Dark Fiber Lays Groundwork for Long-Distance Earthquake Detection and Groundwater Mapping

In traditional seismology, researchers studying how the earth moves in the moments before, during, and after an earthquake rely on sensors that cost tens of thousands of dollars to make and install underground. And because of the expense and labor involved, only a few seismic sensors have been installed throughout remote areas of California, making…

New Simulations Break Down Potential Impact of a Major Quake by Building Location and Size

ABOVE: Images resulting from recent simulations at NERSC show the distribution of ground motion intensity across the San Francisco Bay Area region 10 and 15 seconds after a large-magnitude earthquake along the Hayward Fault. (Credit: Berkeley Lab)   With unprecedented resolution, scientists and engineers are simulating precisely how a large-magnitude earthquake along the Hayward Fault…

Dark Fiber: Using Sensors Beneath Our Feet to Tell Us About Earthquakes, Water, and Other Geophysical Phenomenon

  Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have shown for the first time that dark fiber – the vast network of unused fiber-optic cables installed throughout the country and the world – can be used as sensors for detecting earthquakes, the presence of groundwater, changes in permafrost conditions, and…
