  • Seismologists introduce new measure of earthquake ruptures
    on March 21, 2018 at 6:14 pm

    A team of seismologists has developed a new measurement of seismic energy release that can be applied to large earthquakes. It provides a measure of earthquake rupture complexity that better captures variations in the amount and duration of slip along the fault for events that may have similar magnitudes. […]

  • Radar images show large swath of Texas oil patch is heaving and sinking at alarming rates
    on March 21, 2018 at 3:08 pm

    Radar satellite images show a large swath of Texas oil patch is heaving and sinking at alarming rates, according to a geophysical team. Analysis of the images with oil activity data from the Texas Railroad Commission suggests decades of oil activity have destabilized localities of the 4,000-square-mile area, which is populated by small towns, roadways and a vast network of oil and gas pipelines and storage tanks. […]

  • Historians to climate researchers: Let's talk
    on March 19, 2018 at 6:46 pm

    Ours is not the first society to be confronted by massive environmental change. Over the course of history, some societies have been destroyed by natural disasters, like Pompeii, while others have learned how to accommodate floods, droughts, volcanic eruptions and other natural hazards. The key is how a society plans for and interacts with the stress from nature. […]

    on February 26, 2018 at 5:25 pm

    Increasing stress and a lack of motivation among healthcare staff could result in hospitals having to shut down in the wake of a major incident such as flooding or an earthquake. […]

  • Earthquakes follow wastewater disposal patterns in southern Kansas
    on February 19, 2018 at 5:47 pm

    Wastewater created during oil and gas production and disposed of by deep injection into underlying rock layers is the probable cause for a surge in earthquakes in southern Kansas since 2013, a new report concludes. […]

  • Geophysicists and atmospheric scientists partner to track typhoons' seismic footprints
    on February 15, 2018 at 6:11 pm

    A remarkable collaboration between atmospheric science and geophysics could change the way we think about storms and seismicity, and could lead to an answer to the often-asked 'Are hurricanes getting stronger?' The team has identified the seismic footprint of typhoons and hurricanes, which allows climate scientists to add decades to their dataset of powerful storms. […]

  • Analysis of major earthquakes supports stress reduction assumptions
    on February 14, 2018 at 8:01 pm

    A comprehensive analysis of 101 major earthquakes around the Pacific ring of fire between 1990 and 2016 shows that most of the aftershock activity occurred on the margins of the areas where the faults slipped a lot during the main earthquakes. The findings support the idea that the area of large slip during a major earthquake is unlikely to rupture again for a substantial time. […]

  • Earthquakes continue for years after gas field wastewater injection stops, study finds
    on February 13, 2018 at 7:58 pm

    Shutting down oil and gas wastewater injection wells may not stop human-induced earthquakes quickly, say seismologists. The scientists analyzed earthquakes at DFW Airport that began in 2008 and found that even though wastewater injection was halted after a year, earthquakes continued for at least seven more years. They concluded that high-volume injection, even for a short time, can induce long-lasting seismicity when it's near a critically stressed fault. […]

  • Acoustic imaging reveals hidden features of megathrust fault off Costa Rica
    on February 12, 2018 at 5:58 pm

    Geophysicists have obtained detailed three-dimensional images of a dangerous megathrust fault west of Costa Rica where two plates of the Earth's crust collide. The images reveal features of the fault surface, including long grooves or corrugations, that may determine how the fault will slip in an earthquake. […]

  • Giant lava dome confirmed in Japan's Kikai Caldera
    on February 9, 2018 at 3:07 pm

    Researchers have confirmed that a giant lava dome was created in the Kikai Caldera, south of Japan's main islands after the caldera-forming supereruption 7,300 years ago. The dome is in the world's largest class of post-caldera volcano, with a volume of over 32 cubic kilometers. It is possible that currently a giant magma buildup may exist under the Kikai Caldera. […]

  • Earthquake simulations of California's Hayward fault
    on February 8, 2018 at 7:51 pm

    In the next 30 years, there is a one-in-three chance that California's Hayward fault will rupture with a 6.7 magnitude or higher earthquake. Scientists have used some of the world's most powerful supercomputers to model ground shaking for a magnitude 7.0 earthquake on the Hayward fault and show more realistic motions than ever before. […]

  • New map profiles induced earthquake risk for West Texas
    on February 8, 2018 at 7:14 pm

    A map created by geophysicists can help predict which parts of West Texas and New Mexico may be at risk of fracking-induced earthquakes. The map could guide oil discovery efforts in the region. […]

  • A one-two punch may have helped deck the dinosaurs
    on February 7, 2018 at 7:27 pm

    A record of volcanism preserved along ancient mid-ocean ridges provides evidence for heightened worldwide magmatic activity 66 million years ago just after the Chicxulub meteor struck Earth, according to scientists. […]

  • Oklahoma's earthquakes strongly linked to wastewater injection depth
    on February 1, 2018 at 7:15 pm

    Human-made earthquakes in Oklahoma are strongly linked to the depth at which wastewater from the oil and gas industry are injected into the ground, according to a new study. […]

  • Giant earthquakes: Not as random as thought
    on January 30, 2018 at 2:12 pm

    By analyzing sediment cores from Chilean lakes, an international team of scientists discovered that giant earthquakes reoccur with relatively regular intervals. When also taking into account smaller earthquakes, the repeat interval becomes increasingly more irregular to a level where earthquakes happen randomly in time. […]

    on January 24, 2018 at 5:31 pm

    Mathematicians have devised a way of calculating the size of a tsunami and its destructive force well in advance of it making landfall by measuring fast-moving underwater sound waves, opening up the possibility of a real-time early warning system. […]

  • Fox Creek earthquakes linked to completion volume and location of hydraulic fracturing
    on January 18, 2018 at 7:27 pm

  • Rates of great earthquakes not affected by moon phases, day of year
    on January 16, 2018 at 6:13 pm

    There is an enduring myth that large earthquakes tend to happen during certain phases of the Moon or at certain times during the year. But a new analysis confirms that this bit of earthquake lore is incorrect. […]

  • Further reducing injections of oilfield wastewater can prevent larger earthquakes
    on January 10, 2018 at 4:29 pm

    The study indicates that tracking annual data on the injection well locations can help predict how corresponding earthquake activity will change. […]

    on January 10, 2018 at 3:09 pm

    Geologists have used novel methods to analyze sediment deposits in the Japan Trench in order to gain new insights into the carbon cycle. […]

  • Shakedown in Oklahoma: To cut the number of bigger earthquakes, inject less saltwater
    on January 5, 2018 at 1:23 pm

    In Oklahoma, reducing the amount of saltwater (highly brackish water produced during oil and gas recovery) pumped into the ground seems to be decreasing the number of small fluid-triggered earthquakes. But a new study shows why it wasn't enough to ease bigger earthquakes. […]

  • Heat from below Pacific Ocean fuels Yellowstone, study finds
    on December 18, 2017 at 5:03 pm

    Recent stories in the national media are magnifying fears of a catastrophic eruption of the Yellowstone volcanic area, but scientists remain uncertain about the likelihood of such an event. To better understand the region's subsurface geology, geologists have rewound and played back a portion of its geologic history, finding that Yellowstone volcanism is more far more complex and dynamic than previously thought. […]

  • Residual strain despite mega earthquake
    on December 13, 2017 at 5:00 pm

    On Christmas Day 2016, the earth trembled in southern Chile. In the same region, the strongest earthquake ever measured occurred in 1960. A comparison of data from seismic and geodetic measurements during and after both earthquakes shows that the energy released by the 2016 quake accumulated over more than 56 years. According to this, the 1960 quake, despite its immense strength, must have left some strain in the underground. […]
