus Valley, and the Yangtze River Valley.

The middle phase of the Holocene will be referred to as the Northgrippian, and runs from 8,300 years ago up to the start of the Meghalayan. The onset for this age was an...
  • Geologists surprised to find huge magma blob under Massachusetts, Vermont and New Hampshire

    Something unexpected has been gradually making itself known to geologists in the United States. A huge mass of molten rock is creeping upwards beneath the nation’s north eastern states. “The upwelling we detected is like a hot-air balloon, and we infer that something is rising up through the deeper part of our planet under New England,” says Rutgers University geophysicist Professor Vadim Levin. Traces of the brooding mass only became evident through a large-scale new seismic study. The idea that there may be a super volcano brewing under Massachusetts, Vermont and New Hampshire is something of a surprise. ..." So...

    New York City could be hit with a $39 billion in damage with 30 million tons of debris clogging the streets if a long-overdue earthquake hit. The city of 8.5 million people is not thought of as a tremor hot spot, but the five boroughs are riddled with fault lines that could bring dozens of buildings down. Because the city is so dense and littered with thousands of tall buildings, even a 5.0 magnitude earthquake nearby would cause such damage, experts fear.

    Once upon a time there was a massive flood across the Mediterranean Sea, an in-pouring of water so huge that it excavated a canyon five kilometres deep and 20 kilometres long, and created a waterfall with a 1.5 kilometre drop. Evidence for the great flood, long hypothesised, has now been found by a team of researchers led by geoscientist Aaron Micallef from the University of Malta. And while several Mediterranean traditions feature great flood narratives, the earliest arising from Sumeria and already well enough known to be recorded in cuneiform by the seventeenth century BCE, this one is unlikely to...
