  • Six key impact areas of shale oil and gas development in Texas
    on June 19, 2017 at 1:22 pm

    A comprehensive review of the impacts of oil and gas development in Texas by a cross-disciplinary task force of top researchers finds a wide range of both benefits and consequences for the state's environment and communities. […]

  • Seasonal rain and snow trigger small earthquakes on California faults
    on June 15, 2017 at 6:28 pm

    California's earthquake faults continually accumulate stress until they fail in an earthquake. Seismologists studied the impact of the flexing of Earth's crust under the load of winter rains and subsequent unloading during summer drought, and found that the up and down movement of the mountains changes the stresses on the state's faults, making them fail slightly more often as the snows melt and the rivers drain in late summer and early fall. […]

  • Japanese slow earthquakes could shed light on tsunami generation
    on June 15, 2017 at 6:27 pm

    Understanding slow-slip earthquakes in subduction zone areas may help researchers understand large earthquakes and the creation of tsunamis, according to researchers who used data from instruments placed on the seafloor and in boreholes east of the Japanese coast. […]

  • Seismic CT scan points to rapid uplift of Southern Tibet
    on June 7, 2017 at 4:39 pm

    Geophysicists have conducted a three-year seismic CT scan of the upper mantle beneath the Tibetan Plateau and concluded that the southern half of the 'Roof of the World' formed within 10 million years, or less than one-quarter of the time since the beginning of the India-Eurasia continental collision. […]

  • New evidence reveals source of 1586 Sanriku, Japan tsunami
    on June 6, 2017 at 9:03 pm

    A team of researchers re-examined historical evidence around the Pacific and discovered the origin of the tsunami that hit Sanriku, Japan in 1586 -- a mega-earthquake from the Aleutian Islands that broadly impacted the north Pacific. Until now, this was considered an orphan tsunami, a historical tsunami without an obvious local earthquake source, likely originating far away. […]

  • Why the Sumatra earthquake was so severe
    on May 25, 2017 at 6:15 pm

    An international team of scientists has found evidence suggesting the dehydration of minerals deep below the ocean floor influenced the severity of the Sumatra earthquake, which took place on Dec. 26, 2004. […]

  • US nuclear regulators greatly underestimate potential for nuclear disaster
    on May 25, 2017 at 6:15 pm

    The US Nuclear Regulatory Commission relied on faulty analysis to justify its refusal to adopt a critical measure for protecting Americans from nuclear-waste fires at dozens of reactor sites around the country, according to a recent article. Radioactivity from such a fire could force approximately 8 million people to relocate and result in $2 trillion in damages. […]

  • The birth and death of a tectonic plate

  • Atlas of the Human Planet 2017: How exposed are we to natural hazards?
    on May 24, 2017 at 12:55 pm

    One out of three people in the world is exposed to earthquakes, a number which almost doubled in the past 40 years. Around 1 billion in 155 countries are exposed to floods and 414 million live near one of the 220 most dangerous volcanoes. The 2017 edition of the  Atlas of the Human Planet looks at the exposure of people and built-up areas to the six major natural hazards, and its evolution over the last 40 years. […]

  • Supercomputing helps researchers understand Earth's interior
    on May 23, 2017 at 12:19 pm

    Geologists have created a computer model of tectonic activity so effective that they believe it has potential to predict where earthquakes and volcanoes will occur. Scientists focused on the deep mantle and its relationship to plate tectonics. […]

  • Aftermath of supereruption shows Toba magma system's great size
    on May 16, 2017 at 6:34 pm

    The rare but spectacular eruptions of supervolcanoes can cause massive destruction and affect climate patterns on a global scale for decades -- and a new study has found that these sites also may experience ongoing, albeit smaller eruptions for tens of thousands of years after. […]

  • From where will the next big earthquake hit the city of Istanbul?
    on May 16, 2017 at 2:47 pm

    Scientists reckon with an earthquake with a magnitude of 7 or greater in this region in the coming years. The extent of such seismic threat to this Turkish city of Istanbul actually depends on how strongly the tectonic plates are entangled and on the exact nucleation point of the earthquake. A team of researchers now presents a study indicating that the next major earthquake is more likely to originate in Istanbul's eastern Marmara Sea. […]

  • Porewater salinity: Key to reconstructing 250,000 years of Lake Van’s history
    on May 16, 2017 at 1:11 pm

    The sediments of Lake Van in Eastern Anatolia (Turkey) are a valuable climate archive. Now, using the salinity measured in sediment porewater, scientists have reconstructed the huge lake-level fluctuations that occurred over the past 250,000 years. This approach – based on simple physical concepts – is likely to be more widely applied in the future. […]

  • What goes down, must come up: Stirring things up in the Earth's mantle
    on May 12, 2017 at 1:39 pm

    New insights into the convection patterns of the Earth's mantle and its chemical makeup have been revealed. The new findings suggest that the mantle does not flow ubiquitously, as has been previously thought - and that it is instead divided into two very large domains that convect only within themselves, with little evidence of them mixing together. […]

  • Wastewater injection rates may have been key to Oklahoma's largest earthquake
    on May 2, 2017 at 6:24 pm

    Changes to the rate of wastewater injection in disposal wells may have contributed to conditions that led to last year's Pawnee earthquake in Oklahoma, according to a new report. […]

  • Geologists use radioactive clock to document longest earthquake record
    on May 2, 2017 at 4:12 pm

    Using radioactive elements trapped in crystallized, cream-colored 'veins' in New Mexican rock, geologists have peered back in time more than 400,000 years to illuminate a record of earthquakes along the Loma Blanca fault in the Rio Grande rift. It is the longest record of earthquakes ever documented on a fault. […]

    on April 27, 2017 at 3:22 pm

    Every year, worldwide wine industry suffers losses of more than ten billion US dollars from damaged assets, production losses, and lost profits due to extreme weather events and natural disasters. A multidisciplinary team examined the extent to which regions are affected by the risks and how climate change influences wine industry. […]

  • Tsunami formation: Study challenges long-held theory
    on April 26, 2017 at 8:47 pm

  • New model could help predict major earthquakes
    on April 26, 2017 at 1:23 pm

    Researchers have characterized several earthquakes that struck South America's west coast over the last 100 years by using seismographic data, tsunami recordings, and models of the rapid plate movements associated with these natural disasters. The team showed that some earthquakes were linked to the same sites of rupture at plate boundaries and others to different sites. Thus, they revealed the periodicity and intensity of earthquakes associated with particular sites, potentially aiding future earthquake prediction. […]

    on April 18, 2017 at 3:52 pm

    An effective communication approach incorporating computer simulations could help people find practical means to evacuate in the event of a tsunami. […]

  • Lessons from Parkfield help predict continued fault movements after earthquakes
    on April 17, 2017 at 6:49 pm

    A new study shows that the San Andreas Fault continued to slip gradually for six to 12 years after the 2004 magnitude 6.0 Parkfield, Calif., earthquake, raising the issue of continued damage to structures built across fault zones after damaging earthquakes. […]

  • Forecasting large earthquakes along the Wasatch Front, Utah
    on April 13, 2017 at 4:00 pm

    There is a 43 percent probability that the Wasatch Front region in Utah will experience at least one magnitude 6.75 or greater earthquake, and a 57 percent probability of at least one magnitude 6.0 earthquake, in the next 50 years, say researchers. […]

  • Developing a microinsurance plan for California earthquakes
    on April 12, 2017 at 3:57 pm

    Nine out of 10 Californians are uninsured against earthquake risk, which could slow economic recovery in neighborhoods and cities around the state after a damaging quake. On-demand or use-based small insurance policies -- sometimes called microinsurance -- could help fill in that financial gap. […]
