For the first time, seismologists can characterize signals as a result of some industrial human activity on a continent-wide scale using cloud computing. In two recently published papers in Seismological Research Letters, scientists from Los Alamos National Laboratory demonstrate how previously characterized “noise” can now be viewed as a specific signal in a large geographical area thanks to an innovative approach to seismic data analyses.

Applying deep learning to seismic data has revealed tremor and slip occur at all times—before and after known large-scale slow-slip earthquakes—rather than intermittently in discrete bursts, as previously believed.

Presentations on natural disasters such as earthquakes, volcanoes and their impacts will be held in Scott Hall and are open to the public at the Rutgers Geology Museum’s 52nd Annual Open House. There will also be hands-on activity sessions for kids, a mineral sale and rock and mineral identification in Scott Hall, and make-and-take stations in the Rutgers Geology Museum. Field Station Dinosaurs will bring its baby Hadrosaurus puppet and will also offer hands-on activities for visitors. All events are free and no preregistration is required.

Holidaying in a disaster zone might seem crazy, but "volunteer tourism" can actually help communities recover from natural disasters, a new study finds. And it can offer a unique and rewarding experience for volunteers, if done carefully.

An international team of geoscientists led by Caltech has used fiber optic communications cables stationed at the bottom of the North Sea as a giant seismic network, tracking both earthquakes and ocean waves.

The release of more than 50 floating sensors, called Mobile Earthquake Recording in Marine Areas by Independent Divers (MERMAIDs), is increasing the number of seismic stations around the planet. Scientists will use them to clarify the picture of the massive mantel plume in the lower mantel lying below the South Pacific Ocean. This effort will also establish one of the most comprehensive overviews of seismic activity across the globe. Frederik Simons will discuss this international effort during the marine seismoacoustics session of the 178th ASA Meeting.

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.

A UTokyo team transformed its UNICORN code into an AI-like algorithm to more quickly simulate a tectonic plate deformation that leads to earthquakes. The team ran UNICORN at 416 petaflops and gained a 75-fold speedup from a previous state-of-the-art solver using the Summit supercomputer.
