      Seismic Guidelines Underestimate Impact of 'The Big One' on Metro Vancouver Buildings

      Scientists examining the effects of a megathrust earthquake in the Pacific Northwest say tall buildings across Metro Vancouver will experience ...

      Love Waves from the Ocean Floor

      Supercomputer simulations of planetary-scale interactions show how ocean storms and the structure of Earth's upper layers together generate much of the world's seismic waves. Decoding the faint but ...

      Landslide Along Alaskan Fjord Could Trigger Tsunami

      Scientists noted that the slope on Barry Arm fjord on Prince William Sound in southeastern Alaska slid some 120 meters from 2010 to 2017, a slow-moving landslide caused by glacial melt that could ...

      Ancient Lake Contributed to Past San Andreas Fault Ruptures

      The San Andreas fault, which runs along the western coast of North America and crosses dense population centers like Los Angeles, California, is one of the most-studied faults in North America ...

      AI Detects Hidden Earthquakes

      Tiny movements in Earth's outermost layer may provide a Rosetta Stone for deciphering the physics and warning signs of big quakes. New algorithms that work a little like human vision are now ...

      Deep Magma Facilitates the Movement of Tectonic Plates

      A small amount of molten rock located under tectonic plates encourages them to move. This is what scientists have recently discovered. Their new model takes into account not only the velocity of ...

      New Evidence for Geologically Recent Earthquakes Near Portland, Oregon Metro Area

      A paleoseismic trench dug across the Gales Creek fault, located about 35 kilometers (roughly 22 miles) west of Portland, Oregon, documents evidence for three surface-rupturing earthquakes that took ...

      Lost and Found: Geologists 'Resurrect' Missing Tectonic Plate

      A team of geologists believes they have found the lost plate known as Resurrection in northern Canada by using existing mantle tomography ...

      Deep Learning Artificial Intelligence Keeps an Eye on Volcano Movements

      Radar satellites can collect massive amounts of remote sensing data that can detect ground movements -- surface deformations -- at volcanoes in near real time. These ground movements could signal ...

      Magnitude Comparison Distinguishes Small Earthquakes from Chemical Explosions in US West

      By comparing two magnitude measurements for seismic events recorded locally, researchers can tell whether the event was a small earthquake or a single-fire buried chemical ...

      Scientist Gains Fresh Insight Into the Origins of Earthquakes

      The speed and intensity with which seismic waves propagate after an earthquake depend mainly on forces occurring deep inside the rocks along a fault line, according to a new study. His sophisticated ...

      'Universal Law of Touch' Will Enable New Advances in Virtual Reality

      Seismic waves, commonly associated with earthquakes, have been used by scientists to develop a universal scaling law for the sense of touch. A team used Rayleigh waves to create the first scaling law ...

      Unusually Shallow Earthquake Ruptures in Chinese Fracking Field

      An unusually shallow earthquake triggered by hydraulic fracturing in a Chinese shale gas field could change how experts view the risks of fracking for faults that lie very near the Earth's ...

      Research May Curb Economic Losses to Power Plants After Earthquakes

      Sitting atop power transformers are bushing systems that play a critical role in supplying communities with electricity. However, these objects are also susceptible to breaking during earthquakes. ...

      Earthquake Forecasting Clues Unearthed in Strange Precariously Balanced Rocks

      Naturally formed balancing boulders could be used to help scientists to forecast large earthquakes more ...

      How Earthquake Swarms Arise

      A new fault simulator maps out how interactions between pressure, friction and fluids rising through a fault zone can lead to slow-motion quakes and seismic ...

      Flood Risks: More Accurate Data Due to COVID-19

      Emerging use of Global Navigation Satellite System (GNSS) makes it possible to continuously measure shallow changes in elevation of Earth surface. A study now shows that the quality of these ...

      Seismic Data Explains Continental Collision Beneath Tibet

      New imagery reveals the causes of seismic activity deep beneath the Himalaya region, contributing to an ongoing debate over the continental collision process when two tectonic plates crash into each ...

      Can Ripples on the Sun Help Predict Solar Flares?

      Scientists discovered in 1996 that sunquakes are linked to solar flares. Now, using helioseismic holography, scientists have analyzed a 2011 flare and shown that the impulsive source that generated ...

      Undersea Earthquakes Shake Up Climate Science

      Sound generated by seismic events on the seabed can be used to determine the temperature of Earth's warming ...

      Formation of the Alps: Detaching and Uplifting, Not Bulldozing

      Researchers have used a computer model to test a new hypothesis about the formation of the Alps while simulating seismic activity in Switzerland. This will help improve current earthquake risk ...

      Ancient Earthquake May Have Caused Destruction of Canaanite Palace at Tel Kabri

      Researchers have uncovered new evidence that an earthquake may have caused the destruction and abandonment of a flourishing Canaanite palatial site about 3,700 years ...

      Understanding Earth's 'Deep-Carbon Cycle'

      New geologic findings about the makeup of the Earth's mantle are helping scientists better understand long-term climate stability and even how seismic waves move through the planet's ...

      Superheated Rocks Deep Underground Help Explain Earthquake Patterns

      By researching tremors under the infamous San Andreas Fault, scientists are seeking out what's brewing beneath a quake's ...
