Machine learning unearths signature of slow-slip quake origins in seismic data
Los Alamos National Laboratory

Combing through historical seismic data, researchers using a machine learning model have unearthed distinct statistical features marking the formative stage of slow-slip ruptures in the earth’s crust months before tremor or GPS data detected a slip in the tectonic plates. Given the similarity between slow-slip events and classic earthquakes, these distinct signatures may help geophysicists understand the timing of the devastating faster quakes as well.

Researchers catch a wave to determine how forces control granular material properties
Lawrence Livermore National Laboratory

Stress wave propagation through granular material is important for detecting the magnitude of earthquakes, locating oil and gas reservoirs, designing acoustic insulation and designing materials for compacting powders. A team of researchers including Lawrence Livermore National Laboratory (LLNL) physicist Eric Herbold used X-ray measurements and analyses to show that velocity scaling and dispersion in wave transmission is based on grainy particle arrangements and chains of force between them, while reduction of wave intensity is caused mainly from grainy particle arrangements alone.

Stormquakes are a recently discovered phenomenon characterized by seismic activity originating at the ocean floor due to powerful storms. Heavy storms, like hurricanes or nor'easters, can create seismic waves as large as magnitude 3.5 quakes. These tremors caused by the effects of storms on the seafloor are what researchers call stormquakes. Catherine de Groot-Hedlin, who was part of the group that first observed stormquakes, will discuss their properties and meteorological significance at the 178th ASA Meeting.
